If done correctly even at the youngest ages baseball can be a good thing.
The problem is when pressure is put on the kids. When that happens many kids will shy away from baseball before they even have a chance to fall in love with the game.
I know it is preaching to the choir here, but those in charge of the youngest kids playing baseball, need to make sure it is a positive experience for every kid. That takes some work and creativity at times. When it is all said and done, if those kids you have worked with or coached end up loving the game... You have been a great mentor!
It has long been my belief that creating baseball fans is far more important than creating baseball players. If you think about, they go hand in hand. So the worst thing anyone in charge of young kids can do, is give a reason to dislike the game. That could even have a generational effect.
