My son, who is now 6 years old, fell about 4 ft from a game he was playing at gaming center when he was about 3 years old. He slipped so fast I couldn't catch him in time and fell smack down on the back of his head! He lost consciousness for a few seconds and involuntarily wet his pants, but he came to within seconds without crying or complaining and he walked with me to the restroom to clean up. There were no bumps or bruises and he didn't show any signs of any developmental problems over the years, but now I wonder if his lack of bladder control could be related to that incident.
