Dd potty trained brilliantly in June with very few accidents. Over the summer, we had a regression with poos (she goes in her pants - she seems to know as she goes and hides. We have occasional poos on potty/toilet). I had DD2 2 weeks ago and she is having accident for both unless we physically take her to the bathroom. We have tried rewards, sticker charts, chocolates, gifts, praise, songs and rhymes. At nursery she is managing better with wees but not with poos.
Advice?
