Not trying to a pushy mom since I would be VERY happy if DS is just above the norm.

Off topic - I grew up with a gifted kid. He was doing calculus when I was learning multiplication table. Needless to day, he excelled academically, but he had no friend at all because no one can understand what he was talking about. Then I realized slightly smarter than normal would be optimal IMO. Now, of course I am happy that DS is healthy and kicking!
