D.T.
She is just not ready yet. She is very young, and the fact that she even knows where pee and poop go is a GREAT thing. When SHE is ready she will go on the potty. Just keep the potty near her when you are home so she is used to seeing it all the time. In a few weeks (yep, I said a few weeks!), ask her to sit on the potty while reading a book or watching a show she loves. She may just go and not realize it :) Then a big deal can be made and she will be so proud of herself and so proud that you are proud :) It is a wonderful achievement and such fun once it actually happens :) Good luck to you!!
