Nighttime dryness is not always achieved at the same time that daytime dryness is achieved. In general, girls accomplish daytime toilet training around 2-2.5 years and boys at 2.5-3 years. For a variety of reasons, nighttime dryness sometimes takes longer—this is normal. Most children will achieve nighttime dryness by age 5. However, 10% of 7 year olds still regularly wet the bed as do 3% of teens.

Nocturnal enuresis (bedwetting) can be frustrating and embarrassing and can keep a child from participating in desired activities like sleep-over’s or overnight camping. If your child is at least 5 years old, wets the bed at least twice per week for at least three consecutive months and you would like to discuss it, please call and make an appointment. Sometimes there are medical reasons for bedwetting that can be addressed and which solve the problem. Often there are ways to speed up the time to consistently dry nights.
