The age that a child will stop bed wetting can vary from child to child.
Some children stop wetting the bed as early as 5 to 8 years old while others may not stop wetting the bed until they're 15 to 16 years old.
And for some people bed wetting can be lifelong.
I used to wet the bed as a kid and continued to wet the bed until 15 years of age which I finally stopped wetting the bed.
It's normal for children and some teens to wet the bed and most people do grow out of it.
