My wife coaches 6th-8th grade girls' volleyball, and the local YMCA hosted a Positive Sports Parenting clinic. Really good stuff centered around this book:

Worth checking out for coaches and parents, as there are coaching clinics around this stuff too. Anyhow, all of you that coach, THANK YOU. And SheRa, your advice in one of the "teaching kids skiing" threads a while ago was great for my mini-mag, I wish she had you as a coach this winter, but we will be at WP.
