Jill -
Wow, your daughter's year sounds wonderful. Perhaps an early enterance to first grade would work best for your family? With subject acceleration in Math?

I can understand that your DH has some reservations about homeschooling with a backround like that! Are there any more attractive local folks who are homeschooling that your family could potentially socialize with, just to gently give him another view?

Whatever path you take, best wishes!
