S.S.
Instead of waiting for a Dr to fix this later on when she has other issues in other parts of her body as a result of having a body that is out of alignment, try a rolfer.
Rolfing is a non-invasive method to help re-align the body. I was pigeon toed as a child as well. And as an adult it was hard to on my body to get this work done. If a child gets it done it is MCUH easier. She is doing it as her body grows so there is a very good chance that she will not have issues with it as she gets older. i HIGHLY recommend it.
