My 4 year old boy is fully toilet trained but wakes up very early (anytime between 4.30 and 6.00am) for a morning poo. This is making him (and mum) very tired and wondered if anyone had any ideas how to alter the time? He does wear pull ups in the night but does not want to poo in these as he wants to use the 'big' toilet, the same with using a potty.
