OP here, first off, I'm glad this got posted. I was at the game and the little girl was about 1 or 2 years old. For the entire game she looked happy as can be, until I smiled at her. Her face went from the happiest on earth to the saddest thing you could find. Just the change of emotion made me feel terrible. But yeah, probably just another child being a dickhead now that I think about it.
