By the numbers

There’s a wide range of normal.

Ages

18–24 monthsis when children usually start to show signs of bladder and bowel control.
2–3 yearsis the average age toilet training begins in the United States.
18 mo–2½ yrsis the age range in which almost all children can be potty trained, according to the NHS.
By 4most U.S. children are bowel and bladder trained, and most stay dry during the day.

After training

~6 monthsafter training is when daytime accidents should start to become less frequent. Night-time wetting can last longer.
1 in 6children still wet the bed at age 5.
1 in 10children have trouble with daytime wetting at age 5.
Every other dayat least is how often a child should be doing soft poos. Hard poos or straining can mean constipation.

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
⚖️ Two views on readinessWait for signs, or start gently from about 18 months.
Read more

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.

💧 Pee can take longer than pooNoticing a full bladder is harder.
Read more

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.

🗓️ Pick a calm timeAvoid starting during big changes.
Read more

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.

🩺 Ask at checkupsYour child’s doctor can help you decide.
Read more

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.

📖 Make it familiarBooks, dolls and watching others.
Read more

Reading books about potties and using dolls or toys to show what happens helps children know what to expect.

🌞 Nappy-free timeAbout 30 minutes after a wee or poo.
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.

🚽 Potty or toilet seat?Either works. Feet need support.
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.

💩 Check for constipation firstSort out hard poos before you start.
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.

🗣️ Simple wordsChoose your family’s words and use them every time.
Read more

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)

  1. Prepare your child: pick a calm time and tell them about the change ahead of time, in simple words.
  2. Switch to pants in the daytime: stop daytime nappies and pull-ups, but keep them for naps and night-time for now.
  3. 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.
  4. Praise the effort: celebrate trying, whether or not anything happens.
  5. Build independence: help your child learn to wipe, pull pants up and down, flush and wash their hands.
📍 Same place, same stepsPredictable routines help it stick.
Read more

The AAP suggests keeping the potty in the same place, using the same sequence each time, and having every caregiver use the same approach.

🧩 Fit the plan to your childA talker, a doer, or a “me do it” kid?
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.

🎵 Make sitting funA song or a book while they wait.
Read more

If your child finds it hard to sit for long, reading or singing together can help. Keep tries short and relaxed.

👖 Easy clothesElastic waists win.
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.

👏 Praise the trySitting counts, even if nothing happens.
Read more

Praise effort whether or not your child manages a wee or poo. Celebrate each success with a hug and praise.

Try saying: “You sat on the potty and listened to your body. That’s great trying!”
⭐ Small rewards, if they helpStickers, a dance, a call to Grandma.
Read more

A small tangible reward, like a sticker, can add to praise for some children. Keep rewards small and focused on effort.

🔕 Don’t keep askingConstant reminders can backfire.
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.

🎯 Clear, kind expectationsExpect a try, not perfection.
Read more

The AAP suggests clear, reasonable expectations based on your child’s abilities, stated often, and expecting at least an effort every time.

🙊 What not to sayLeave out shame and comparisons.
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.

😌 Stay calmTry not to get angry or upset.
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.

Try saying: “Oops, your pants got wet. Let’s get clean ones. Next time we’ll try the potty.”
🧽 Help clean up, not as punishmentA small, predictable job.
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.

🙈 Hiding accidentsAround 3, shame can creep in.
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.

🎒 Be ready when you go outA spare-clothes bag takes the stress out.
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.

🛑 Never physical punishmentIt makes things worse, not better.
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.

Discipline without yelling or hitting: what actually works has more on calm responses.

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.

🩺 Treat constipation firstHard or painful poos need a doctor’s help.
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.

Bedwetting & toilet troubles explains constipation, soiling and how they link to wetting.
🦶 Feet up, relaxed bodyA step under their feet helps.
Read more

Sitting with knees higher than hips, with a step under the feet, makes it easier to poo.

🔄 Only poos in a nappy?Move step by step toward the toilet.
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.

🫂 Fears are realFlushing, falling in, or the feeling of letting go.
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.

📞 When to call the doctorPain, blood, or no poo for 3 days.
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.

😴 Naps firstTry pants at nap time once naps are usually dry.
Read more

The NHS suggests moving to pants for naps once your child is regularly staying dry when they nap.

⏳ Nights take longerKeep night nappies or pull-ups as long as needed.
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.

💛 It isn’t lazinessChildren can’t control night wetting.
Read more

Bedwetting often runs in families. Children don’t do it on purpose, and it isn’t caused by laziness or bad behaviour.

Bedwetting & toilet troubles covers night wetting in older children in depth.

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.

🌪️ Common triggersBig changes, big feelings, or a body problem.
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
🩺 Rule out a body causeCheck with the doctor first.
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.

🫂 Connect and listenExtra one-on-one time helps.
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.

🤝 Small compromises, not a full resetKeep moving forward, gently.
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.

⏸️ When a break makes senseIf it lasts a month or more.
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.

🎧 Sensory-friendly bathroomsNoise, smells and feelings can be a lot.
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.

🐢 Slow progress is still progressKeep offering chances to practise.
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.

👵 Childcare, grandparents and sittersSame words, same steps everywhere.
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.

🏡 Two homesAgree on the basics, even if houses differ.
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.

Parenting as a team: getting on the same page has tips for agreeing a shared plan.
🏫 Starting school soon?Ask for a plan early.
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.
