Does a 8 year old boy have control over wetting the bed with no kidney problems ?

Bed wetting?: Sometimes. This is a common problem, especially in boys. It is a maturity problem. Sometimes the child is in such deep sleep he does not feel the urge enough to wake up. You can try getting him up every night after a few hours of sleep and walk him to the bathroom to empty his bladder. If done every night, it may help his internal clock. Talk to your doctor about other remedies that may help.

Rarely: No kid wants to wake up in a bed filled with pee.Most are quite embarrassed by the process but may be mute or deny it happens.Usually one or both parents had something similar in childhood. There are programs that help. An evaluation by your pedi and the assistance of a bedwetting program will help most.
