Hi M.!
It sounds like your son loves being active and I think that is great. Most kids would rather sit in front of the tv and play xbox or ps2, rather than run around. I think, as long as your son isn't complaining about having to do so much, then I would keep him in golf and soccer. Let him try everything and anything he wants while he is still young and as he gets older he'll be able to choose one or two sports he is completely interested in pursuing. Also, you are very lucky that you only have one practice per week! Our 6 yr old son has football practice 3 times a week and our daughter has soccer 2 times a week plus an optional 3rd per week and all their games are on Saturdays, meaning we are running from one game to the other. Just have fun with it and support him in whatever he wants to do.
Take Care!
D.
