Brianna and the potty

We are starting the process of potty training even if we didn't want to with Brianna. Last Thursday evening Kalen was giving Dylan a bath and Brianna went to Daddy and said, "Daddy, poop potty", and got the insert that she sits on. We were amazed. She did it and all by herself. We reward her with ice cream. She really isn't into anything besides ELMO and Nemo so I guess I'll have to go get her stickers for future trips to the potty. So if any of you parents have ideas on how to make this something consistent please let us know:)
