well, I work from home. I'm not the primary breadwinner, but I could go back to work outside the home (my former field was nursing). The upside of nursing is that people work 24/7...
But when I work for myself, I don't need to spend 8 hours a day working...and like aculady is saying, so far, Butter sure doesn't NEED 8 hrs of direct education. We participate in a home study program like MegMeg mentioned...Butter has an optional classroom day for 3-3.5 hrs (if she stays for lunch) once a week...the only day we don't actually go to the school is Monday...she has her class on Tuesday, games club Wednesday, orchestra, multimedia and guitar on Th and 3 hours of art on Friday morning (she takes two classes of that). If I had to go work outside the home, I'd hire a college student as well, preferrably one fluent in a foreign language

or maybe you know a laid off teacher that would be happy to make some extra money.
I also agree with the comments about fighting with the public school or would the kid be better off just reading in a treehouse...mine would. Mine actually gets very little from direct personal instruction and would do just fine reading books about and teaching herself.
I think, if you think that is what is best for your child, you will find a way to make it work. I know if I was getting paid for all the time I spent arguing with our former school (and now maybe the home study school as well) I'd be RICH and not have to work anymore, lol!
