Youth sports coaches and parents should set realistic, age-appropriate expectations for athlete [1]s [1], which requires an understanding of child development, and being child- rather than adult-centered.
Coaches and parents should be aware that:
A good youth sports coach is also child- not adult-centered. He or she understands that the game belongs to the players, not the coach or parents, and that the players and the game should be focus, not the coach. A simple way for a coach to do that is to periodically ask him or herself, "Whose sport is it?" The answer should be the same every time: the athlete's. A coach is there to guide, motivate, help, teach and inspire, not to control or to gratify his or her ego.
