Future Ballerina?

Peyton loves standing and walking in her walker, but ever since she could do either of these, she's had an interesting way of doing either of these. She stands on the tops of her toes, not on her tip toes, literally the top/upper party of her foot. I tried putting shoes on her feet to force her to stand on the bottom of her foot, but her feet are so little, it's hard to find shoes that fit. She wasn't a big fan of the shoes, and I couldn't tell if her feet were actually flat inside of the shoes (I had a suspicion that her feet were actually pointed inside of her shoes and she was still walking on the tops of her feet). She's getting a little better about standing/walking on the bottom of her feet and probably only does it about 50% of the time now.

Doesn't it look so painful; I don't understand how it doesn't hurt her to do this. I guess she's just training to be a ballerina!
