T.H.
Just a quick funny story. We were having some trouble with this as well. One morning while my son, approx. 3, was sitting on the potty my husband jokingly said if you start pooping in the potty I will bake you a cake. Well later that day my son pooped on the potty for the first time. Immedatly he asked for his cake. I had to call my husband at work to tell him he needed to bring home a cake. Instead of making one he stopped and got a premade decorated cake which we cut in to small pieces and for the next week we handed out poop cake everytime he pooped on the potty. I would never have thought something so silly would have worked when we had tried so many things and been so fustrated. Good luck
