L.D.
Every child is differnt. I have 3 boys.
The oldest and youngest slept through the night by the time they were 2 1/2. The middle one was 6. He was a bed wetter. Some children are very heavy sleepers. I don't know if they still make this device but it sure did work when I needed it. It is called a POTTY PAGER. You place it in their underpants and it vibrates when they start to pee. It worked great. Try to google "Potty pager" and see if it is still around. There is nothing you can do about a child wetting the bed and you sure don't want to make the child feel bad about it. My boys are grown now. We survived. Some children wet the bed until they are 10. You may want to discuss this with yor pediatrician. Good luck.
