Emma stands her ground

Today at lunch, I saw Emma defend herself. Her playmate was pulling her diaper and scratching and pushing her and she just kept saying "NO NO NO" while pointing at him. My baby. I kinda get the feeling she doesn't like her playmate as much as before. Kids are fickle but I guess Emma doesn't like being bullied. I know she is still to young to understand the different ways kids play, but as feral as I joke that she is, she is still a gentle soul.
