Kids got to injoy the sport. If you think its ok to smack your kid becouse he lost a match or didn't perform the way you thought they should your only going to make them hate the sport. The best year my son has ever had we took him out of a negative situation and went more positive. You hot heads need to remember these are kids and no one is getting paid for this. If they injoy what they do they will get better in the long run.
