How to Coach Your Kid
It's so much easier with someone else's child, isn't it?

Edited by: Liesa Goins  
 
Chances are good your kid isn't the next LeBron, A-Rod, or Deion, but
raising a kid to love sports is priceless. As his first coach, you have a
huge impact on how much he enjoys sports and likes himself. Follow these
tips from Rick Wolff, chairman of the Center for Sports Parenting, and Joel
Fish, Ph.D., author of 101 Ways to Be a Terrific Sports Parent, so you don't
screw up a kid's love of the game.

SKIP POSTGAME ANALYSIS
When the thrill or agony of the game is still fresh, he doesn't need you
harping on him. The only challenge he should face: sugar or waffle cone?

tell him it was worth the price of admission. "Kids want to believe parents
feel proud of them," Fish says.

If you want him to stop being a ball hog, wait until the next practice and
say, "You're a great ball handler [praise], but if you could dish off when
you're double-teamed [constructive criticism], you'd be unstoppable [praise
with incentive]."

If he stops wanting to go to practice or starts picking grass in the
outfield, there could be a lot of reasons. He's the best source. Say, "Help
me understand," Fish suggests. You're acknowledging the situation without
claiming to have the answers or giving him the third degree.

WATCH YOURSELF
In the stands, meet with other parents and agree to call each other on
offensive behavior-pacing, grimacing, arm waving. Your kid will notice this
stuff, and it'll suck out all the fun he thought he was having. All you need
to do is cheer
