Your DS is young, right? Early primary grades? What can go "really wrong" at that age? Worst case scenario? Homeschooling is a dismal flop? Well, he can go back to public school. There's very little long-term risk involved in homeschooling because it is reversible. And early primary school truly is not rocket science. If you can do math, read directions, and write complete sentences, you can make it work for your child. Remember that you don't have to know all the answers. No second-grade teacher knows all the answers! If you can parent your child, you can homeschool him.
Actually, he's 9 and in 5th, so he'd be 10 and starting 6th when we'd be doing this (next year). I know what you mean about the early primary grades though, I'd be totally ready for those, LOL! Thanks for the links, I'm off to check them out next.
I'd be happy to tell you more about the parts that are actually hard sometime...

Do tell...I'd like to hear the bad with the good, so to speak. Thanks for your input.
