If it isnt a deliberate thing then why is the pullup dry at times and he says 'mummy i did wee in bed' ..... he doesnt do this everynight so as i said when he has a dry night i praise him up and when it seems like a true accident it doesnt bother me BUT when he comes into me in the middle of the night with dryish pullups on but his bed is soaked ummm im thinking it must be a behavioural thing to get into mums bed.
And he has slept in my bed without a nappy on at all and not wet it and got himself up to the toilet in the middle of the night so i dont know what to do .... he is a very strong willed child as well
