What do you suggest if my child is 8 and wetting the bed?

Alarm clock. After the age of 8 it may be worth using an enuresis alarm clock. This alarm clock goes off when the pt gets wet. It works over time, training the patient to feel their bladder filling up. Make sure the child does not feel humiliated, it is not their fault. 10% of 10 y/o still wet the bed. Other techniques like limiting fluids at night, punishing pt will not help.
