My 3 year old DD has recently moved up a group at nursery. In the room she was in before there were child sized toilets and she was fine using them. In her new room there are adult sized toilets and she is scared to sit on them. In addition, the lights in the toilets are on a motion sensor so it's dark when you first go in, which scares her. There is a potty available for the children to use but I've seen it full of wee on occasions so they aren't always emptying it after each use which I'm unhappy about. I've therefore brought in my DDs own potty from home, but other children have been using it, which upsets her. I'm worried all this will set her back with her toilet training and she'll hold in her wees and either wet herself or get a bladder infection. Any advice as to what to do please? Thank you.
