There comes an evening when the kitchen table is covered in notes. One has a number on it, another a waiting list, and somewhere between them lies the real question: what is right for our child – and what can we sustain as a family?
For most parents in Switzerland, that calculation begins towards the end of maternity leave. Fourteen weeks pass quickly, and returning to work brings a decision that feels momentous – because it is. Nanny or nursery is rarely a simple question of right or wrong. It is about structure, risk, budget and what your child will need over the next three to five years.
This guide compares the two forms of childcare as objectively as possible: legally, financially and, above all, from a developmental perspective. It draws on current Swiss rules, international and Swiss childcare research, and twenty-five years of daily work with children aged six months to six years. Every source is listed individually at the end.
Nannies and nurseries differ in six fundamental respects: staff-to-child ratio, cover for absences, regulatory oversight, contact with peers, the parents' role as employer and the way costs scale. A nanny is a private employment arrangement; a nursery is a licensed and supervised early-years setting.
Before we go into depth, the overall overview. It shows that the two models differ not only in degree, but in their basic construction – and that most of the advantages and disadvantages follow directly from this construction, not from the quality of individual providers.
Criteria | Nanny | nursery |
|---|---|---|
Care location | Your home | Approved setting |
Staff-to-child ratio | 1:1 or 1:number of siblings | Age dependent; significantly narrower for infants than for preschool children |
Legal relationship | You are an employer | Childcare contract with a provider |
Supervision | No regulatory oversight | Cantonal approval, periodic supervisory visits |
Absence due to illness | You organise a replacement – and continue to pay | Is taken care of internally in the team |
Holidays | Paid for at least four weeks, appointments can be coordinated | Company holidays or year-round support, known in advance |
Contact Peers | Must be actively organised | Daily and casually |
Educational approach | Depends on the individual | Binding, written, approval requirement |
Development documentation | Usually none | Observation, portfolio, development discussions |
Subsidies | No childcare vouchers, no childcare allowance | Income-dependent contributions and vouchers possible |
Tax deduction | Yes, provided the nanny is formally employed | Yes |
Flexibility during hours outside nursery opening times | Very high | Bound to opening hours |
Research situation | Very thin | Extensive, international and in Switzerland |
Briefly explained
Why the comparison so often goes wrong. Many parents compare a nursery's day rate with a nanny's hourly wage. That means comparing an all-inclusive price with only one component of the cost.
A nursery's day rate covers staff, premises, insurance, cover for absences, professional development and quality management. A nanny's hourly wage covers only their pay. Social-security contributions, paid holidays, continued salary payments during illness and replacement childcare all come on top – and they are substantial.
The data help put your own circumstances in context. The Federal Statistical Office's Families and Generations Survey shows that 62 per cent of children under thirteen use non-parental childcare. Just over a third attend a nursery or out-of-school setting, while 28 per cent are cared for by grandparents. Among children under four, grandparents are the most common single form of childcare, at 35 per cent.
Regional differences are significant. Across Switzerland, 44 per cent of households with children under the age of thirteen use institutional services – in the large cities, including Zurich and Winterthur, the figure is 71 per cent.
In numbers
Statistically, nannies are uncommon. In the Federal Statistical Office's classification, nannies, au pairs and babysitters fall under non-institutional childcare, alongside grandparents, relatives and acquaintances. Almost 30 per cent of children using non-parental childcare rely exclusively on this group of arrangements.
Grandparents dominate within this category. Paid carers in the child's own home are so uncommon that most statistics do not report them separately. This has an awkward consequence: there is very little robust research on nanny care – not because it is poor, but because it is too rare to study at scale.
A nanny offers lower levels of stimulation, undivided attention, a day shaped around the child's own rhythm and a high degree of flexibility. Meta-analyses also show that secure attachments to childcare practitioners form more often in home-based settings than in group settings.
The advantages of a nanny are more likely to be underestimated than overestimated in public discourse – probably because they are harder to exploit politically. But they are real, and some of them can be measured.
A six-month-old baby who sleeps, eats and spends their waking hours at home experiences a very different day from a baby in a group. That is not speculation; it is one of the best-documented findings in childcare research.
Harriet Vermeer and Marinus van IJzendoorn reviewed nine studies that measured children's cortisol levels – an established marker of stress – both at home and in centre-based childcare. The pattern was consistent: at home, cortisol fell over the course of the day, as the normal daily rhythm would predict. At nursery, it rose from morning to afternoon. Across seven comparable studies involving 303 children, the researchers found a significant effect. The rise was particularly pronounced in children under three.
The classification is important, and it has two sides. Elevated cortisol is not damage, but rather an adaptive response – the body adjusting to a more demanding environment. A group with eight children, changing adults, noise levels and the need to divide attention is objectively more demanding than a living room. At the same time, the authors are cautious: the effect is moderate, and no one has yet been able to show that it causes long-term harm.
A secondary finding from a study by Groeneveld and colleagues is especially revealing: the afternoon rise was absent in settings with higher-quality care, measured by practitioners' sensitivity and noise levels. In other words, it is not the group itself that creates stress, but a group operating under unfavourable conditions.
Briefly explains
What cortisol says – and what it doesn't. Cortisol is a hormone that is released when required. It increases with excitement, exertion and new things – not just with suffering. A child who enthusiastically conquers a group can have the same value as one who feels uncomfortable.
The value only becomes meaningful in the pattern: If it remains elevated for months instead of normalizing after settling in it, this is an indication that the situation is permanently too demanding for this child. That's exactly why the course of the first few months is more important than the first day.
This point rarely appears in nursery brochures, but it belongs in an honest assessment. Lieselotte Ahnert, Martin Pinquart and Michael Lamb combined forty studies involving 2,867 children, whose average age was just under thirty months. They examined how often children formed a secure attachment to a non-parental childcare practitioner.
Secure attachments to childcare practitioners were more common in home-based settings than in group settings. They also became more likely the longer the child had been in the setting – unsurprisingly, attachment takes time.
The crucial additional finding is subtler and often overlooked. In small home-based settings, sensitivity towards the individual child predicted attachment security. In group settings it did not. There, another factor mattered: group-related sensitivity – a practitioner's ability to read and guide the group as a whole.
For parents, that means asking two different questions. With a nanny: is this person sensitive and responsive towards this child? With a nursery: can this team guide a group without individual children being overlooked? If you focus only on the attention given to your own child during a visit, you are assessing the wrong criterion for a nursery.
In a group, the daily routine is a compromise between eight sets of needs. At home, it reflects only one. That may sound like a small convenience, but it affects the areas in which young children have the least capacity to compromise: sleep and food.
During the first year, both rhythms are still changing. Over the first eighteen months, sleep develops from several short periods into one or two longer daytime naps, and children vary by months in when they move from two naps to one. At home, this presents no organisational problem: the child sleeps when tired. In a group, the transition has to be managed.
An Australian research group led by Sally Staton and Karen Thorpe has investigated how serious this is – and the findings are also useful for Swiss parents because they raise a very specific question for every institution.
An observational study showed that around seventy per cent of children do not sleep at all during their scheduled bedtime. What matters is what happens to them during this time. In a cortisol study, children who slept and children who were allowed to stay awake and do something else had decreasing levels over the afternoon – the normal course. Children who did not sleep but had to stay lying down had elevated values throughout the afternoon and even in the evening at bedtime. Another study by the same group found a connection between rigid sleep schedules and shorter nights of sleep – proven right into the school years.
The conclusion is not that ‘home is better’. It is that rigid sleep schedules are the problem, not the group. A setting that lets children sleep according to need and gives those who remain awake a quiet alternative does not produce this effect. At home, that flexibility comes automatically; at nursery, it depends on the approach and the staff-to-child ratio, because supervising sleeping and awake children separately requires staff.
Practical tip
Perhaps the most underrated question to ask on a visit: ‘What happens if a child is not tired at nap time?’
Good answers sound like this: the child may get up; there is a quiet adjoining room; someone reads to them or offers a calm activity. Less reassuring answers sound like this: the child must lie quietly so that the others can sleep. Also ask whether babies may sleep according to their individual rhythm or must follow the group's timetable.
The same applies to food. During the first year, while a baby is still fed responsively and moves on to solid foods at an individual pace, home-based care has a structural advantage. From around eighteen months, that often reverses: eating with other children is one of the most effective ways to broaden a restricted diet, because children are more willing to try an unfamiliar food when they see their peers eating it.
A child's individual rhythm remains particularly important where there are additional care needs, a chronic condition, premature birth or marked sensitivity to stimulation. Group care is not impossible for these children, but it places greater demands on the nursery's approach; home-based care removes that pressure entirely.
Nursery opening hours are typically 7.00 or 7.30 a.m. to 6.00 or 6.30 p.m. That covers most working patterns. For a sizeable minority, however, it is structurally insufficient – regardless of how good the nursery is.
The Swiss labour Force Survey shows how large this minority is. Around 16 per cent of employees work regularly in the evenings, a good 5 per cent at night, 26.5 per cent on Saturdays and almost 16 per cent on Sundays. In individual sectors the figures are far higher: in the health and social services sector, 12 per cent regularly work at night, and in the transport and warehousing sector, 22 per cent. In addition, there are around 5 per cent of on-call employees whose assignment is fixed at short notice.
For these families, nanny or nursery is not really an either-or question. It is: how do we cover the hours that no institutional service provides?
There are three other situations in which a nanny's flexibility makes a difference that no extension of opening hours can replace.
A mildly unwell child. Nurseries have exclusion policies for good reason – fever, vomiting and infectious illnesses. A child with a temperature of 38.2°C and a cold stays at home. A nanny can continue caring for them there; a nursery cannot. During the first year of childcare, when eight to twelve days of illness are realistic, this is the point at which arrangements most often come under strain.
The transition to Kindergarten. The question of flexibility does not disappear with the fourth birthday, it shifts. Kindergarten block times only cover part of the day, afternoons are regulated differently depending on the municipality, and school holidays cover thirteen weeks a year. Anyone who has a nanny carries this structure through Kindergarten entry.
The unplanned weeks. A project, a business trip, a hospital stay in the family: a nanny can be used differently at short notice. A care contract with fixed days is not.
Attention
Flexibility is a service, not a quality. It is provided by one person – and it must be contractually regulated, otherwise a conflict will arise.
It is important to know that the Employment Act does not apply to employees in private households. Maximum working hours, breaks and supplements for evening or weekend work therefore do not follow automatically from that Act; they must be set out in the employment contract. Agree in writing on maximum daily hours, notice for short-notice assignments, compensation for evening and weekend work, and overtime. In practice, leaving these matters open is more likely to cost you a nanny through exhaustion than through a better offer elsewhere.
One nanny is paid per family, one nursery per child. This is the only point at which the cost calculation is completely reversed – and it does so from the second and at the latest from the third child.
The effect is purely mathematical: For a child, a full-time nursery place of around CHF 2,800 gross is compared to a nanny with full costs of around CHF 6,000. For two children, both models are about the same, but for three children the nanny is clearly cheaper. You can find the detailed list in the cost section below.
Two qualifications are important and routinely omitted from the calculation. First, many nurseries offer sibling discounts. Second – and more significantly – subsidies and childcare vouchers are calculated per child. The support therefore increases with each child, while it remains zero for a nanny. Depending on income, that can shift the break-even point by an entire additional child.
In addition to the bill, there is an organisational advantage that parents with several children usually value more than the money: one drop-off and pick-up location instead of two, one case of illness instead of two, one holiday calendar instead of two. For children of different ages – an infant and a Kindergarten child, for example – transitions and travel times quickly add up to several hours per week.
The educational picture is mixed, and honesty helps. Siblings of different ages at home bring real benefits: the older child consolidates knowledge by explaining, while the younger learns by imitating a model who is closer to them than any adult. What is missing is contact with children of the same age – and that is not equivalent. A four-year-old needs other four-year-olds with whom to compete, negotiate and work out rules. A two-year-old sibling cannot replace that.
Tip
Calculate the break-even with subsidies, not without them. The obvious calculation “nursery rate multiplied by number of children against nanny wages” is regularly misleading because it excludes the relief that accrues per child.
So get the calculation first in your community for all children and only then compare. And calculate the full costs for the nanny – gross wages plus around 15 to 20 per cent employer contributions plus holiday cover.
The nanny's limits are of a structural nature: no second adult in the room, no regulatory oversight, no quality specifications, a complete risk of failure with a single person and no natural everyday life with peers.
These points have nothing to do with the quality of a single person. They follow from the model itself and remain in place even if you find the best nanny in town.
In a nursery, several adults work with the children at the same time. That provides mutual oversight, professional challenge and, in an emergency, a second pair of eyes. In a family home, the nanny is alone – for eight, nine or ten hours a day – with a child who may not yet be able to explain coherently what has happened.
This is not a vote of no confidence in nannies. It is a statement about the structure of oversight. The same logic also works in reverse: a nanny who is overwhelmed, having a difficult day or unsure how to respond has no colleague to step in or offer professional challenge.
Attention
There is no approval process for hiring a nanny in your own household. Nobody checks the qualifications, nobody demands an educational concept, a protection concept or a security concept, nobody comes by to check.
For an approved nursery, all of this is a prerequisite for operation, and compliance is checked periodically. If you choose a nanny, you take on these functions yourself – including a special private criminal-record extract from the criminal record, reference interviews with previous families and clear written agreements on sleep, nutrition, screen time and emergencies.
If the nanny is ill, resigns or takes a holiday, the family's entire childcare arrangement becomes unavailable at once. This is not a small gap but a complete loss of cover. During any period of continued salary payments, the family may also pay twice: the nanny's ongoing salary and the cost of replacement childcare.
There is also a second, more long-term effect. Attachment security increases with the duration of the relationship. If the nanny changes after eighteen months – which is often the case in this job market – the setup starts all over again. A child who experiences three nannies in four years has less relationship continuity than a child in a nursery with a stable team.
This is the most important point in terms of content, and it is often refuted with reference to playgroups and toddler meetings. That falls short, and for a measurable reason.
The mechanism is simple, which is precisely why it works: a two-year-old trying to explain something to another two-year-old has to communicate more clearly than with an adult who can already infer what they mean. There is good evidence that this pressure has measurable effects on language development; the relevant studies appear in the section on language and early learning below.
The decisive factor is the dose: two hours of playgroup per week does not create this density. Anyone who is cared for at home should therefore plan contact with their peers as an integral part of the week, not as an occasional addition.
There is very little robust international research on nanny care as such. The reason is straightforward: the group is too small to produce substantial study samples. Researchers have examined related arrangements – childminders and care by relatives – but those findings transfer only to a limited extent.
The Zurich z-proso study offers at least some pointers. It followed around 1,300 children in the city of Zurich from school entry to age twenty and retrospectively recorded their childcare before Kindergarten. Two findings matter for the nanny question.
First: Among children cared for by a childminder for an average of more than about three days a week, teachers reported more externalising behaviour between ages nine and thirteen – including aggression, non-aggressive problem behaviour and ADHD symptoms. One explanation the authors consider plausible is that the peer mechanism has limited scope in small home-based settings with few children, leaving the adult–child relationship as the more likely explanatory factor.
Secondly: When cared for by family members – i.e. in the classic grandparent model – there was below-average school performance between the ages of nine and eleven and a below-average probability of later attending high school. The authors suspect that family members provide less cognitive stimulation on average – but they themselves point out that this form of care in their sample was associated with less parental education and the causality therefore remains open.
Neither finding is an argument against a good nanny. They are arguments for making cognitive stimulation and peer contact an active part of home-based childcare instead of assuming that they will happen by themselves.
A nursery offers qualified staff working as a team, a binding educational approach under regulatory oversight, daily contact with peers, measurable long-term language and educational benefits, and trained eyes that spot developmental concerns earlier than the family environment may do.
The strongest body of evidence comes from the NICHD Study of Early Child Care and Youth Development, a longitudinal study of 1,261 children who were followed from birth and assessed at 15, 24, 36 and 54 months.
Three central findings emerged. First: high-quality care predicted stronger cognitive, language and pre-academic outcomes at every assessment age, regardless of the form of childcare. Second: time in institutional group care additionally predicted stronger language and cognitive scores and greater readiness for school compared with other arrangements of equal quality. Third: in every analysis, parents had a substantially greater influence than the form of childcare. Anyone asking whether a nanny or nursery ‘shapes’ the child systematically underestimates their own contribution.
The second major body of evidence comes from England and may be even more useful to parents because it asks not only whether early-years education has an effect, but which kind. The EPPE study followed more than 3,000 children across 141 settings run by a wide range of providers. Quality was not self-reported; it was assessed through full-day observations using standardised instruments that recorded adult–child interactions and provision in language, mathematics and science, among other areas.
Four findings from the study continue to shape professional debate:
In numbers
More than 3,000 children, 141 settings, followed from age three to sixteen. EPPE is Europe's largest longitudinal study of early-years provision – and its most important message for parents is simple: part-time is enough; quality is not optional.
The benefits were particularly marked among children considered at risk of developmental difficulties. For them, a high-quality setting acted as a protective factor, and fewer were later identified as having special educational needs in primary school.
For the question of nanny or nursery, this leads to a refreshingly pragmatic conclusion: if you find a good setting, your child does not need to attend five days a week to benefit. If the setting is poor, five days will not make it effective.
A supplementary NICHD analysis examined what happened when groups actually met the recommended standards for staff-to-child ratios, group size, qualifications and professional development. The findings are directly useful when choosing a nursery.
In numbers
Every standard that is met has an impact – there is no threshold value. The more of the four standards a group met, the better their language comprehension and readiness for school were and the lower the behavioural problems at 36 months.
The starting point was sobering: depending on the children's age, only 10 to 34 per cent of the observed groups met all four standards. At 24 months, the staff-to-child ratio was the strongest predictor; at 36 months, staff qualifications mattered most.

Why exactly these four factors? Because each of them works in a different place and because they cannot replace each other.
The staff-to-child ratio determines how often a practitioner can respond to one child rather than only to the group. It matters most for the youngest children, because babies and toddlers need physical closeness that cannot be provided in parallel – changing nappies, feeding and comforting are one-to-one tasks. The sector association kibesuisse therefore deliberately avoids rigid group-size rules in its guidelines and focuses on the adult-to-child ratio: the younger the children, the fewer each practitioner should be responsible for.
Group size has an independent effect. Twelve children with four practitioners have the same ratio as six children with two, but a markedly higher noise level, more social demands and more transitions during the day. For children who are sensitive to stimulation, absolute group size often matters more than the ratio.
Qualifications become more important as children get older and the emphasis shifts from care to education. From around age three, language development, support with conflict and preparation for structured learning come to the fore – skills that require training, not experience alone.
Professional development is the easiest factor to check, yet parents almost never ask about it. It reveals whether a setting budgets for staff development or merely administers it.
A fifth factor does not appear in standard checklists but belongs there: staff turnover. Attachment security grows with the length of the relationship. A team may be exceptionally well qualified, but if half its members change every year, continuity is still lost.
This leads to perhaps the most useful question on any visit: not ‘Is this a good nursery?’, but ‘How many of these factors are present in the specific group my child would join?’
This advantage is rarely mentioned and in individual cases is the most consequential of all.
Parents see their child every day, but without a point of comparison. A qualified practitioner who has worked with children of the same age for years has that reference point and notices differences sooner. This applies to language, fine and gross motor skills, hearing, sight, attention regulation and social behaviour. In a group, it stands out when a child does not respond to their name from behind. At home, it may be put down to concentration.
The EPPE data support this: children who had attended a high-quality setting were less likely to be identified later in primary school as having special educational needs. One plausible mechanism is not only the support itself, but earlier access to assessment and specialist help.
In practice, a nursery that observes and documents development systematically can shorten the route to speech and language therapy, occupational therapy or a hearing assessment by months. For language concerns, that time saving matters because intervention generally becomes less effective with age.
Practical tip
Ask how observation is carried out – and what follows from it. Is there structured development observation? Is it documented? Are there regular development discussions and at what frequency?
The crucial follow-up is: what happens when staff notice a concern? Who speaks to the parents, how quickly, and does the setting know how to refer families to the appropriate specialist services? A digital portfolio is useful; a clear pathway when concerns arise is more important.
The fundamental difference between nursery and nanny is not the building, but the organisational form. A nursery is a system with redundancy – and redundancy is not inefficiency in everyday care, but rather the prerequisite for reliability.
Absences are covered internally. If one practitioner is unavailable, another who knows the child, understands their signals and is familiar with their routine takes over. For the family, nothing changes. With one individual, everything does.
There is professional challenge and support. Several adults in the room can observe one another, give feedback and provide a second pair of eyes in an emergency. A practitioner can also be relieved on a difficult day before exhaustion turns into impatience. Case discussions, team meetings and supervision formalise this support.
The attachment dynamic is different – and this is a separate finding. The meta-analysis by Ahnert, Pinquart and Lamb found that, in group settings, attachment security was predicted not by sensitivity towards one individual child but by group-related sensitivity: the ability to read and guide the group as a whole without allowing any child to be overlooked. That is a learned professional skill – and one that a person caring for a child alone at home is never required to demonstrate, because there is no group to manage.
Children form relationships with several adults. At nursery, a child has a key person but also knows the rest of the team. From a developmental perspective, these multiple attachments are not problematic; they provide a safety net in daily life. A staffing change does not mean losing the only trusted adult outside the family.
The concept outlives the people. What applies in a setting – how conflicts, the pain of separation, eating or sleeping are dealt with – is not up to the day's discretion. It is recorded in writing, is part of the approval and is part of the training of new employees.
This is less romantic than the idea of a single familiar person. But it is what sustains a care arrangement for years.
The transition to Kindergarten requires skills that have little to do with knowledge: being able to wait your turn; follow an instruction addressed to everyone; endure a conflict without immediate adult intervention; orient yourself in a room with twenty children.
This self-regulation does not come from explanation, but from practice – and it needs a group. This is exactly what the NICHD finding on higher readiness for school with institutional care means, and this is exactly what the EPPE finding on more independence, concentration and sociability at an earlier age is also aimed at.
For children cared for exclusively at home until they start Kindergarten, the transition can be the real test – socially rather than academically. That is not an argument against home-based care. It is an argument for making group contact a regular part of the week by the year before Kindergarten at the latest.
This point belongs in an honest comparison, even if it is not about the child.
A nursery place can be planned: fixed days, fixed costs, known closing times, no employer role, no payroll, no search for a replacement. The z-proso authors even consider it to be the most likely explanation of their own findings that the school advantage of nursery children comes less from the nursery itself than from the parents' improved professional and financial situation – and the support that this makes possible at home.
There is also a softer but genuine benefit: parents at a nursery meet other parents. For newcomers without family nearby – common in Zurich and Zug rather than exceptional – this is often their first social anchor in a new place. A nanny may offer a great deal, but does not automatically connect a family with other local families.
The type of care at the nursery is less important than how it is carried out. Three factors make the difference: the quality of care, how you deal with the infection phase at the beginning and how opening times and holiday arrangements fit into everyday family life. The fourth – the scope of care – is dealt with in the next chapter.
Unlike the nanny, the nursery's weak points are not structurally insoluble – they depend on how a setting is run and how you use the space. That's exactly why it's worth knowing them: each of these points can be checked when making your selection.
The sentence “nursery is better” is worthless because it ignores the crucial variable. The NICHD standard analysis has shown what quality has in concrete terms: The more of the four standards – staff-to-child ratio, group size, training, further education – a group met, the better the language comprehension and readiness for school were and the fewer the behavioural problems.
An honest assessment must acknowledge that quality varies across Switzerland. A study by Simoni and Seiler-Wurstmann found predominantly middling quality in Swiss nurseries; around one in four of the groups assessed achieved only minimal quality. Sonja Perren and her team confirmed substantial variation in a broader survey. Surveys by Savoirsocial also suggest that around half of nursery staff in German-speaking Switzerland have no completed qualification in the care sector.
This is not an argument against nurseries; it is an argument for examining the specific setting closely. Providers that consistently use qualified staff, small groups and stable teams sit well above this average. The range simply means that the difference between a good and an average nursery is greater than the difference between nursery and nanny as categories.
Practical tip
Ask about the specific group, not the company. “We employ trained qualified staff” is not information. The question is: How many people work in my child's group, what training do they have and how long have they been here?
Ask additionally what happens if they are sick. Does the management step in? Are there permanent representatives? Or will groups be merged? The answer to this second question says more about everyday life than any concept paper.
It is undisputed that nursery children are initially sick more often. The good news is in the distribution.
The Dutch WHISTLER cohort followed 2,217 children to age six. Across the full six years, the overall rate of medically diagnosed respiratory and middle-ear infections differed little between children who attended nursery and those who did not. The timing did differ: more episodes before the first birthday, fewer after the fourth. The infection burden therefore shifts earlier, to a stage when parents may have more flexibility at work than they do when a child starts Kindergarten.
For the sake of completeness: A large Danish registry study found the same increase after entry, but no measurable protective effect for later childhood. The data is ambiguous at this point – only the initial phase is undisputed.
Briefly explains
What this means for your planning. Realistically, allow for days when your child cannot attend during the first year at nursery. A practical rule of thumb is eight to twelve days of illness, and potentially more if the child starts before their first birthday.
Clarify in advance who will take over these days. This is the most common reason why care arrangements fail in the first six months – not the nursery, but the lack of an answer to the question of who stays at home on Tuesday morning.
nurseries typically open between 7 a.m. and 7:30 a.m. and close between 6 and 6:30 p.m. This is enough for most work models – if you have regular evening appointments, you need a supplementary solution.
Second point: the holiday regulations. Some settings close during company holidays, others provide care all year round. Both have their logic – company holidays make team planning easier, year-round care relieves the burden on parents without grandparents nearby. It is crucial that you know the rules before you plan your own holiday.
Third point: Waiting lists of six to eighteen months are normal in cities. If you only start looking after birth, you may be looking too late. A non-binding pre-registration during pregnancy usually costs nothing.
This principle applies to both models. The following sections address the questions that matter regardless of the arrangement and that determine outcomes in practice: the amount of childcare, language, safety, money and legal responsibilities.
Across many studies, the amount of childcare explains the strongest effects more often than the type of childcare. The two interact: the greater the amount, the more heavily the outcome depends on the quality of the setting.
The question nanny or nursery is usually framed as an either-or choice. Research suggests that the more important question is how much. Almost every comparison overlooks this point, even though it explains more than the choice of model.
The z-proso study found a remarkable trend in educational level at the age of twenty. Children who attended one and a half to two days of nursery per week had the highest level of education – higher than those who did not attend nursery, but also higher than those who attended more than two to three days per week. So it is not a linear relationship, but rather an inverted U-curve with an optimum in the middle range.
This is contrasted by another Swiss finding that is often overlooked. A Zurich study by Bleiker and colleagues compared 637 children between the ages of eighteen and twenty-four months who were cared for either exclusively in the family or in a nursery on at least two days a week. The two groups did not differ in motor, cognitive, linguistic and social skills – with an overall high quality of care.
The cortisol findings already described fit into the same picture: What stimulates also causes strain. What is revealing is that the afternoon increase did not occur in those settings that were of higher quality – measured in terms of the sensitivity of the carers and the noise level. It is not the group that creates the stress, but rather a group under unfavourable conditions.
For behavioural outcomes, the relationship is linear: the more days of childcare, the higher the scores for externalising symptoms reported by parents. Importantly, this is not confined to institutions. Where children spent around three or more days a week with childminders, teachers also reported more problem behaviour. The amount of childcare therefore has an effect independently of its form.
Scope of care | What the data suggests | Practical classification |
|---|---|---|
0 days | No peer contact; on average, lower level of education at 20 than at medium level | Peer contact must be actively organised |
1–2 days | Optimal level of education at 20; low behavioural effects | Ideal if professionally feasible |
3 days | Solid peer contact; behavioural effects increase measurably | Good compromise for dual earners |
4–5 days | Clearest connection with behavioural values; Quality of care was not recorded in this data | The reality for many families – quality, the length of the day and consistent carers matter particularly strongly at this level |

The childcare took place between 1997 and 2002, when Zurich's nursery sector was still developing and neither staff-to-child ratios nor qualification standards matched today's. Most importantly, the researchers had no information about the quality of care and explicitly note that this gap could change the interpretation of their findings. Other research shows that children in very high-quality settings display fewer externalising behaviours than those in average-quality settings.
The table does not tell us what happens across five days in an exceptionally well-run group. It shows that as the amount of childcare rises, quality, the length of the day and continuity of relationships matter more. If you need four or five days – as many families do – examine those factors more closely rather than forgoing childcare.
An economic study from Norway adds an aspect to the picture that is rarely discussed. Havnes and Mogstad analysed the expansion of subsidised childcare in the 1970s and its effect on later income. Children from low-income families benefited significantly; Children from high-income families performed worse. A Canadian study of the subsidy reform in Quebec found similar patterns and additional long-term unfavourable relationships up to adolescence.
The conclusion is neither ‘nursery is good’ nor ‘nursery is bad’. The benefits of institutional childcare are greatest when it provides something missing at home, and smallest when the home environment is already highly stimulating. For well-educated parents with time available, a moderate amount of high-quality childcare is probably the most favourable combination.
Attention
An important caveat to all of these numbers. All studies in this field – internationally as well as in Switzerland – are based on observational data, not on experiments. Families who choose a nursery differ systematically from families who do not.
The researchers control for many of these differences, but never for all of them. The authors of the z-proso study expressly emphasise that their findings cannot be interpreted causally, or only very carefully – and that they completely lacked information on the quality of care. Anyone who tells you that nursery “makes” children aggressive has not read the studies.
Tip
Think in days, not models. The most useful question is not ‘Nanny or nursery?’, but ‘How many group days does our child need – and how will we cover the rest?’
If you have a choice, two or three nursery days combined with time at home or a part-time nanny is a sound balance. If you do not have a choice, reframe the question: the decisive factors are no longer the number of days, but the staff-to-child ratio, team stability and whether your child can be collected earlier on some days.
A nanny provides intensive one-to-one language input; a nursery provides linguistic variety through adult language, peer language and group situations. Research shows that the language ability of the peer group influences each child's development, with the greatest benefit for children whose own language skills are weaker.
In a one-on-one situation, an adult speaks more words directly to a child. This is a real advantage, especially in the second year of life. What is missing in this situation is the compulsion to reach an understanding between unequal people – and this is an independent development factor, not a side effect.
Laura Justice and colleagues studied 338 children in 49 preschool groups to test whether a child's language development varied with the language abilities of their peers. It did – and the effect was strongest for children whose own language skills were relatively weak and who joined groups with stronger speakers. Mashburn and colleagues found the same pattern: the group's average vocabulary predicted each child's vocabulary growth even after family background and practitioner characteristics were taken into account.
A practical tip from this that is rarely formulated: If your child is behind in language, a group with children who are more linguistically strong is more effective than additional individual attention. In both studies, the effect was greatest in this constellation.
The two models diverge more clearly when it comes to multilingualism. An English-speaking nanny can provide a great deal of input, but they remain one person in an otherwise German-speaking environment, and that input ends with the employment relationship. If a child loses an English-speaking nanny at age three, they often lose a substantial part of the language exposure they had built up as well.
A consistently bilingual setting, by contrast, can use the immersion principle: each practitioner speaks one language consistently, enabling the child to organise both systems and learn them alongside one another rather than in a mixture. The advantage lies not in the label, but in the redundancy – the language is not dependent on one person.
Definition
What does ‘One Person – One Language’ mean? Each key person speaks to the child consistently in one language. The child associates language with the person rather than the situation and can develop two separate, stable language systems.
The decisive factor is the consequence: If the same person constantly switches between languages, the ordering effect is lost. This is precisely why bilingualism is easier to maintain in institutional settings than in private settings – where it is part of the personnel concept. The Little Star Day School, for example, has been running its groups in Zurich, Kilchberg and Zug according to this principle in German and English since 2001.
Nurseries require cantonal authorisation under the Foster Children Ordinance. They must submit educational, safety and safeguarding policies and are inspected periodically. There is no equivalent regulatory vetting for a nanny; parents carry the full responsibility.

The staff-to-child ratio is the single most informative figure – and the NICHD standards analysis shows why. At 24 months, it was the strongest individual predictor of children's development. The sector association kibesuisse deliberately avoids rigid group sizes in its guidelines and instead centres the adult-to-child ratio. The principle is simple: the younger the children, the fewer each practitioner should be responsible for.
A full-time nanny in Switzerland costs around CHF 4,500 to 7,500 per month including employer contributions. A full-time nursery place costs CHF 2,200 to 3,000 gross per month, with day rates between CHF 110 and 150 – before subsidies and tax deductions.
The legal basis is the federal government's standard housekeeping employment contract. On December 5, 2025, the Federal Council extended it until the end of 2028 and increased the minimum wage by two per cent as of January 1, 2026. It applies throughout Switzerland except in the canton of Geneva, which has its own, higher minimum wage.
Category | Minimum wage per hour (from January 1st, 2026) |
|---|---|
Unskilled | CHF 20.35 |
Unqualified, with at least four years' professional experience | CHF 22.30 |
Qualified with an EBA (two-year basic vocational qualification) | CHF 22.30 |
Qualified with an EFZ (three-year basic vocational qualification) | CHF 24.55 |
Source: SECO, information on the Standard Employment Contract for Domestic Workers, as at 1 January 2026. Holiday pay is additional.
Two qualifications matter. First, the Standard Employment Contract for Domestic Workers does not necessarily apply where a nanny provides childcare only. If the role also includes domestic work covered by the standard contract – such as cleaning, laundry, shopping or cooking – its provisions apply to the entire employment relationship. Second, the minimum wage is a floor, not the market rate. In Zurich and Zug, agreed pay is usually considerably higher, typically CHF 26 to 35 an hour or CHF 4,000 to 6,500 gross per month for full-time work.
The employer's contributions are added to the gross wage: AHV/IV/EO, ALV, family compensation fund and accident insurance add up to around 15 per cent. From an annual salary of CHF 22,680 (as of 2026), occupational pension provision is added. In total, the actual costs are 15 to 20 per cent higher than the gross wage.
Calculation example
One child, full-time care, Zurich area
By comparison:
Not included in the nanny bill: holiday replacement, continued salary payments in the event of illness, recruitment costs when changing, any placement fees.
The unromantic answer is: with two or three children. A nanny is paid per family and nursery fees are charged per child, so the calculation shifts with every additional child.
Constellation | nursery (gross, before subsidies) | Nanny (full costs) | Tendency |
|---|---|---|---|
1 child, 5 days | approx. CHF 2,800 | approx. CHF 6,100 | nursery significantly cheaper |
2 children, 5 days | approx. CHF 5,600 | approx. CHF 6,100 | Around the same |
3 children, 5 days | approx. CHF 8,400 | approx. CHF 6,500 | Nanny cheaper |
1 child, 3 days | approx. CHF 1,700 | approx. CHF 4,000 (60%) | nursery significantly cheaper |
Reference values for the greater Zurich/Zug area, without subsidies and tax effects. Individual differences are significant.
Two corrections to this: Subsidies and childcare vouchers significantly reduce the nursery fee – the nanny costs remain unchanged. And sibling discounts at many nurseries postpone the two-child bill again.
Common error
The nanny is almost always calculated too cheaply. The typical calculation error: hourly wage times weekly hours, compared to the nursery rate. There are three items missing from this calculation, which together quickly add up to 1,500 francs per month.
Firstly, the employer contributions of 15 to 20 per cent. Secondly, the paid holiday weeks, during which a replacement is also necessary. Thirdly, the lost subsidy that only exists for institutional care. Therefore, calculate full costs against full costs – and obtain your community's contribution calculation beforehand.
When comparing nurseries, look carefully at what the day rate does not include. Are nappies charged separately? Must families supply baby food? Are outings, projects or the settling-in period extra? Is there a registration or reservation fee, and precisely what does it cover? Numerous small charges can raise the monthly total considerably. Providers with an all-inclusive model – Little Star Day School, for example, includes meals, nappies, care products and developmental activities in its fee – may look more expensive initially but are often easier to budget for.
For the nanny, there are other items: holiday replacement, professional development, meals during working hours, any expenses and, in the event of a separation, continued salary payments during the notice period.
Childcare vouchers and the new federal childcare allowance apply only to institutional childcare. Families employing a nanny receive neither. Both forms of childcare can, however, be tax-deductible – in the case of a nanny, only where the employment is properly registered.
On December 19, 2025, Parliament passed the Federal Act on the Support of Institutional Family-Supplementary childcare (UKibeG) as an indirect counter-proposal to the nursery initiative. After the initiative committee conditionally withdrew its popular initiative in March 2026, the referendum deadline expired on July 2, 2026 without a referendum being held. The law is therefore considered passed.
It provides a care allowance according to the Family Allowance Act: at least CHF 100 per month for one day of care per week, CHF 50 more for each additional half day of care, a maximum of CHF 500 per child per month up to the age of eight. Parents who are employed or in training are entitled to this. According to the umbrella organisation Alliance F, the payment is not expected until the end of 2029 at the earliest.
Attention
The childcare allowance is only available for nurseries and nursery families. Parents who look after their child at home, give it to grandparents or hire a nanny will not receive the new allowance.
The same applies to municipal subsidies and cantonal childcare vouchers: they are tied to recognised or licensed settings. In the city of Zurich, a nursery needs a subsidy agreement; in the city of Zug, it must be a recognised nursery within the canton. A nanny is not eligible under any of these schemes.
From a tax perspective, the picture is more favourable. Since the 2023 reform, third-party childcare costs of up to around CHF 25,500 per child per year have been deductible for direct federal tax purposes (2026 figure); cantonal limits vary considerably. Nursery, out-of-school care and childminder costs are deductible, as are the costs of a nanny or au pair, provided the person is formally employed and pay and social-security contributions are accounted for correctly. The childcare must be necessary because of employment, education or incapacity for work, and the child must be under fourteen.
Tip
Enclose the wage statement. If the care is provided by someone you employ, several cantons – including Zurich – require a copy of the issued wage statement with the tax return.
Undeclared work makes the deduction impossible and is also a criminal offence. A properly registered nanny costs more, but it is the only arrangement under which any of the cost can be reclaimed.
If you hire a nanny, you legally become an employer. You must register with the AHV compensation office from the first franc of pay, take out compulsory accident insurance, issue monthly payslips and an annual salary certificate, and enrol the nanny in an occupational pension scheme once annual pay reaches CHF 22,680.
Many families underestimate this role. It is not complicated, but the obligations are binding – and there is no de minimis threshold. All paid work in a private household is subject to AHV contributions, regardless of the amount earned.
How to proceed
Six steps for correctly hiring a nanny
Employment-law duties under the Code of Obligations also apply: continued salary payments during illness or accident, at least four weeks of paid holiday, and protection from dismissal during statutory protected periods.
A nanny may suit a family with irregular working hours, three or more children, additional care needs or very short childcare windows. A nursery may suit a family with predictable working patterns, one or two children, and a strong focus on social development and preparation for school.
The following overview is not a scorecard on which the side with the most ticks wins. The rows do not carry equal weight. Some are hard constraints that may rule out one option in practice, such as irregular working hours or whether you want to become an employer. Others are preferences that can change. Read the table in that order: first identify any non-negotiable conditions, then weigh up the rest.
Your situation | More like a nanny | More like a nursery |
|---|---|---|
Irregular or late working hours | ✓ | |
Planned workload, 2-4 fixed days | ✓ | |
One child | ✓ | |
Three or more children under six | ✓ | |
Child with increased care needs | ✓ | depending on the concept |
Pronounced sensitivity to stimuli | ✓ | in small groups ✓ |
Linguistic backlog | ✓ | |
Bilingualism as a goal | ✓ | |
Preparation for Kindergarten and school | ✓ | |
Claim for Subsidies or vouchers | ✓ | |
No desire for employer role | ✓ | |
Frequent travel by both parents | ✓ |
Four lines deserve a short explanation because they are not self-explanatory.
Additional care needs include chronic illness, premature birth or a diagnosed developmental delay. A nanny is not automatically the better choice; what matters is whether a setting has the staff and approach needed to support the child. Ask specifically about experience of comparable situations.
Marked sensitivity to stimulation may favour home-based care in the short term because it removes the noise and density of a group. In the medium term, a small, calmly run group may be better because the child learns to manage stimulation rather than avoid it. Here, group size matters more than the staff-to-child ratio.
A language delay is the clearest row in the entire table: a group containing children with stronger language skills has a demonstrably greater effect than additional one-to-one attention.
Eligibility for subsidies is often underestimated because many parents assume their income is too high. A calculation from your municipality costs nothing – obtain one before deciding.
An observation from practice that is rarely found in guides: For many families, the answer to the question is different over time than at the beginning. In the first year of life, rest is important – and cortisol research confirms this intuition because the effect is strongest in the youngest children. From around eighteen months onwards, many children's needs noticeably shift towards their peers. Anyone who defines the model once and never checks it again misses this turning point.
Many families combine nursery with additional private childcare: two or three nursery days for peers and learning, plus a part-time nanny for hours outside nursery opening times, holidays and days when the child is ill. This also matches the amount of childcare associated with the most favourable long-term outcomes.
In practice, the choice is less often a pure either-or than the title of this article suggests. In Zurich and Zug, mixed arrangements are now more common than relying solely on a nanny – and they address the greatest weakness of each model at the same time: a nursery's fixed hours and the risk of relying on one individual. Three combinations are particularly common.
Nursery plus a part-time nanny for the hours at either end of the day. The nursery covers the core of the day; a person on a small contract covers early mornings or late evenings. It is the least expensive combination because the private hours remain limited, and it solves precisely the problem that nursery alone cannot address.
Nursery plus grandparents. Two or three days in nursery, one or two with family. This is common, inexpensive and valuable for attachment. Be realistic about grandparents' capacity and do not assume that they will always be available.
Nursery plus an au pair. This can be attractive with two or more children and irregular hours. Bear in mind that an au pair has no early-years qualification and generally stays for no more than a year – viable as a supplement, but not as the main carer for a young child.
The following overview shows the entire field from which such combinations can be made up.
Type of care | Guideline costs | Strengths | Weaknesses |
|---|---|---|---|
Day care centre / crèche | CHF 110-150 per day | Team, supervision, peer group, support concept | Fixed times, waiting lists, infections |
Nanny | CHF 26-35 per hour gross | Flexibility, 1:1, low stimulus density | Costs, risk of failure, no supervision |
Childminder / family day care | CHF 6-10 per hour per child | Small group, family setting | No cover if the childminder is ill |
Au pair | CHF 500-800 net plus food, accommodation, language course | Inexpensive, culturally enriching | No early-years qualification, high turnover |
Grandparents | mostly free of charge | bonding, trust, continuity | no childcare allowance, resilience |
play group | CHF 10-20 per morning | Peer contact in small doses | No substitute for care during working hours |
A word of caution: combining does not simply mean adding more. Every additional carer creates another transition in the child's day and another set of arrangements in yours. Two reliable forms of childcare generally work better than four flexible ones, particularly for children under two, for whom every change requires adjustment.
For a nursery, check the staff-to-child ratio, the qualifications within your child's actual group, staff stability, cover arrangements and transparent pricing. For a nanny, check qualifications, the special private criminal-record extract, references from previous families and your contingency plan for days when the nanny is unavailable.

Twelve questions that make everyday life visible
It is worth pressing for specifics on question 7. If a team can immediately give concrete examples of the language they use, the approach is embedded in everyday practice. If you hear only generalities, there is usually no real concept behind them.
Nanny selection checklist
Ten points that you have to check yourself
Either can be good. Research indicates that quality matters more than the form of childcare. Nursery has structural advantages for language, social development and preparation for school; a nanny offers flexibility and lower levels of stimulation.
If you have a choice, two or three days is a good balance: enough contact with peers without an excessive weekly load. With four or five days, the number itself matters less than the quality of the group, the length of each day and the consistency of the key persons.
nurseries generally accept children from three to six months old. Between twelve and eighteen months, interest in peers increases significantly, and the stress reaction to group settings is lower than in infants.
No. Some studies find slightly higher scores where children attend for many hours, but the differences are explicitly below any level of clinical concern. The effect largely disappears in very high-quality settings, and the observational data do not in any case permit a causal interpretation.
Almost always for a child. A full-time nanny costs around CHF 5,000 to 7,500 per month including employer contributions, while a full-time nursery place costs CHF 2,200 to 3,000 gross. Once you have three children, the relationship is reversed.
No. Municipal subsidies and cantonal care vouchers are tied to recognised institutions. The new federal childcare allowance according to UKibeG also applies exclusively to institutional care and childminders.
Yes, provided the nanny is officially employed and you account for wages and social security contributions correctly. The maximum deduction for direct federal tax in 2026 is around CHF 25,500 per child; Cantonal amounts vary.
Registration with the AHV compensation fund from the first franc paid, compulsory accident insurance, monthly payslip, annual salary statement and from an annual salary of CHF 22,680, connection to a BVG pension scheme.
If there is additional housework, the NAV housekeeping applies: since January 1, 2026 CHF 20.35 per hour unskilled up to CHF 24.55 with EFZ. Average market wages in Zurich and Zug are significantly higher.
The quality of the attachment with parents depends primarily on parental sensitivity. One study showed that attachments remained secure or became secure when parents spent more days settling in.
Two to four weeks, with stays becoming gradually longer, is typical. Children who have previously been cared for exclusively at home may need six weeks. Research shows that the number of days for which parents accompany the transition affects attachment security.
The cortisol level rises more in the group than at home – a normal adaptive reaction to a more stimulating environment. Studies have shown that this increase did not occur in settings with high quality and low noise levels.
Yes, especially in the first year. A Dutch cohort of 2,217 children found similar overall rates over six years, but a shift: more infections before the first birthday, fewer after the fourth birthday.
In the short term, often yes; in the medium term, usually not. Reserved children benefit particularly from a small, stable group with a consistent key person. What matters is a gentle settling-in process, not avoiding the group altogether.
Studies on peer effects show the greatest benefit precisely for children with weaker languages in groups with peers who have stronger language skills. A good group is more reliable than additional individual attention.
Yes, and for many families it is the most stable arrangement. Two or three nursery days provide peers and early learning, while a part-time nanny covers hours outside nursery opening times, holidays and days when the child is ill. This also reduces the nanny costs substantially.
In Zurich and Zug you should register during your pregnancy. Waiting lists of six to eighteen months are normal in urban areas. A non-binding advance registration usually costs nothing.
Nursery and crèche refer to the same model: a licensed setting with qualified staff and groups of children. A childminder looks after a small number of children in their own home – a less expensive and more family-like arrangement, but without a team to cover absences.
There is no universally correct answer to nanny or nursery, and any guide claiming otherwise is selling something. Four narrower questions can, however, be answered.
What does your child need right now? During the first year, often calm and just a few familiar faces – stress research supports that intuition because the physiological response to group settings is strongest among the youngest children. From around eighteen months, most children increasingly need other children, and not only as an occasional organised activity.
How much childcare, rather than which kind? In the long-term data, the amount explains more than the form – and the greater the amount, the more important the quality of the setting becomes. Considering both together is more useful than focusing on the model alone.
What can your system withstand? A nanny is a system with no reserve. A nursery is a system with reserve capacity, but fixed boundaries. Either can be sustainable if you deliberately cover its weak point.
Are you comparing the true costs? Compare full costs with full costs, including employer contributions, holiday cover, lost subsidies and the childcare allowance. With a nanny, the difference between the perceived and actual bill is regularly CHF 1,500 a month.
And then there is a fifth factor that no table can capture: how you feel as you leave the room. Do you feel welcome? Are questions answered openly, including the uncomfortable ones? Can you imagine leaving your child here with confidence?
The most reassuring finding from forty years of childcare research is another one: in every major study, parents had a markedly greater influence than the form of childcare. What you decide at the kitchen table matters. But it matters less than what happens around that kitchen table afterwards.
