Your toddler hides behind the sofa to poo, pulls at a wet nappy or wants to follow you into the bathroom. These are often the first hints that nappies are on their way out. Knowing when to stop using diapers is less about a date on the calendar and more about your child’s readiness. Here are the signs to watch for and how to make the switch calmly.
Quick answer: when to stop using diapers
- Most children are ready between 18 months and 3 years.
- Look for readiness signs, not age alone.
- Daytime dryness comes first; night-time dryness can take months or years longer.
- Choose a calm period for the switch.

Signs your toddler is ready
- dry nappies for 1 to 2 hours, or dry after naps
- telling you, or showing, when they are weeing or pooing
- disliking wet or dirty nappies
- interest in the toilet or in wearing pants
- able to walk to the potty, sit and pull trousers up and down with help
- following simple instructions
Moving from nappies to pants
- Talk about it first and read a book about using the potty.
- Choose a few days at home to start.
- Switch to pants in the daytime so your child feels when they are wet.
- Offer the potty regularly: after waking, after meals and before going out.
- Praise trying, not just success.
- Keep nappies or pull-ups for naps and nights for now.

Nights and naps
Staying dry at night depends on bladder development and hormones. Keep using a night nappy or pull-up until your child wakes dry most mornings. Bedwetting is normal until around 5 years.
Handling setbacks
- accidents are normal for weeks or months
- illness, a new sibling or starting childcare can cause regression
- if your child resists strongly, take a break and try again in a few weeks
- never punish accidents
When to talk to your doctor
- pain or burning when weeing, or weeing very often
- constipation, hard poos or holding in poo. See constipation relief
- your child was dry and starts wetting again without a clear reason
- no progress with daytime dryness by around 4 years
Frequently asked questions
Should I wait until summer?
Warmer months can make it easier with fewer layers, but readiness matters more than the season.
Are pull-ups helpful?
They can help for outings and nights, but some children learn faster in pants because they feel wet.
Is it too late to start at 3?
No. Many children train between 2.5 and 3.5 years.
