When I say sports, I guess I really mean physical activity. My DS is athleticly slightly above average but not physically talented. He does love organized sports - baseball, basketball, wrestling and he would play football too if I let him.
But even outside of sports, we try to incorporate some type of physical activity. He is not too old for the silly kids yoga videos. He loves to box on the wii. He and my husband play pick up basketball, we go for a bike or scooter ride, I have him run laps at the school, we go hiking or skiing on the weekend. He likes doing all sorts of physical activities and we encourage that to keep him well centered. I notice a behavioral difference when we have not been able to incorporate the activity.
