or should I wait till he starts having the ocassional dry nappy in the morning?
He goes into such a deep sleep that he wouldn't waken to go to the loo during the night. He can go for hours and hours during the day without needing a wee - so he has the capacity in there!
His nappies are still wet every morning - is it a case of letting him wet the bed for a few nights till he 'learns' to wake up for the loo? I'm not convinced he'd even notice - he's been wet a couple of times before(when his nappy came loose) and if anything, he sleeps even longer in the morning!
