FINALLY found som eshoes that she doesn't automatically scrunch her toes up in. But they are size 1 and she is a size nb or 0. Oh well. Gotta start where. EIT officially declared she is sitting up!
First day with new shoes as per the PT. They are soft and don't fit great. They're newborn size and her feet are small in them. The kind she really needs doesn't start until size 2 :(
