Speaking of smacking their heads!!!!

My 2 year old smacked his head on a sharp corner of our coffee table while running full tilt! You should see the size of the goose egg on his poor little head. I tried to put an ice pack on it to bring the swelling down but he said that was "owie".
I don't think everyday bumps and bangs can cause brain damage. A good knock to the head that causes loss of conciousness or bleeding though would be something to be concerned about. Don't worry too much about the little bangs.... there will be a lot of them to come, trust me!
