Wow, kudos to you for doing hte homeschooling route.
My DD is four as well. But she is after the cut off by a couple weeks, so we have another year of preschool.
Over at the moms group I belong to (SCValleyMommies.com) we have a few homeschooling moms who talk and like to get together. You should check the site out (it a free moms group!!)
