Such a great post, @purplemoon! You should teach whoever and whenever the opportunity arises. The 12 year old should catching quickly. I don't think all childcare suitable for home schooling and not all are suitable for public and or private. Each child is unique. I'm homeschooling my 14 and 8 year old.
I'd actually like to be able to talk more about homeschooling with you and your ideas. You've always been progressive in my opinion and in the right path with things.
Great Thoughts you have here and you'll do fine teaching! 💙
