Not every sport is appropriate for every age, so it's important to select one that is safe and suited to your child. Because they become discouraged with a game that is inappropriate and frustrating. The kids just follow the ball around. They aren't yet at a level to strategize team plays. This sport is okay as a social game, but kids under age 11 usually can't hit the high basket.
Basketball requires good endurance and a high skill level.
Contact football generally is not dangerous because the children's light weights don't generate a lot of force during collisions. Football is a complex set of skills and kids may not be ready for organized teams until at least 10. Children begin to learn to kick the ball between 3-5. They need good endurance and should learn the basic skills of kicking and dribbling before starting organized competition. In all sports with preadolescent children, the emphasis should be placed on having fun and building skills rather than competition.
