Best of luck with your endeavor-- parents can definitely be the best teachers of their children; we traveled a lot when I was a kid and I was largely homeschooled from six till 13-ish, mixed with brief stints in schools in Spain, France, Denmark and the UK.

I'd say it was a success because I was pretty much college level by the time I went to an "actual" high school... and far more capable of thinking for myself.

All the best to you and your family.
