My DD had her trial session at her new nursery today (2hrs). When I went to pick her up I could smell she had had a poo.... when I changed her at home the nappy was full to bursting point and she had dreadful nappy rash. I am very concerned the staff had not noticed and changed her. She starts officially on Monday, do I say something, or give them the benefit of the doubt. I really don't want to come across as a moany mum from the start. Any suggestions?
