So tonight DD asked me when she was going to bed about something a boy in nursery had on his bum. She said he pulled his pants down and showed her a worm then starts showing me her mini saying she doesn't have a worm! I've tried to ask how this happened and not got a lot of sense from her (she's 3) I think it may of been in the toilet but she said there was no teacher there. AIBU to be thinking they shouldn't be going the toilet together without a teacher and slightly alarmed by this?
