Your son is very advanced for his age and sounds amazing! Re: school, I would recommend that you start doing your research on all available options. When i was in your situation, the wise folks on this board recommended play based school. My dd is 4.5 yo and has thrived in a play based school that has zero focus on academics. Since Your son picks up things on his own, you may find that he learns a lot more in an organic setting than a structured one. Also multiage classrooms might work as he will get an opportunity to watch the older kids and learn through osmosis. Montessori schools might also work depending on how flexible they are. At home, keep doing what you are doing now in terms of following his lead.
