3.5 year has been fully potty trained for a year. He is a v easy going kid and was easy to potty train - no accidents really and took himself to the loo independently for a year.
A couple of months ago he became constipated - no idea why. He started holding onto his poo and not going. Then he started pooing in his pants. Or if just poo himself a bit, so i would smell something and then realise it was on him. It's like he has no control or knowledge of it coming. He gets upset a home about it - he says "I don't know why it happened" and just cries. He hates it being on him
It started at nursery and he's doing it nursery but doesn't tell anyone is has happened.
I've taken him to a GP and they gave him laxatives saying it sound like he had chronic constipation. It actually worked the first time - and for the first time in 2 months he told me he needed to the loo, went there independently and used it - he was so happy withi himself and said 'mummy the medicine worked' but i kept using it daily for the last week but he has gone back to poo in his pants, all over him, he crouches in the corner of the room crying
the nursery are trying to say they can't handle it and asked me to sign something to say they hvae a right to exclude him.
any advice at all? He really really doesn't want to be doing this, but it' slike he has no idea how to control it anymore.
