My 22 month old daughter REFUSES to use the toilet or her potty. She recognizes the feeling and can stay dry for 3-4 hours but when she can't hold it in any longer, she starts dancing around and crying for a diaper. The first 2 days of training were great but now she won't do it. When I sit her on her potty, she screams and cries and yells "no potty!" What happened? How can I help her? When she sees me go she'll applaud me. "Yay, Mommy go potty! High five!" lol Any advice?
