The question of age usually comes up when parental leave is ending and a return to work has to be planned. Parents hear conflicting information: one friend sent her child to nursery at six months, another was told that the nursery only takes one-year-olds, and a third read that children can attend nursery until the age of four. All three may be right, because the law only sets the framework, and within that framework each nursery sets its own rules.
This article separates three things that usually get mixed up: what the Polish law says, how individual nurseries apply it in practice, and how a parent can decide when their child is ready for nursery. The legal position described below is as of October 2026, which matters especially for families from abroad who are not familiar with Polish childcare rules.
From what age can a child go to nursery?
A child can start nursery (żłobek) once they have completed their 20th week of life, which is roughly from five months of age. This is set out in Article 7(1) of the Polish Act of 4 February 2011 on the care of children under the age of three. It is the statutory lower limit — no nursery may admit a younger child, but no nursery is obliged to admit children from that age either. Each setting specifies its actual minimum age in its statute.
For comparison: a children’s club (klub dziecięcy), a smaller form of childcare, takes children from the completion of their first year of life (Article 7(2) of the same Act). Preschool covers children from the beginning of the school year in the year in which they turn three, and in particularly justified cases from the age of two and a half (Article 31 of the Polish Education Law).
Age limits in nurseries, children’s clubs and preschools — a table
| Type of care | From what age | Until what age | Legal basis |
|---|---|---|---|
| Nursery (żłobek) | From the completion of the 20th week of life | Until the end of the school year in which the child turns 3 (exceptionally 4) | Act on the care of children under three, Art. 7(1) and Art. 2(3) |
| Children’s club | From the completion of the first year of life | As for nurseries | Ibid., Art. 7(2) and Art. 2(3) |
| Preschool | From the school year in which the child turns 3; exceptionally from 2.5 years | Until the end of the school year in which the child turns 7 | Education Law, Art. 31(1) and (3) |
The table shows the legal limits. The age from which a particular nursery accepts children can be higher than 20 weeks — and often is.
Why do nurseries accept children from different ages?
Because the law leaves them free to choose. Under Article 11 of the Act, a nursery operates on the basis of a statute, and the statute sets out, among other things, the conditions for admitting children. One setting will take a five-month-old baby, another only a child who can already walk, and yet another runs separate groups for babies and for older toddlers.
The decision depends on how the setting is organised. Caring for babies requires different conditions from caring for two-year-olds: places for daytime sleep at different times, meals for children who are only starting to eat solids, and more attention from staff for each child. Some nurseries deliberately focus on children from their first birthday, because such a group can more easily follow a shared daily rhythm.
That is why, before enrolling, it is worth asking directly: from what age do you take children, are the groups divided by age, and until when can a child stay in the nursery? The answer should follow from the statute, which a parent has the right to see.
How to check the rules of a particular nursery
Before signing a contract, a parent can check several things themselves, without relying on a leaflet or a phone call.
Entry in the register. Nurseries and children’s clubs are subject to entry in the register of nurseries and children’s clubs, governed by Chapter 3 of the Act on the care of children under three. The register shows, among other things, the number of places in the setting. The 2026 amendment changes the rules for keeping the register from 2028, but today an entry is the basic confirmation that a setting operates legally as a nursery rather than, for example, as private childcare without supervision.
The statute. This is where the conditions for admitting children are set out, including the minimum age, admission preferences and the rules on fees when a child is absent. The setting should make it available before the contract is signed.
The contract. It is worth checking how long the contract runs, what the notice period is and what happens when a child reaches the end of nursery age during the year — whether they move to a preschool group or the contract simply ends.
Group structure. Asking how many children are in a group and how old they are tells you more than general declarations. A group of children of a similar age works differently from a group that includes both babies and children who are almost three.
Until what age can a child attend nursery?
A child can attend nursery until the end of the school year in which they turn three. If it is impossible or difficult to place the child in preschool — for example because there is no preschool place — nursery care can continue until the end of the school year in which the child turns four. This is set out in Article 2(3) of the Act on the care of children under three.
In this second case, the parent of a child who has turned three submits a statement to the setting about the obstacles to placing the child in preschool (Article 2(4)). In practice this means that a three-year-old in nursery is permissible but exceptional — the default path after the third birthday is preschool.
It is also worth knowing that the Act was amended in 2026 (Journal of Laws 2026, item 1123), and some of the changes come into force in 2027–2028. If you are planning childcare several years ahead, check the current rules before signing a contract.
Nursery for a baby or for a one-year-old — what changes?
The difference between a five-month-old baby and a one-year-old is enormous and affects almost every aspect of the nursery day: sleep, food, movement and the relationship with the carer. A baby needs care adapted to their own changing rhythm, while a one-year-old begins to function within the rhythm of the group. That is why the admission age says a lot about how a setting organises the day.
A baby sleeps several times a day, each according to their own rhythm. They eat meals adapted individually, often still a bottle. They spend most of their time on a mat, on their tummy and back, practising rolling over and sitting up. The carer is above all the person who provides closeness and safety.
A one-year-old walks or is about to, usually has one nap a day and eats the same as the rest of the group, more and more often independently. They are interested in their surroundings and in other children, although they play next to them rather than with them. A group of one-year-olds can follow a shared rhythm: a meal, work, outdoor time, a nap.
That is why in many nurseries, especially those working with the Montessori method, the dividing line is the first birthday. In Montessori education a child in their second and third year learns independence through everyday activities — pouring, tidying up, dressing — and a group in which everyone walks and eats alone offers more opportunities for this. What such a day looks like is described in the article on the Montessori nursery daily schedule.
Montessori education itself distinguishes two stages of early childhood. The group for the youngest, called the Nido, covers babies roughly until they start walking. The next stage is a group of children who already walk, up to about the age of three — in it, independence, speech and movement take up the most space. The two stages have different classroom equipment and a different daily rhythm, which is why a setting that runs only one of them admits children from an age that fits that stage. More about how Montessori divides children into groups, and why it mixes different ages within them, can be found in the article on mixed-age groups in Montessori.
When should you send your child to nursery?
There is no single right moment that suits every family. The law allows a start after the 20th week of life, but the decision depends on the parents’ work situation, the availability of other care — a grandparent, a nanny, extended parental leave — and on the child: their health, daily rhythm and temperament. A good moment is one in which the family has time for a calm settling-in period — admission dates and the enrolment process are covered in when to enrol in nursery in Poland.
A few questions help to structure the decision:
- Does the child have a fairly regular rhythm of sleep and meals? It is then easier for them to adapt to the rhythm of the group.
- Does a parent have time for a calm settling-in period? The first days and weeks at nursery require a parent’s presence and flexibility at work.
- Is the child healthy and up to date with vaccinations? The first months in a group usually mean more infections.
- Is there a lot going on at home right now? The birth of a sibling or a house move is a hard moment for an additional start at nursery.
Settling in and the child’s age
Age also affects how a child gets through the first weeks at nursery. A younger baby usually accepts a new carer more easily, provided the carer offers steady, predictable care. In the second half of the first year many children begin to react more strongly to separation from a parent and to strangers — a natural stage in the development of attachment, not a sign that nursery is a bad idea. One- and two-year-olds understand more, but they also protest more clearly and need time to trust a new place.
Whatever the age, gradually lengthening the time spent there helps: first a short visit with a parent, then increasingly long periods without them, and only at the end a full day with a nap. A fixed goodbye ritual helps too, as does a parent never disappearing without a word. A detailed plan for the first days and weeks is set out in the nursery settling-in guide.
A frequent question is: is earlier or later better? Research on nursery care does not give one answer for all children, and for a parent the quality of the setting matters more than the date — stable staff, a small group, a calm settling-in period. What to look for when choosing is covered in how to choose a Montessori nursery — 12 points.
Moving from nursery to preschool — at 2.5 or at 3
The Polish Education Law allows a child who has reached two and a half to be admitted to preschool, but only in particularly justified cases. As a rule, preschool begins in September of the year in which the child turns three. A child born in December may therefore start preschool at just over two years and eight months, and one born in January at almost three years and eight months.
Non-public settings that run both a nursery and a preschool often arrange a smooth transition around exactly two and a half. At MOC Montessori the nursery takes children from their first birthday to two and a half, and the preschool takes children from two and a half to six: one mixed-age group, the Montessori method and educational continuity under one roof. Details of both stages are on the nursery and preschool pages.
When planning this transition, it is worth keeping the admissions calendar in mind. Children are usually enrolled in public preschools in the spring, for the school year beginning in September, and the dates are set by the municipality. A parent who wants their child to go on to a public preschool after nursery should check the admissions timetable in their municipality several months in advance — otherwise a three-year-old may be left without a place, and the nursery can keep them only under the exception in Article 2(3) of the Act. Non-public settings usually admit children throughout the year if they have places, but it is worth asking early here too, because preschool groups are often full well before September.
For the child, the greatest advantage of this arrangement is the absence of an abrupt change: the same principles, similar materials, a familiar environment. A second settling-in period cannot be avoided entirely, but it is usually shorter and gentler.
Funding and the child’s age
Funding also depends on the child’s age and the type of care. The Aktywnie w żłobku benefit under the Aktywny Rodzic programme is available for children attending a nursery, a children’s club or in the care of a day carer, and amounts to up to 1,500 PLN a month (up to 1,900 PLN for a child with a disability), but no more than the fee the parent pays. It is not available for a child who already attends preschool. The full conditions are described in Aktywnie w żłobku explained, and you can work out your own amount with the Aktywny Rodzic calculator.
This matters when planning the transition: the moment a child moves from nursery to preschool is also the moment this benefit ends. How much a nursery costs in Warsaw and how to calculate the fee after funding is described in the article on Montessori nursery costs in Warsaw.
FAQ — questions about a child’s age at nursery
From how many months can a child go to nursery in Poland? From the completion of the 20th week of life, roughly from five months. This is the statutory limit; a particular nursery may set a higher minimum in its statute, for example the first birthday.
Can a nursery take a one-year-old in the middle of the year? Yes, if it has a free place. Nurseries are not bound by the school year in the way preschools are, and many admit children on a rolling basis when a place in a group becomes free.
Until what age can a child attend nursery? Until the end of the school year in which they turn three. If placing the child in preschool is impossible or difficult, they can stay in nursery until the end of the school year in which they turn four — the parent then submits a statement about the obstacles.
How do a nursery and a children’s club differ in terms of age? A nursery takes children from the 20th week of life, a children’s club from the completion of the first year. Both can provide care up to the same age.
Can a two-and-a-half-year-old go to preschool? Yes, but as an exception — the Education Law allows a child who has reached two and a half to be admitted in particularly justified cases. Non-public settings that run both a nursery and a preschool often arrange the transition at exactly this age.
Does a younger child get ill more often at nursery? In the first months at nursery infections are more frequent regardless of age, because the child is meeting many viruses at once for the first time. It is worth planning backup days of care for this period and talking to the paediatrician about vaccinations before starting.
Does the child’s age affect nursery funding? Indirectly. The Aktywnie w żłobku benefit is available for a child at a nursery, a children’s club or with a day carer, and not for a child at preschool — so moving to preschool ends this support.
In closing
The law sets broad limits: from the fifth month of life to the third, and exceptionally the fourth, birthday. Within those limits each nursery chooses its own rules, and each family its own moment. The best decision takes into account the child’s readiness, the parents’ circumstances and the quality of the setting, not just a date in the calendar. If you have doubts, arrange visits to a few settings and see what the day looks like for children of your child’s age.
