If your potty trained child has suddenly started having accidents again, you're not alone. Potty training regression is more common than many parents expect, and it doesn't usually mean your child has forgotten everything they've learned.

A child can stay dry for weeks or even months before accidents suddenly return. While it can be worrying, there's often a simple explanation. Understanding what's causing the accidents is the first step towards helping your child get back on track.

 

Common Reasons for Potty Training Regression

There are several reasons why a potty trained child might start having accidents again.

They're too busy to notice

Young children often become so absorbed in playing that they ignore the early signs they need the toilet. By the time they realise, it's too late.

Some children know they need the toilet but put it off because they don't want to interrupt what they're doing. A quick "I'll go in a minute" can easily turn into an accident.

Their routine has changed

Big milestones such as starting nursery, moving house, welcoming a new sibling or getting ready to start school can all affect your child's confidence and routine. During periods of change, temporary accidents are common.

Constipation

Constipation is one of the most common causes of potty training accidents. A full bowel can press against the bladder, making it harder to hold or fully empty wee. Because the symptoms aren't always obvious, many parents don't realise constipation is the cause.

 

What you can do to help

If your child has started having accidents again, try to stay calm. Children are often embarrassed by accidents, and showing frustration can make them more worried about using the toilet.

Instead, try to:

• Rule out constipation first. Look for signs such as infrequent poo, hard stools or straining. If you're concerned, speak to your GP or health visitor.

• Encourage regular toilet trips every couple of hours rather than waiting for your child to ask.

• Watch for signs they need the toilet, such as fidgeting, going quiet or holding themselves.

• Praise successes calmly, focusing on their effort rather than making a big fuss.

Most importantly, remember that setbacks are a normal part of learning. With patience and consistency, most children regain their confidence.

 

Why do accidents often happen when children start school?

Starting school is a big milestone, and it's common for children who have been dry at home to have a few accidents during the transition.

School toilets are very different from the ones they're used to. Your child needs to recognise when they need the toilet, stop what they're doing, find the toilets, manage their clothing independently and, in some schools, ask an adult for permission to go. For some children, that's a lot to remember while they're still settling into a new routine.

There are also new challenges, such as unfamiliar toilets, queues, less privacy, and not wanting to miss out on playtime. It's easy to see why accidents can happen, even after months of successful potty training.

FAQs

Why has my potty trained child started having accidents again?

If your potty trained child has started having accidents again, it's often due to a change in routine, distraction, worries about using the toilet or constipation. Potty training regression is common, especially during big milestones such as starting nursery or school, and it rarely means your child has forgotten their toilet training.

 

Can constipation cause wetting accidents?

Yes. Constipation is one of the most common causes of wetting accidents in potty trained children. A full bowel can press against the bladder, making it harder for your child to hold or fully empty their wee. If you think constipation could be the cause, speak to your GP.

 

Should I go back to nappies during a potty training regression?

In most cases, it's best to continue encouraging your child to use the potty or toilet rather than returning to nappies. Going back to nappies can make it harder for your child to reconnect with the feeling of needing the toilet. Instead, stay calm, pack spare clothes and offer regular opportunities to use the toilet without pressure.

 

How do I prepare my child for school toilets specifically?

Help your child practise the skills they'll use every day at school, such as recognising when they need the toilet, managing their clothing independently, wiping, flushing and washing their hands. It can also help to talk about what school toilets might be like and encourage your child to ask an adult if they need help. Building these skills before they start school can help them feel more confident in their new environment.
