Other than apologizing, I would just give him a bit of space. Being a kid is basically finding out what you like. I remember when I was younger, and all I really was into was basketball, tennis, and computers. My Dad still pushed me into little league, despite me not being able to hit or throw lol.
Still hate thinking of those days, as it was a chore just going out there to have him disappointed in how I played. Blah. Anyway, just try to get to know what his interests are, and if at this point it is too early, just try to do things with him (hockey, basketball, tennis, tap/ballet
hehe, etc).
He might be bitter about being sick and you pushing him, but apologizing goes a long way, and you have already done that. Sounds like you are on the right track on all fronts, so kudos.
