What a wonderful thing, OP! You MUST explore this motor and rhythm skill of his. Get him into music as well, not just dance, gym and althletic pursuits.
Also, please do another evaluation in a few years. Cognitive and developmental assessments in very young children sometimes get it wrong. My kid, who was born very premature and had a global developmental delay, was not supposed to graduate high school, let alone graduate with a killer GPA and near perfect ACT! Yet he did.
