Before you call Child Protective Services on us I can explain.
She is learning to walk up and down stairs on her own. Alex hangs out with older kids, and she wants to do EVERYTHING they are doing. She fell 2 days in a row, and both times, her face broke the fall. Clearly, you can see from the picture, that her pupils are the same size. No need to worry.
The funny thing is, I don't think she knows that she has "owies" on her face because she can't see them. Her favorite thing to do is to point out all of MY owies and make a big fuss about them. She always looks for owies on herself, but can never see any.
