My 6 months old son fell off my bed a week ago when he was sleeping in the morning. The height of the bed is about 20 inches, the floor is hard wood floor. He cried a little bit after the fall. After the cry, everything looks fine except there s bump on the head where it hit the floor, I guess. It seems like pain for him because when he lying on this side. But just one day, he didn t feel painful any more when you touch the bump area. He didn t have any vomiting after the fall. But the bump got bigger today. We didn t go to ER because he shows normal. Does he hit the bone? What s the reason for the bump? Will it go away?
