My 4 year old daughter has been going to toilet fine for wees since September. She s never done a poo. All of a sudden she keeps asking for a potty, won't use the toilets at nursery and keeps saying she's needs a poo so she can get a nappy on but then just has a wee. I picked her up from nursery today and they said she had been crying all morning. She told me it was because she needed a poo and cried all the way home where she rushed into the bathroom and just did a wee in the potty. Not the toilet. I just dont get it.
