Toilet training is learning to use a potty or toilet instead of nappies. According to the American Academy of Pediatrics, bladder and bowel control usually appears between 18 and 24 months, training often starts between 2 and 3 years, and most children are trained by age 4.

Key takeaways

  • Readiness matters more than age.
  • Pressure and punishment tend to slow progress.
  • Accidents are a normal part of learning.

What are the signs of readiness?

Signs include staying dry for at least 2 hours during the day or after naps, showing interest in the toilet, telling you when their nappy is wet or dirty, being able to pull pants up and down, and following simple instructions.

What you can do

  • Introduce a potty early and let your child sit on it at set times.
  • Use simple words for wee and poo and praise effort.
  • Stay calm about accidents.

When to talk to your doctor

Talk to your doctor if your child is still not dry during the day after age 4, has pain when weeing or pooing, is constipated, or starts wetting again after being dry.
