You can call it hot-housing.... We refer to it as feeding the monster! My DS was insatiable at a very early age. He was reading well before two and just as PTP suggested, it didn't seem to make his teachers "get him". In fact his first pre-K teacher viewed him as a PITA, because he refused to conform.
The rule in our house has always been to answer his questions and give him what he wants as far as learning is concerned. Because of this, my now DS8 has an excellent understanding of subjects that many never learn at all. He has chosen many things including mythology, economics and greek. To those that would call it hot-housing, I'd like to see them live with him for a week or two!
