Amy, I am sorry you are having a tough time with this! I really think the range for training is wide and that different things work for different kids and many just like to do things on their own time.
I would keep encouranging her, but don't push it. She just turned three so I don't think a ped would say you should start worrying.
Have you tired just dumping the diapers in the trash? Maybe she just needs closure? :-)
Delaney got big kick out of announcing in the store by the diapers aisle that she didn't need them anymore.....
you never know when it will just click for them....be patient, she's gone on the potty before, she will again!!!
