My son was dry throughout the night for a long time..(occassionally wetting the bed at night),but every since he has gone back to school,he has been wetting the bed nearly every night..I've been getting him up at night to go to the loo,before i go to bed ,but by morning he has wet the bed again..My husband is getting angry with him but I'm staying calm as i don't want my son to get upset,what can i do?My son is 7...should he still be going through this or could there be something wrong????
