I'm not sure if this is relevent to your situation, but I was just reading an article by Deborah Ruf about boys in early entrance situations. http://www.educationaloptions.com/news_Apr_08.htm#one

Certainly, not all boys are going to have problems in an academic setting. But I found it validating in that it suggests that just because a kid is quite gifted, it doesn't mean that early school is best. But sometimes a year of hanging out at home and playing with parents and neighborhood kids can be good for a kid.
