Sounds like my son.  He is SWCah and I have never NOT let him participate in a sport he was interested in.  At 5 1/2, he has played soccer, t-ball, and swim team this summer.  he has taken more naps this summer...but hey!  he swims hard everyday and then we play at the pool for another couple of hours.  My non-cah daughter on the other hand likes the idea of sports, but just does not have it.  She plays soccer, but I think she likes playing with the girls and being on a team.  She is extremely artisitic and would rather do that.

I think you have to take your kids the way they come.  Don't let CAH limit their interests...regardless if sports are their thing or not.
