D.P.
My son is five we had that problem and has increasingly gotten better. First we limit his drinking like no drinking anything after 7 pm. Made him go pee before he went to bed. Weve chewed him out after him doing it every night and so he got better about getting up himself and going when he needed to. I know sometimes he sleeps to hard and cant wake himself up. We let it slide once but like if he does it two nights in a row we disipline him. He down to maybe having and accident once or twice monthly.
