You didn't hurt my feelings!
See, I don't see unschooling as never teaching your kid anything. I see it as not asking them to do a math worksheet when they're not interested, or trying to show them how to build a cube when they'd rather be reading about dinosaurs.
If my daughter asks me to help her learn how to read, I'm going to help her. I can't imagine that unschoolers would say I should NOT help her? I should force her to learn on her own?
If you introduce an activity to a child and they think it's fun, I don't see how that's bad. I bake, I knit, I do crossword puzzles and jigsaw puzzles. I'm not going to avoid doing them in front of my kids! And if they want to help, cool. And if they don't, cool.
The other night DD1 asked what a brain was and what it did. Whew! Right before bed was not exactly the time to discuss that, but I did the best I could and DH followed up over the next few days. Then we were talking about having babies (for the record, she is never having them, she doesn't want it to hurt, LOL), and I mentioned that some people took medicine to make it not hurt so much. She wanted to know how that worked, so we brought up the brain again and talked about how there are cells in your body that talk to the brain, etc.
My point is that kids ask a LOT of questions. And my stance as an unschooler is that I will try to answer them, or help her find the answers to them, to the best of my ability.
I will also introduce things if i think she might be interested in them. I will not just notice that she seems to like pianos and music BUT wait and hope she figures out that she can ask to take piano lessons. I will ask if she wants to play around with a piano and maybe get a book that talks about piano music and how to learn to play it.
Before we talked about reading, she had it in her head that ONLY adults could read! If I hadn't mentioned that she could learn if she wanted to, would she ever have figured it out? Probably.
But to me unschooling is about knowing your child and understanding the way they think about things, and tailoring your approach to that. Not just leaving them alone all day every day to do anything they want. Certainly, most days we do leave DD to her own devices. But we also introduce ideas to her and ask her questions.
I know that is not PURE unschooling but so be it. Much of my philosophy might stem from the fact that my parents seemed supremely uninvolved in my interests. It was all up to me, but I was a kid and I didn't even know what was possible most of the time. (Who knew there were entire summer camps just for kids who liked to sing?) I want to let my daughters know what's out there for them and then let them decide what to try.
