Have you tried sitting on the big potty while she's on the little potty, or tried rewards? Rewards can be many things, anything that she likes, and it doesn't necessarily have to be a food. Also you might try big girl panties instead of pull ups, if she doesn't like being wet in the pull up I can guarantee she won't like being wet in "big girl" panties. I don't have any children myself, but, was a nanny for two 2 year old boys (trained them) and a 4 year old girl and also witnessed my girlfriend train her daughter. She did the reward thing, number 1 was pretty easy for her number 2 was a little more challenging. If these things don't help I guess just be patient and it will happen when the time is right for her. =o)
