Potty Training for Preschool: What to Know
By First Cubby Editorial · Updated 2026-07-04
Many preschools require children to be potty trained before they start, so timing matters. Most children are ready to begin potty training between 2 and 3, and reliable daytime training often takes a few weeks to a few months. Policies vary — check each school.
Why it matters for preschool
A school’s potty policy can decide whether your child is eligible to start — it’s one of the fields worth confirming early (we flag it on every school). Some programs require full training; others have a younger, in-diaper class.
Signs of readiness
- Staying dry for longer stretches
- Showing interest in the toilet
- Telling you when they need to go
- Able to pull pants up and down
If the timing’s tight
Don’t rush training just to hit a start date — readiness matters more, and pressure can backfire. Talk to the school; many are flexible. See how to choose a preschool for what else to confirm.
Every child develops on their own timeline. This is general guidance — if you have concerns about your child’s development, talk to your pediatrician.

What age should a child be potty trained?
Most children are ready to begin between 2 and 3, and are reliably day-trained sometime between 3 and 4. Every child is different.

Often a few weeks to a few months from starting to reliable daytime training. Nighttime dryness can take longer.
What if my child isn’t potty trained by preschool?
