I use to teach kids English. One of my co-workers had a child hit his head on a bookshelf. He seemed ok at first, but like 30min later had to be rushed to the hospital because of convulsions. Serious stuff getting hit in the head.
Insurance sucks, but kid + bad publicity means maybe they won't drag their feet.
Best wishes to you, your son and your family.
Thanks @rt395 yeah anything to get the ball rolling.
