The thing that decides whether nursery waterproofs work is not how waterproof they are. It is how long they take to get onto a two-year-old who does not want to put them on. A key worker dressing ten children for outdoor play is doing the same task ten times, in a cloakroom, against the clock, with children at every stage of cooperation.
That single constraint explains almost every recommendation below, and it is why kit chosen by parents on performance grounds so often gets quietly left on the peg at nursery. This guide is about what works in a setting rather than what works at home.
It applies to day nurseries, preschools, playgroups, childminders and outdoor or forest nurseries. Where those differ, we have said so.
What's on this page
If your child is at school rather than nursery, our guide to forest school waterproofs covers the older end, and the full kit list covers what goes in the bag. Everything below assumes a child roughly between one and four.
Why a nursery is not a smaller school
Four differences change what you should buy.
An adult is doing the dressing. Not the child. Which inverts the usual advice: at school you want a garment a child can manage alone, whereas at nursery you want one an adult can get on and off quickly and repeatedly. Those are different garments.
It happens every day, often twice. The early years framework expects children to have daily access to outdoor play, so this is not an occasional forest school session. Kit is used constantly and wears accordingly.
Children this age have no self-preservation about wet. A four-year-old will sometimes avoid a puddle. A two-year-old will sit in it deliberately, then lie in it. Coverage matters more at this age than at any other.
Everything is shared space. Pegs, cloakrooms, drying arrangements. Kit gets mixed up, and a wet suit hung against another wet suit does not dry.
The result is that a nursery values speed, simplicity and coverage in roughly that order, and performance figures come some way behind. Understanding that makes the rest of this straightforward.
The cloakroom maths
Worth doing the arithmetic, because it is the reason staff have strong opinions about kit.
Take a room of twelve children going outside. If a garment takes two minutes to get on, that is twenty-four minutes of staff time before anyone is outdoors, and the same again coming back in. If it takes one minute, that is twelve. The difference across a week is hours, and it comes directly out of time with the children.
Which is why a garment that is thirty seconds slower is not a minor inconvenience at a nursery. It is the difference between going outside after lunch and deciding there is not time.
The features that cost time are predictable: fiddly fastenings, narrow leg openings that catch on shoes, separates that have to be lined up as pairs, anything that has to be identified from a pile first, and anything a child has learned to resist because it is uncomfortable.
The features that save time: one garment rather than two, a single long zip, generous openings, and something a child recognises as theirs. None of those appear on a specification sheet.
Why one-pieces dominate at this age
Walk into almost any nursery cloakroom and you will find one-piece rainsuits rather than separates. There are three good reasons.
No waist join. Children this age sit, kneel, crawl and lie down constantly, and a two-piece exposes the trouser waistband every time they crouch. Water running down a jacket lands on it and wicks inward. A one-piece removes the problem entirely rather than managing it.
One item, not two. Half the pairs of anything in a nursery cloakroom will be separated by the end of term. A single garment cannot be split up, cannot have one half lost, and cannot be put on in the wrong combination.
One operation. Feet in, arms in, one zip. Compared with trousers then jacket then checking the overlap, it is meaningfully faster, and multiplied across a room it is the difference described above.
The trade-off is the toilet, and it is real. A one-piece has to come off completely. For a child in nappies that changes nothing, since they are being changed by an adult anyway. For a child in the middle of toilet training it is a genuine complication, and it is the point at which some families switch.
Bib-and-brace dungarees with a separate jacket are the middle option and work well for the three-to-four age group: chest and back are covered so nothing is exposed at the waist, but the jacket comes off indoors without removing everything. Our guide to one-piece versus two-piece covers where that line falls in more detail.
Fastenings, cuffs and the details that decide it
Small design decisions have outsized effects when a garment is used this hard, this often, by this many hands.
A full-length zip beats a short one. The zip needs to open far enough that a child can step in rather than being posted through a small opening. Short zips are the commonest reason a suit takes twice as long as it should.
A zip guard at the chin. Something soft behind the top of the zip. One pinched chin and a child will resist that garment for the rest of the term, which costs far more time than the feature saves.
Generous ankle openings. Wide enough to pass over a shoe or a welly without a struggle. Narrow ankles mean shoes come off first, which doubles the operation.
Elastic rather than cords. Faster, and safer. Cords and drawstrings on children's clothing are restricted under BS EN 14682 because of snagging and strangulation risks, and any garment for this age should be using elastic, poppers or hook-and-loop instead.
Cuffs that close. Water travels up a sleeve the moment a child raises their arm, which at this age is constantly. An open cuff is the most common leak on any toddler garment.
A hood that stays up without being held. Toddlers will not hold a hood. If it needs holding, it is not being worn.
One more that sounds trivial and is not: a garment a child can identify as theirs. A distinctive colour means a two-year-old can point at their own suit, which is genuinely faster than a staff member reading eleven labels.
Nappies, toilet training and the practical reality
This is the part that decides which garment suits which term, and it changes fast at this age.
In nappies. A one-piece is straightforwardly the best option. The child is being changed by an adult on a mat regardless, so the fact that the suit comes off entirely is irrelevant. Coverage wins with no offsetting cost.
Toilet training. The awkward middle. Trips are frequent, urgent and often unsuccessful, and a one-piece adds a step to every single one. Many families move to a bib-and-brace or separates during this period specifically, then care less afterwards. It is a reasonable thing to change kit over.
Recently trained. Independence matters more, and a two-piece starts to make sense, though for outdoor sessions on wet ground coverage still argues the other way.
Worth telling the setting which stage you are at and asking what they find works. Staff have seen the whole cycle many times and will have a view.
Also worth accepting that at this age you may buy twice in a year for reasons that have nothing to do with the garment failing. That is normal, and it is an argument for buying sensibly rather than expensively, and for keeping outgrown kit in good enough condition to hand on.
Sizing a child who is growing fast
One-pieces have the shortest useful life of any rainwear, because they have to fit in two dimensions at once. Length runs out while the garment still fits around the body, and the crotch drops and shortens the child's stride.
Size over the clothes that will be underneath in winter, not over a summer t-shirt. One size of growing room is sensible. Two is not: sleeves that swallow the hands funnel water down the arm, and legs that puddle on the floor are a trip hazard for a child who is not yet steady on wet surfaces.
The signal that a size is finished is usually the ankle or the crotch rather than the chest. When the hem sits above a welly top, or the child's stride shortens, it is done regardless of how it fits elsewhere.
Buy by height rather than age where a chart allows it. Age labels vary between brands by several centimetres and toddlers vary more than the labels do.
Fleece-lined versions are worth considering for winter at this age specifically. Managing three separate layers on a two-year-old in a cloakroom is genuinely harder than managing one lined garment, and the layered system, better in principle, loses to the simpler one in practice.
Spares, labelling and shared space
Nurseries ask for spares because they need them, and the request is usually understated.
Send at least two complete changes of clothes, not one. At this age a single wet incident is routine and two is common, and a nursery with no spares left will put your child in whatever the communal box holds.
Label everything, in a way that survives. Ink fades, iron-on labels lift, and a name written on a care label is unreadable within a term. Write it somewhere it can be re-done, and check it occasionally.
Label wellies inside as well as out. Twelve pairs of small wellies lined up look identical, and they get swapped constantly.
Choose a colour your child recognises. This is the single most practical argument for bright colours at nursery age, and it has nothing to do with visibility to traffic: a child who can identify their own suit speeds up the whole room.
Ask what the setting provides. Many nurseries keep communal suits and wellies, some in every size, some only in the popular ones. If they do, ask whether they are shared between children and whether they are cleaned, since some parents would rather send their own for that reason alone.
Drying, hygiene and the shared peg problem
The thing that finishes nursery waterproofs is rarely wear. It is being wet for days at a time.
Most settings have nowhere to dry a soaked suit properly. Pegs are close together, wet garments hang against each other, and a suit that came in wet at eleven o'clock is still wet at home time. That is not a criticism of nurseries; it is a space constraint almost all of them have.
Which makes the home routine decisive. A suit that comes home wet and goes into a bag until the next morning grows mildew on the inside of the coating, and mildew inside a coating does not wash out. This is the commonest way this kit dies and it is entirely preventable: unpack it the same day, rinse the mud off while it is still wet, hang it somewhere airy away from a radiator.
Wipe clean rather than machine wash. Detergent and heat degrade coatings and lift seam tape at the edges, and once the tape lifts the garment stops performing regardless of what the label says. Check the care label, since a few fabrics differ.
Smooth, wipeable outer fabrics have a real advantage at nursery for exactly this reason. They shed surface water with a shake and a wipe, where a softer face fabric holds water in the weave and is still damp the following morning.
If a suit is genuinely soaked every day, two suits alternating is a more practical answer than one better one. It is also cheaper than replacing a mildewed garment in February.
Outdoor and forest nurseries
Settings that spend most of the day outdoors, or run woodland sessions for the under-fives, raise the requirement considerably.
Duration is the difference. A day nursery goes out for half an hour after lunch; an outdoor nursery may be outside for most of the session in weather a day nursery would keep children in for. That means full coverage is not optional, and it means warmth underneath matters as much as the shell.
Fleece-lined one-pieces come into their own here, as do proper wellies with room for a thick sock rather than the thin ones most toddlers own. Cold feet end an outdoor session faster than anything else, and wellies keep water out while insulating almost nothing.
Spares should be doubled again, and kept at the setting where possible rather than travelling daily.
Ask specifically about fire, tools and what the setting expects children to wear near either. Practice varies and the answers are worth having before you buy rather than after.
The general principle holds throughout: buy to the most demanding thing the child does in a normal week, and everything else is covered by default.
Frequently asked questions
What waterproofs does my child need for nursery?
A one-piece rainsuit and wellies, for most children under about three and a half. The one-piece removes the waist gap, which matters because toddlers sit and lie in everything, and it is one item for staff to manage rather than two. Add a fleece-lined version for winter if the setting is outdoors a lot.
Should I send a one-piece or separates to nursery?
A one-piece while your child is in nappies, since coverage wins and the toilet complication does not apply. During toilet training many families switch to a bib-and-brace or separates, because a one-piece adds a step to every trip. After training, either works and independence starts to matter more.
Do nurseries provide waterproofs?
Many keep communal suits and wellies, though not always in every size, and they are usually shared between children. Worth asking what they hold and whether it is cleaned. Plenty of parents send their own regardless, both for fit and because a suit that fits properly is quicker to get on.
How many spare clothes should I send?
At least two complete changes rather than one, and check the bag weekly. At this age one wet incident in a day is routine and two is common. Also swap the sizes when the seasons change, since a set packed in September will not fit by spring.
What size should I buy for a toddler?
Size over the clothes that will be underneath in winter, with one size of growing room and no more. Buy by height rather than age where you can, since age labels vary between brands. Watch the ankle and the crotch for the signal to size up, rather than the chest.
Why does the suit smell after a few weeks?
Because it has been stored damp. Most nurseries cannot dry a soaked suit properly between sessions, so it comes home wet and needs unpacking the same day. Damp coated fabric left in a bag grows mildew on the inside of the coating, which does not wash out.
Can I machine wash a nursery rainsuit?
Usually not, though check the label. Detergent and heat degrade the coating and lift the seam tape. Rinse the worst off while it is still wet, sponge with mild soapy water, and hang to dry away from direct heat.
If it is soaked daily, two suits alternating works better than one.
