My just 4yo DS has been dry in the day for over a year but every single morning has a poo in his pull up. I think it's in his sleep and he just doesn't wake up. We've tried encouraging him to try to do a poo every time he does a wee, and giving him a treat when he manages but it doesn't seem to be v effective. And now he is trying to take his pull up off in the morning to disastrous effect - we need to crack this!
