Huh, that's the first time I've heard of unschooling, it seems like a really cool concept. If you don't mind me asking, where do you live and what are the laws like around unschooling there? How are people's reactions?
We're in Arkansas now, having moved from Virginia at the end of last year.
Virginia requires a Notice of Intent to be filed with the local school district and periodic standardized testing - there are some way around each of these things, but that's the course that the vast majority of homeschoolers take. It's annoying but not onerous.
