Also regarding to reading... how sensitive is he to feeling like being a trick pony? DH and I suspect that DS is very sensitive to this and focuses a lot of energy into blending in - we had no idea he could read until months after his shadowing day at the GT school at 3.8, and they said he was reading words off the wall. So DH asked him and he said "I just wanted to surprise you." So we don't push him. Even today, with books I know he can read, if he wants us to read, we just read - and have not pushed him to read to us.
