who sits on the potty?

We have a great book that goes through... "Does a zebra/sheep/giraffe etc. sit on the potty?" AB loves this book and loves to answer "no, no" to all the animal questions. Well - suddenly, as of this week, AngelBaby sits on the potty! She has been out of diapers during the day (other than naptime) and is doing a great job of going to the potty on her own when she needs to, and most times agreeing to try when reminded. We have a sticker chart on the wall in the bathroom and she is doing so well! :)
