Potty Training, Synced with Daycare
Readiness over the calendar — and the same words and routine at home and at daycare, so your child only has to learn this once.
A calm, judgment-free guide for parents in the Netherlands. There is no single right age to start, the evidence behind every 'method' is thinner than the internet suggests, and Dutch children tend to start later than in the US or UK — which is completely fine. What matters most is that home and the daycare group (kinderopvang) pull in the same direction.

Readiness, not the calendar
Staying dry is something a child grows into, not something you can drill in. The physical awareness of a full bladder or bowel usually appears somewhere between one and two years old, and the ability to hold on and let go on purpose keeps developing through the second and third year. You can support that maturing — you cannot force it.
That is why there is no single 'correct' age to start, and why Dutch children often begin later than children in the US or UK. Dutch guidance treats daytime dry at roughly 2.5 to 3 years, and dry at night around 3 to 4 years, as the normal range — not a deadline you are behind on.
This guide keeps one thing at its centre: your child spends the day in two places, home and the daycare group. When both use the same words and the same rhythm, your child learns this once instead of twice.
Signs your child may be ready
Dutch, US and UK guidance all point at the same cluster of signs. You are not waiting for every box to be ticked — a handful appearing together, fairly consistently, is the signal that it may be worth starting gently. None of them is a stopwatch.
Body awareness
The physical foundationYour child notices a full bladder or a coming poop — pausing, going quiet, hiding, or telling you the nappy is wet or dirty. This awareness is what training builds on; without it, drilling just creates stress.
Staying dry for stretches
Roughly 1.5–2 hoursA nappy that is regularly dry after a nap or for a couple of hours suggests the bladder can now hold and store — a physiological milestone, not a behaviour you taught.
Growing independence
Wanting to do it themselvesPulling trousers up and down, wanting to copy others on the toilet, saying 'no' and 'me do it'. This drive to be independent is fuel for learning — potty training rides on it.
Understanding and interest
Following simple instructionsFollowing a short instruction ('go sit on the potty'), naming pee and poop, and showing curiosity about the toilet all mean your child can follow the thread of what you are asking.
A gentle rule of thumb
- Several signs together matter more than any single one
- Girls often show signs a little earlier than boys — a population tendency, never a rule for your child
- Skip the start during big changes (a move, a new sibling, a group switch) — those are also the classic regression triggers
- Not ready yet is information, not failure — you can revisit in a few weeks
How old is 'normal'? The honest picture
Parents comparing notes across countries often panic for no reason. The ranges below overlap far more than they differ — and where credible sources genuinely disagree, we say so instead of pretending there is one answer.
The Netherlands (NJi, JGZ)
- Gradual and readiness-based, deliberately unhurried in tone
- Daytime dry around 2.5–3 years seen as normal
- Night dryness around 3–4 years, and often later, seen as normal
- Coordinating with the daycare group is built into the core advice
- Dutch children have trended later over recent decades — later, not worse
US (AAP/AAFP) & mainstream UK (NHS)
- Also readiness-based; wait for the signs, don't push before age 2
- US: anticipatory advice at 18–24 months, most dry by 30–36 months
- UK NHS: 2–2.5 years a 'good time to think about starting'
- By age 3, most children are dry most days; by 4, reliably dry by day
- Broadly overlaps the Dutch range — the gap is smaller than it feels
The real disagreement: ERIC (UK)
- ERIC — the UK's dedicated children's bladder-and-bowel charity — argues the opposite on one point
- It says the idea of waiting for 'readiness signs' is not backed by strong research evidence
- It recommends introducing potty-sitting earlier (from around 6–9 months) and stopping nappies between 18–30 months
- This is a genuine clinical-philosophy split with the AAP/AAFP/NJi readiness approach — not a wording quibble
- We flag it rather than pick a side: the underlying research is thin either way, so reasonable experts land differently
Our reading: pick the approach that fits your child and your family, apply it calmly and consistently, and coordinate it with daycare. The evidence does not crown a winner, so your confidence and consistency matter more than which camp you join.
The 'methods', graded honestly
First, the caveat the internet skips: the research on potty-training methods is genuinely thin. Most studies are small, decades old, or tied to whoever is promoting a method, and a well-known systematic review found no strong evidence that any one method beats another. So read the grades below as 'weak evidence, expert opinion' across the board. The methods differ in pace and how much parent effort they ask for — not in a proven better outcome.
Gradual / child-oriented
Evidence: low–moderate · the Dutch defaultWait for child-led readiness signals, introduce the potty casually, and follow your child's pace over weeks to months with low pressure. This is the approach underlying most Dutch (NJi, GGD) and mainstream UK/US guidance in practice.
- Lowest stress for child and parent
- Fits naturally around a daycare week
- An older observational study saw most children trained by around 3, nearly all by 4 — but it was not a head-to-head trial
Intensive '3-day' / Azrin–Foxx style
Evidence: low–moderate, old studiesA concentrated, parent-led push over one to a few days: lots of drinks, frequent potty prompts, immediate praise, often practising with a doll. The original 1970s clinical protocol required the child to pass a readiness checklist first, and its results seem to hinge on that screening — not on squeezing it into a single day.
- Can work fast for a genuinely ready child
- In a later replication, some children could not complete the intensive protocol due to distress, or parents stopped — so it is not for everyone
- The commercial '3-day method' branding has essentially no evidence base of its own; it borrows the old clinical research
Child-led (following cues, no fixed start)
Evidence: very low for deliberate delayTwo different things share this name. Actively offering the potty and following your child's cues is really the gradual method above. 'Just wait until the child asks', passively, is less supported — and starting very late (after about 3.5 years) is actually linked to more stool-withholding, not less.
- Respecting real cues is sound
- Deliberately delaying as a strategy is not supported by the evidence
- If you are waiting, keep gently offering the potty — don't switch to doing nothing
The one-line takeaway
- No method is proven superior for a typically-developing child
- Elimination communication (very early infant training) is a separate practice, outside the scope of this guide — ask your consultatiebureau if you're curious
- Choose for your family, then be calm and consistent — that is the part that actually helps
Syncing home and daycare
This is the part that makes the difference. Your child learns this in two places at once, so the goal is one plan, spoken the same way in both. In the Netherlands, where most toddlers are in kinderopvang, coordinating with the group is part of the standard advice — not an extra.
Talk to the mentor first
Before you change anything at home
Start with a short chat with your child's fixed caregiver (mentor / pedagogisch medewerker). Ask what they are already seeing in the group, whether the timing feels right to them too, and how the group usually does it. Starting on the same page beats surprising each other later.
Agree the same words
One word for pee, one for poop
Pick one phrase for 'I need to pee' and one for 'I need to poop', and use exactly those at home and in the group. A child who says 'plas' at home should hear 'plas' at daycare too — otherwise they are relearning the vocabulary in each setting.
Line up the routine and cues
After meals, before naps
Agree the natural potty moments — after meals, before the nap, before going outside — so home and daycare reinforce the same rhythm instead of contradicting it. Predictable moments are easier for a toddler than being asked at random.
Clothes that work everywhere
Easy up, easy down
Send your child in easy pull-down leggings or joggers, and skip tricky buttons, tight jeans and dungarees on training days — at home and at daycare. When a child can manage their own trousers, they can catch the moment in time.
Name the day nappies stop
Be specific, not vague
Tell the group the exact day or week the daytime nappy comes off, not just 'we're working on it'. A clear switch point lets staff apply the same consistency you do — and pack a generous stack of spare clothes in the bag for both places.
Expect a slower pace in the group
And accidents in both places
A child deep in play with friends will 'forget' more often at daycare than at home. That is normal and expected — not a sign your home approach isn't working. Accidents happen in both places while learning; treat them the same calm way everywhere.
- One vocabulary and one routine, so your child learns it once
- Staff and parents catch regressions and worries early, together
- Fewer mixed signals means a calmer, faster settle overall
When it goes backwards (terugval)
A child who was doing well suddenly having accidents again is one of the most normal things in this whole process — 'heel normaal', as Dutch sources put it. It is almost always temporary and tied to something changing in their world, not a failed method. The response is the same in both places: stay calm, never shame.
Common triggers
- A new baby brother or sister
- A house move or a new bedroom
- Moving up a daycare group, or changing location
- Illness — especially anything that makes weeing or pooping hurt
- A disrupted routine: holidays, family stress, a new caregiver
- Growth spurts — Dutch sources name these as a normal wobble window
What helps
- Treat it as temporary and keep your reaction low-key — no punishing, no shaming
- Tell the daycare mentor so both places respond the same gentle way
- If it persists, it is fine to pause for a few weeks rather than push through
- Rule out a physical cause first — constipation or a bladder infection (UTI) — before assuming it's 'just behaviour'
- If a painful wee, a fever, or blood appears, or it drags on, ask your huisarts or consultatiebureau
Night dryness is a different journey
Dry days and dry nights are not the same skill, and conflating them scares parents for no reason. Being dry at night depends on a separate biological maturation — a night-time hormone that concentrates urine, bladder capacity, and waking to a full bladder — and it typically lags daytime dryness by about a year, often more. You cannot train it; you wait for the body to be ready.
Bedwetting stays normal for years
Long after daytime drynessIt is common for children to still wet the bed (bedplassen / enuresis nocturna) well into the preschool and early-school years — a meaningful share of four- and five-year-olds still do, and it steadily becomes rarer with age. On its own, in a child under about six or seven, it is not a medical problem and should never be framed to the child as one.
It often runs in the family
Ask the grandparentsIf one or both parents were late to be dry at night as children, their child is more likely to be too. That is heredity at work, not anything you did — and it usually resolves on its own with time.
Gentle, low-pressure support
Not trainingA waterproof mattress protector, a last toilet trip before bed, and easy access to the toilet or potty at night all help everyone sleep. Keep it matter-of-fact — no rewards or charts for something outside the child's control.
When to bring it up with a professional
- Signpost, not treatment: for reassurance or a plan, start at the consultatiebureau / JGZ or your huisarts
- Dutch guidance considers it worth a professional look when wetting is persistent and frequent in a child old enough that it's no longer developmentally expected — a frequency-and-age judgement, not a hard cutoff
- Night-wetting that returns after 6+ months of being reliably dry deserves a huisarts chat at any age — it can signal a physical or emotional trigger
- Trust the professionals over a percentage on the internet — the exact age figures online vary and are not our call to state as fact
The hidden saboteur: constipation & withholding
This is the one many parents miss. Constipation and stool-withholding (het ophouden van ontlasting) are a common, under-recognised reason toilet training stalls, or a previously-trained child suddenly starts having daytime or poo accidents. It is well worth ruling out before you assume a setback is behavioural or motivational — and it is firmly a doctor's territory, not a DIY fix.
How the cycle sneaks in
- It often starts with one painful or frightening poo
- The child learns that pooping can hurt, and starts holding it in
- Held stool grows harder and larger, so the next one hurts more
- That confirms the fear — and the withholding deepens
- The result can look exactly like a behavioural regression, but the root is physical
What to do (ask, don't self-treat)
- If you see withholding, hard or painful poos, or a sudden run of accidents, talk to your huisarts or consultatiebureau — this guide gives no dosing, laxative or diet-as-treatment advice
- thuisarts.nl describes a specific 'poeptraining' track for children who are withholding — scheduled short toilet sits after meals plus a stool diary — but it is run with a doctor, as a distinct path from ordinary potty training
- General good habits (enough fluids, fibre, movement) support healthy poos, but that is everyday health advice, not a treatment for a constipated child
- Tell the daycare mentor too, so the group watches for withholding signs and keeps toilet time calm and unhurried
Frequently asked questions
My friend's child was dry at 2 and mine isn't near it. Is something wrong?
Almost certainly not. The normal Dutch range for daytime dry is roughly 2.5 to 3 years, and plenty of children fall outside it in both directions. Readiness varies enormously between individual children, and girls often show signs a little earlier than boys. Comparison is the thief of calm here.
Should we do a '3-day' intensive method?
You can, if your child is genuinely showing readiness signs — that screening seems to matter more than the three days themselves. But be honest that the commercial versions have little evidence of their own, and some children find the intensity distressing. A calmer, gradual approach reaches the same place with less pressure. There's no proven winner.
How do we make sure home and daycare do the same thing?
Start with a short conversation with your child's mentor before you change anything. Agree the exact words for pee and poop, the potty moments (after meals, before naps), the easy pull-down clothes, and the specific day nappies come off. Pack plenty of spares for both places. That shared plan is the whole point of this guide.
My child is dry at home but has lots of accidents at daycare. Why?
This is completely normal. A child absorbed in play with friends 'forgets' more easily in the group than in the quiet of home. It is not a sign your approach is failing — it's the pace of learning in a busier setting. Keeping the words and routine identical in both places is what closes the gap over time.
We started and it's clearly not working. Can we stop?
Yes. If it has become a daily battle, pausing for a few weeks and trying again later is a legitimate, common choice — not a defeat. First, gently check for a physical cause like constipation. Then let your child's mentor know you're pausing, so daycare pauses with you rather than pushing on.
When should night dryness happen?
Later than days, and on its own schedule — roughly a year behind daytime dryness on average, and often longer. Bedwetting stays normal for years, well into the early-school years for a meaningful share of children, and it frequently runs in families. It cannot be trained; you wait for the body. If it worries you, or wetting returns after months of dry nights, ask your consultatiebureau or huisarts.
Which is better for daycare, a potty or a toilet trainer seat?
Both work — it's about what your child is comfortable and confident with, and what the group already uses. Many children start on a low potje for the sense of security and stability, then move to a toilet with a seat reducer (toiletverkleiner) and a step stool. Ask the mentor what the group typically offers so home can match it.

About this guide
This guide is for education and reassurance, not medical advice. It draws on Dutch (NJi, JGZ), US (AAP/AAFP), UK (NHS, ERIC) and other sources, and is honest that the research behind potty-training methods is limited — where credible sources disagree, we show the disagreement rather than pick a side, and we keep secondary statistics qualitative. It does not describe any specific Teddy Kids protocol. For anything about your individual child — persistent accidents, constipation, painful weeing, bedwetting worries, or when to start — speak with your consultatiebureau (JGZ), huisarts, or your child's daycare mentor.
