My girl will sit on the toilet no issue she loves her underwear’s we have no accidents during the day but she is TERRIFIED to fully pee on the toilet she will let out little trickles no issue but screams cries and even hits when she feels she has to pee , she will hold it for hours to avoid going on the toilet , I’ve tried bribing her with snacks or anything so she will pee but it’s been a struggle . We’re currently on day 3 . Anyone have any advice ?
