6 yo DS has been dry at night for 3 weeks, bit suddenly he has set the bed for the last three nights and I can't work out why. We haven't changed anything, we limit the drinks he has of an evening and make him go to the toilet before bed. I even got him up at 11pm last night to go to the toilet and by 2.30 am he had set the bed again.
Does anyone have any suggestions on what might be causing this and what I can do please?
