Bedwetting is when a child doesn't wake from sleep when they need to pee. Doctors may use its medical name, nocturnal enuresis.
If a child knows when to use the toilet during the day, but wets at night, it means their brain hasn't linked the need to pee with the need to wake up.
Bedwetting is uncommon in older children. More than half of children have learned to stay dry at night by age 3 years 6 months. If a child still wets the bed at age 5, they and their family may start having social problems and hurtful feelings.
Of 8-year-old children, only 1 in 20 are still bedwetting, and just 1 in 50 at 15 years old.
Wetting the bed at age 5 or older can be a problem for a child and their family, partly because children the same age have usually stopped bedwetting.
It helps to start treatment with a bedwetting alarm by age 6 for girls and 7 for boys. Bedwetting gets harder to treat as children get older.
Kids who wet the bed may need help to learn to wake when they need to pee.
Whether it's normal or abnormal at their age, to stop wetting the bed is a great achievement for a toddler, child or adolescent.
