Um--boys will be boys LOL. That picture is priceless!! I don't think there's much you can do except ice. Poor kid!! I'm sorry to laugh, you made my night. I remember my uncle did that with a suction cup to his forhead--OMG he was 40 years old, a business executive and had to work the next day. He even tried covering it with bangs (like a bad comb-over) and pleaded with my aunt to try to cover it with make-up. Don't know how that ended but I'm sure your little one will be just fine. I can't quit laughing!! (sorry)
