Since my last update we haven't had any more incidents. She has successfully used the potty several times. And just as often she has sat there for awhile and given up, only to fill her diaper moments later. She usually tells us when she wants to sit on the potty, sometimes it is our idea. It's a long wait before anything happens, but it happens.
We are still just trying to introduce her to the idea, so I would call this a success.
