Hey, don't underestimate your kiddo, mine actually appeared just as yours did, in fact, not nearly as smart seeming from what I can recall, and finally she gets accepted into gifted program in 5th grade and all of the sudden shes cranking out high percentile SAT scores, perfect standardized testing scores, and college reading levels. In 1st grade she was just "another bright kid." Now shes gifted and possibly HG. Don't worry about it! It sounds like you have a really bright kid, and if you can get him (him?) involved in gifted programs early on when he's blossoming, then he should be set up for the rest of school. Good luck!
