Hi, I really need some advice. My little boy will be four in a months time and has been potty trained for about a year and a half, including nights for the past six months. About two or three weeks ago he pooed in his pants by accident and since then he has only managed one poo on the loo, the rest are all done in his pants. He doesn't have accidents at nursery (school hours twice a week plus three mornings) only when he with me, sometimes in the house but sometimes out and about. I have no idea what to do or what is causing it. He just had a massive accident and I am at my wit's end. I calmly clean him up which is what i have been doing. i have tried telling him off but he got very upset so I didn't bother again it was too heartbreaking. I'm worried it will happen and his friends will notice and he will be teased. I also cannot cope with washing enormous poos out of his pants trousers and socks two or three times a day. he has had regressions with poo before when we were on holiday last year for example but nothing like this.Please help!
