DS is 3 and has been PTed for a long time in teh day (nearly a year). I really don't think he's ready for night time training - and I certainly am not. But 2/3 nights he is soaking through his pull ups, and I end up having to change the sheets anyway. Sometimes he says it's happening just before he gets up, but sometiems he says he doesn't know when it happens (though logically it'd be mornings - or he'd wake up?) We've tried a few different brands and it doesn't seem to make any difference. Does anyone have any advice?
