I wondered if anyone has experienced anything similar. Up until about a month ago she was fine having her nappy changed but now she will keep denying she is dirty and gets really upset. I've tried reassuring her that it's ok. She moved classes to 2-3 year olds at nursery at about the same time, and though I've asked them if something happened either with her or another child being upset they say no. She was absolutely hysterical when I changed her earlier which is totally out of character for her. It also doesn't happen every time. Hate to see her upset and also don't want to make things worse. Any advice?
