Molly was potty trained about 3 weeks b4 she started preschool (she was in a full body cast right up until them so it made it impossible). we had been trying b4 the cast went on but she was very similar to your daughter, was interested but then would get upset if we put her on the potty or toilet. but when we started again just b4 she turned 3 it was a breeze, it took 1/2 day and she hasnt had an accident since - so my suggestion would be to just wait a few months and see how it goes...hth
