I'm an unschooling flunky. We made it till Thursday, and I couldn't take it anymore. The main irritation for me with living an unschooled life is that school is never done. You're always learning. Sometimes a girl just needs to say, "finish your schoolwork and then you can play on Lego.com"
And though I enjoyed playing and interacting with my kids more than usual; I need a break. I cannot always be "on". They need to do their own stuff, and I need to feel like I can check something off my list.
I do think that unschooling is a viable alternative to traditional education, or traditional homeschool - that is if you can stand it.
