Take heart; no child starts the first day of school wearing diapers. This too, shall pass. I have two suggestions - I recommend only trying the one you know will appeal to your daughter. One is to put a very lovely bowl of very delightful candies on the toilet. Instruct her that every time she uses the potty, she may have a piece of candy, no matter what time of day, no matter if she's had breakfast, no matter what, every time she chooses to use the potty, she may take a candy. After this is well established (say 2 weeks), tell her the day prior that you know and she knows she is fully capable of using the potty and starting tomorrow, she is expected to use the potty.The second suggestion is similar except use dollar store toys wrapped up pretty and placed in a basket on top of the refrigerator. She gets to pick a toy every time she uses the potty.These aren't bribes; they are goal incentives. Bribes try to get someone to do the wrong thing. A goal incentive works to promote positive actions.
