It is a problem in all sports. I've seen coaches who have let their own kids quit baseball and soccer. It should be a choice the kids make themselves, whether or not they go out for the sport. I tell my kids that I don't care what sport or activity they are involved in, but that they will be invovled in something. I beleive in the old saying that "Idle hands are the devils workshop so to speak". Kids that have too much time on their hands are the ones that get into the most trouble. I also enforce keeping to comittments. Meaning that once my kids start a sport or an activity, they are comitted to it for the duration of the season. If you let them just quit whenever they feel like it, they will never learn anything. I also try to lead by example, meaing that I'm there with them at every practice and at every tournament if it within my power. the key is consistancy.
