Curv,
Good Luck. I coached T-ball as well, for my son when he was 5-6. The kids were just the greatest pack of little eager-beavers I ever saw. I had a great time playing with them and seeing the look on their faces when they accomplished something they had been working on. You'll never beat how you feel when you've given that moment to a little one. And you'll nevber forgt those faces, either.
I agree that it is imperative to keep the heavy competition off the radar completely. There is plenty of over-the-top hostility and competitiveness to come if they stay with organized sports. Let them, for Pete's sake, have an experience that's just plain fun. We organized our league to provide playing opportunities for each and every kid...no draft, no cuts, no benching anybody other than to wait for their turn. Remember, they are just tiny ones, and really only want FUN. I considered my biggest obligation to be fending off parents who were just around-the-bend about playing time, drills, points, scores, winning, rank, etc...They simply don't understand that they (the parents) will never, ever play pro ball...but they expect little Johnny/Jane to be the next DiMaggio. Trust me, they'll tell you exactly how it'll work out, and how talented the little squirt is. They will abuse you at every turn, for things you simply can't fathom. Parents are why I left and refused to return.
Keep the drills simple and interesting. Keep the kids laughing while they learn. Make sure they cheer for and encourage each other all the time. Play for points, but not to win. At that age, there can be no losers.
And get ready for the funniest stuff you ever saw...
Kids hits ball, rounds first, heads for second...pauses, has a thought...drops trou and keeps running straight from second to the portable toilet at the other end of the park...and never looked back! Whistle up the kids Dad, and send him off to chase down junior and return him to second so he can finish his run!
Kid hits ball...finally!! ...and takes off for third, running the bases backwards. This one took a while, as they all tended to run to the first thing they could see, which was third!
Or my son...supposed to be playing outfield. Kinda dull out there. So when the ball finally came his way...he was literally chasing butterflys and singing to himself. I still laugh when I think about it.
I hope it's a great thing for you...you'll at least have a few laughs along the way.
