Our 2 1/2 year old has been potty trained for months: at home; on days our; at friends; in the car.. everywhere. She uses her own toilet adaptation herself downstairs and a potty upstairs and a portable potty when we are out. She even wakes up at night sometimes to go. At the childminder's she wees down her leg at least once a session, sometimes twice at the moment; a problem that went away but has returned. She is super articulate and when I ask her why she says that the childminder gets cross with her about the toilet. When I ask her if she likes the childminder she says yes. Any advice would be super appreciated. Thanks. Devoted and concerned Dad.
