We started potty training at about 28 months. DD can use potty & loo for wee, but still persistently poos in her pants. We've it seems like we've tried everything and every time it seems like we've made some progress, she regresses. Both myself and my husband are beyond stressed about it and the prospect of her going to school and still not being potty trained is worrying us even more. Any advice would be VERY gratefully received.
