DS was potty trained in February and quickly went dry at night too. In the middle of July he started wetting the bed again - at least every other night. I am against putting him back in pull-ups at night because I want him to feel that he's wet and that he's not supposed to do it. Luckily the weather's been OK to dry the sheets!!
Also over the past few weeks he's been having slips in the day, so much so that he looks as if he doesn't even know it's happening. He's not drinking much at night and I don't think he's in any pain so am ruling out an infection. He is a 'busy' little boy so don't know if he's being lazy during the day or not. Any advice for the night would be gratefully accepted though.
