Your child gets hit in the head and falls to the ground, unconscious.
Wrong response: Take him to the hospital.
Smart move: Call 911. He could have a spinal or brain injury, and moving him could make the injury worse, says Anne Stack, MD, clinical chief of pediatric emergency medicine at Children's Hospital Boston. Make sure that your child is breathing and that he has a pulse. If he doesn't, start CPR immediately. Otherwise, shake him very gently and call his name to see whether he'll wake up.
