Nighttime potty training is often misunderstood — and it usually happens later than daytime training.
Staying dry at night depends largely on physical development, not willpower or practice. That's why nighttime accidents are common and completely normal, even after a child uses the toilet independently during the day.
This section explains when to start nighttime potty training, how to set realistic expectations, and how to support your child without pressure, shame, or power struggles.
Nighttime dryness requires the brain to produce a hormone (ADH) that reduces urine production during sleep. This develops on its own timeline — you can't train it.
Some children stay dry at night by age 3, others not until 6 or 7. Up to 15% of 5-year-olds still wet the bed — this is within normal range.
Restricting drinks before bed has minimal effect. The bladder needs practice holding urine, and dehydration can actually worsen the problem.
Children can't control nighttime wetting. Punishment or embarrassment creates anxiety, which can actually increase accidents and delay progress.
When your child wakes up dry most mornings for 2+ weeks, their body may be ready. Until then, use pull-ups without shame.
Build a consistent routine: brush teeth, read story, final bathroom trip. This habit helps empty the bladder before sleep.
Use waterproof mattress covers. This removes stress about accidents and makes cleanup quick and easy.
Don't make a big deal about dry or wet nights. Matter-of-fact responses help your child feel secure rather than pressured.
