I am writing this on behalf of a friend.
Her just turned 5 year old has been toilet trained for almost 3 years now - however about 6 months ago he got lazy and started having accidents - ie would be playing and someone would realise he'd pooed or wee'd himself.
We wondered if it was to do with big school as he once mentioned that boys that had accidents couldn't go to school, but that doesn't seem to be an issue - he will have the occasional accident there but for the most part is dry.
Friend mentioned that the other day they had a big day out and he was fine/dry all day yet 10 minutes at home and he wet himself!! He doesn't seem to care when he has accidents and rewards/sanctions don't seem to help.
Any ideas.
