The following comes from Steve Locker of Second Nature Sports about how parents influence their kids participation in any youth sport.
Here is a very logical (and simple) explanation on how sports work. Kids play because they are having fun. Kids quit because they are not having fun. Which scenario are your comments/actions/behavior supporting? If we allow our children to simply have fun, they will keep playing. If they are destined to advance in a sport, they must become their own motivators. When this happens, they are the first ones to know when they made a mistake and when they did something really positive. They don’t need anyone to tell them. Our job as parents of young athletes is actually pretty easy when you follow this perspective.
