We just got the Potty Power video a month or so ago and it really helped change things around for our son. It has a skit in there about a princess deciding to use her "throne."
We also made up a chart where if he was dry and clean and eliminated in the potty it would move up a space (related to trains and a railroad... the tracks made up squares)- .30 was worth one pullup (and just kept it as he was only wearing underwear) and if we took him and he went he got one square. After about $7 was earned we would go and get him a Thomas toy. You can fix it to your own amounts. and find out what her currency is. Also she can help clean up her own poopy undies. I used some fabric paint to paint trains on his white undies... to keep the incentive to wear the decorated ones.
We started another chart ontop of the other one that was worth 3 squares at a time (called it fast track) if he took himself.. or said he had to go and we could still help him-- but the point is he would keep himself dry and clean and initiate using the potty on his own.. then he would essentially only need 7 squares to get a toy, not 23 if we took him each time.
He is pretty much on his own now after a month.
