Toilet training: readiness, steps & setbacks
Every child learns to use the toilet in their own time. Calm, patient steps, lots of praise and no shame make it easier for everyone.
By the numbers
There’s a wide range of normal.
Ages
After training
Is your child ready?
Signs to look for, and why you don’t have to wait for all of them.
There’s no perfect age. The CDC notes that most children aren’t able to toilet train until 2 to 3 years old. Your child’s doctor or childcare teachers can help you decide when to start.
Signs your child may be ready (AAP)
- Asks to use the toilet or to wear “big-kid” underwear
- Can follow simple instructions
- Can walk to the bathroom and help undress
- Doesn’t like wet nappies or diapers
- Is dry for at least 2 hours at a time during the day, or dry after naps
- Shows by their face, body or words that a pee or poo is coming

The AAP describes readiness signs to look for. The NHS says you don’t have to wait for your child to show signs or ask before you start preparing. Both agree on a calm, child-friendly approach.
A middle path many families use: start the gentle getting-ready steps early, and move to pants when your child shows some interest.

It may take longer for children to notice the need to pee than the need to poo. That’s normal, not a sign that training is failing.

Starting nursery or childcare, moving house or a new baby can all affect progress. The NHS suggests choosing a calm time and keeping routines as steady as you can.

Toilet training often comes up at the 18-month, 2-year, 2½-year and 3-year well-child visits. It’s a great time to ask questions.
Getting ready before the nappies come off
Books, practice, the right seat and a happy tummy.
A little preparation makes the big switch feel familiar. These steps can start weeks before you stop using nappies or diapers.

Reading books about potties and using dolls or toys to show what happens helps children know what to expect.
Read more
The NHS suggests regular nappy-free time of around 30 minutes after your child has done a wee or poo, so they start to notice what their body feels like.
Read more
Some families use a potty; others use a child seat on the toilet with a step. With a step, your child’s knees should be higher than their hips, which makes pooing easier.
Read more
If poos are hard, dry or look like small pebbles, or your child strains, they may be constipated. The NHS says to get help with this from a doctor or health visitor before stopping nappies.

Pick simple words for pee, poo and body parts and use them calmly and matter-of-factly. Keeping the same steps every time, including wiping and handwashing, helps your child learn the routine.
A simple step-by-step plan
Pants on, regular tries, same routine every time.
5 steps (adapted from the NHS)
- Prepare your child: pick a calm time and tell them about the change ahead of time, in simple words.
- Switch to pants in the daytime: stop daytime nappies and pull-ups, but keep them for naps and night-time for now.
- Build a routine: offer the potty when they wake, after meals, before going out, before naps, and before bed. Watch for signs like fidgeting, going quiet or making faces.
- Praise the effort: celebrate trying, whether or not anything happens.
- Build independence: help your child learn to wipe, pull pants up and down, flush and wash their hands.

The AAP suggests keeping the potty in the same place, using the same sequence each time, and having every caregiver use the same approach.
Read more
Think about whether your child learns best by talking or by doing, and whether they like adult-set routines or prefer to be in charge. A child who wants control may do better choosing when to try.
Read more
If your child finds it hard to sit for long, reading or singing together can help. Keep tries short and relaxed.
Read more
Clothes your child can pull down quickly by themselves, like loose pants with elastic waists, make success easier. By 3, many children can put on some clothes, like loose pants, by themselves.
Praise without pressure
Celebrate tries, keep it light, skip the nagging.
Children learn best when they’re praised for progress rather than punished for mistakes. Most children learn to use the toilet eventually, so try not to take hesitation, fears or resistance too seriously.
Read more
Praise effort whether or not your child manages a wee or poo. Celebrate each success with a hug and praise.
Read more
A small tangible reward, like a sticker, can add to praise for some children. Keep rewards small and focused on effort.
Read more
The AAP notes that being overly controlling, like constantly asking if your child needs to go, can lead them to resist until an accident happens. Offer at natural times instead.
Read more
The AAP suggests clear, reasonable expectations based on your child’s abilities, stated often, and expecting at least an effort every time.
Read more
Not so helpful
- “Big kids don’t do that.”
- “Your cousin was trained ages ago.”
- “You did it on purpose.”
- “Yuck, that’s disgusting.”
Try instead
- “Your body is learning. We’ll keep practising.”
- “Wee goes in the potty. Let’s go try.”
- “That’s OK. Accidents happen when we’re learning.”
Accidents: calm, quick and no shame
Accidents are part of learning, for months.
Accidents are a normal part of learning and happen to most children. Daytime accidents can carry on for months after training seems complete, sometimes at 3 or 4, and usually start to ease about 6 months after training.
Read more
The NHS suggests staying calm, cleaning up together and moving on. The AAP says there is no cause to criticise or punish a child for accidents.
Read more
The AAP suggests a predictable, non-punishing response, like having your child help clean up, and telling them you’re confident they’ll do better next time.
Read more
Around age 3, children start to feel shame and may hide wet pants or try to clean up themselves. It actually shows they know what’s expected. Respond calmly and make a plan together.
Read more
Offer the toilet before leaving home and when passing a toilet. A small bag with spare pants, clothes and wipes helps you stay calm if an accident happens.
Read more
Children learn best when they’re praised for progress, not punished for mistakes. If you feel your temper rising, put your child somewhere safe and step away for a few minutes.
Poop worries & holding on
Fear, constipation and children who only poo in a nappy.
Some children are scared to poo on the toilet, often because pooing was hard or painful before. Holding it in can lead to constipation, which makes the next poo hurt more, and the cycle continues.
Read more
If poos are hard, pebble-like or painful, or your child strains, talk to your child’s doctor or health visitor. Getting constipation treated makes toilet training much easier.
Read more
Sitting with knees higher than hips, with a step under the feet, makes it easier to poo.
Read more
A children’s hospital suggests “diaper fading.” Your child wears underwear while awake and a nappy only for poos. Little by little, every 2 to 3 days, the poo spot moves closer to the bathroom, then they sit on the toilet wearing the nappy.
After that, a small slit is cut in the nappy and made a bit wider every 2 to 3 days, until it’s no longer needed. Every poo in the bathroom gets praise or a small reward.
Read more
Toddlers have vivid imaginations, and some develop fears about the toilet. Listen, name the fear, and look for small solutions together, like flushing after they leave the room or using a potty first.
Read more
Call your child’s doctor if your child
- Has blood in their poo
- Has severe tummy pain
- Hasn’t pooed in more than 3 days
- Keeps vomiting
Naps & night-time
Dry nights usually come later, on their own timetable.
Staying dry at night is a different skill from daytime training. Most children become dry at night after they’re dry in the day, and it happens naturally over time.
Read more
The NHS suggests moving to pants for naps once your child is regularly staying dry when they nap.
Read more
Night-time wetting can carry on well after daytime training. About 1 in 6 children still wet the bed at age 5, and bedwetting usually isn’t a concern until 5 or 6.
Read more
Bedwetting often runs in families. Children don’t do it on purpose, and it isn’t caused by laziness or bad behaviour.
Setbacks & going backwards
Regression is common, and usually short.
Skills can seem to disappear for a while, even after weeks of success. Regression usually doesn’t last long, often a few days or weeks, and it can be a healthy way for a child to cope when life feels overwhelming.
Read more
Things that can set training back
- A change in childcare
- A major illness
- A move
- A new baby or a pregnancy
- A recent death in the family
- Conflict between parents, or a separation
- Constipation or painful poos
- A urinary tract infection
Read more
Regression can sometimes signal an infection or another problem that needs treatment. The AAP suggests having your child checked to be sure the cause isn’t physical.
Read more
Talk with your child about what has changed and listen to their answers. One-on-one time, familiar objects near the potty and inviting your child’s ideas can all help.
Read more
The AAP suggests avoiding big steps back, like returning to nappies full-time, and offering smaller compromises instead, like training pants or a potty in their room.
Read more
If regression lasts a month or more, it’s worth asking whether your child was fully ready. A short break can help, though moving forward, however slowly, is usually best.
Different needs, different homes, many helpers
Some children need more time; every caregiver needs the same plan.
Children with disabilities or additional needs can still learn toileting skills. They may need more time or extra support, and that’s OK.
Read more
For children who find the bathroom overwhelming, the NHS suggests ideas like ear defenders, or a mild scent the child likes. Sensory differences has more on this.
Read more
If progress is slow, keep offering opportunities to practise and celebrate small wins. Visual routines can help some children, and Parenting an autistic child has more ideas.
Read more
The AAP stresses that every caregiver should use the same approach. Share your words, routine and how you handle accidents with everyone who cares for your child.
Read more
If your child moves between homes, try to agree on the same words, the same routine and a calm response to accidents. Big family changes, like a separation, can set training back for a while.
Read more
If school is coming up and your child still needs help with the toilet, the NHS suggests contacting your health visitor or doctor so you can make a plan together.
When and where to get help
Signs to check with your child’s doctor, and support for you.
Talk with your child’s doctor if…
- Your child often has hard, pebble-like or painful poos, or strains
- Your child is 3 and having frequent accidents that aren’t getting better
- Training was going well and then went backwards with no clear reason
- There is blood in their poo, severe tummy pain, or no poo for more than 3 days
- Your child is worried, ashamed or avoiding the toilet in a way that worries you
You can talk to your child’s doctor or health visitor at any time, even if nothing seems wrong. If a checkup finds nothing physical, that can be a relief; if it finds something, early help can make things easier.
