Potty Training Before School: What to Do If They're Not Ready by September

My School Agent | 26 August 2026

With about eight weeks to go before my son started school, he was still firmly attached to his nappies, and I was quietly convinced this would be the thing that went wrong. The pressure of a September deadline can turn potty training into a battle of nerves for the whole family. If you are in that boat, take a breath. Here is a calmer, more realistic way to think about it.

Try Not to Let the Deadline Panic You

A looming school start can make potty training feel urgent in a way that actually works against you. Children sense pressure, and stress tends to slow progress rather than speed it. The single most helpful mindset is calm persistence: children get there, and the vast majority are toilet trained around school age, just not always exactly on the timetable we would choose. Panic and pressure are the enemies of success here.

A Realistic Summer Plan

If you have some weeks before school, a steady approach tends to work better than an intense push:

  • Pick a stretch of time when you can be at home and consistent, without lots of disruption
  • Move into pants (not pull-ups) during the day once you commit, so they feel when they are wet
  • Offer the toilet or potty regularly and after drinks, meals and sleeps, keeping it low-key and positive
  • Praise successes calmly and warmly, and stay completely matter-of-fact about accidents
  • Dress them in easy-to-manage clothes they can pull down themselves, which also helps at school
  • Build in the independence school needs: wiping, flushing, hand-washing and pulling clothes up

Accidents Are Normal

Accidents are part of the process, not a sign of failure, and reacting to them calmly is important. Getting cross or showing frustration can make a child anxious, which makes accidents more likely. Clean up without fuss, reassure them, and carry on. Progress with potty training is rarely a straight line; there are good days and backward steps, and that is completely normal.

What If They Are Not Dry by September?

This is the worry that keeps parents up at night, so here is the reassurance: a child not being fully toilet trained by the time school starts is more common than you might think, and it is not a barrier to starting school. Schools are used to supporting young children, including those who have occasional accidents or need help. Key points:

  • Talk to the school before term starts if you have concerns, so they know and can plan support
  • Send in spare clothes, clearly named, and let staff know your child may need reminders or help
  • Schools should support a child who is not yet reliably dry, and cannot simply refuse a place because a child is not toilet trained, particularly where there is a delay or additional need
  • If your child has a medical reason or additional need affecting toileting, discuss it with the school, as they should make reasonable adjustments

When to Seek Advice

If your child is finding toileting particularly difficult, or there are signs of a physical issue such as constipation or discomfort, it is worth speaking to your health visitor or GP. There is also good, practical guidance on the NHS website, and charities such as ERIC, which specialises in children's continence, offer helpful support. You do not have to figure it all out alone.

Keeping the School Start Calm

The run-up to school brings a lot to organise alongside the potty-training worry, settling-in dates, uniform, forms and what to pack. My School Agent can pull all that out of the school's emails into a daily briefing and shared calendar, taking some of the mental load off you so you can focus on your child with patience rather than pressure. Stay calm, stay consistent, talk to the school, and trust that your child will get there. They almost always do, and usually sooner than the September panic suggests.
