We're unschooling for now, but I don't know for how long we'll do it. I'm not emotionally invested in doing it long-term or anything, but I have no idea how (or if) we ever naturally transition out of it. I cannot imagine sitting them down and saying, "Ok, now do math." I don't know. I'm just playing it by ear and pretending to know what I'm doing, I guess.

I'm keeing my mind open to whatever feels right and works for each kid.
We do unschooling, because my kids seem to teach themselves (and each other) and they're pretty resistant to instruction or being worked with. They keep themselves busy for most of the day, so I don't like to interrupt them. Like, earlier this morning, they went on a trip to England and now they're making a birthday list for ds2. Whoops, they just moved under the dining room table and ds1 says it's a museum. Then, they'll run back upstairs and drag all the dolls or trains out and there will be some dramatic scenario there. I don't know what they do many times, but they are very very busy. So, it seems wrong to stop them from what they do to do something else. I'd have to flag a kid down anyway.
My oldest has some specific academic interests, so we do follow up on that and we like how he gets exposed to a lot of "subjects" by that method. Last year, he was obsessed with space (still likes it this year) and we did science, math, art, poetry, music, and history all because of that. Some of it was unintentional and unavoidable in the way of questions and conversation. Some of it was planned (e.g. MIL bought him the classical music for planets, I did a planet felting craft with him). Right now, he is obsessed with engines and is curious about volcanos. There's a lot to do there, lots of possibilities. We might make a vinegar/baking soda volcano next week; that should be huge with both kids.
Anyway, unschooling really works for us for now. I like for the kids to direct their own pursuits and I want to reinforce that natural motivation esp since I came out of school with no work ethic. I like the freedom and spontaneity that comes with it. I like watching them spend entire days playing. Ds1 would go to kindy this August and I cannot imagine him being away from his toys for 7 hours a day. I guess it's kind of shocking to me that while his same-aged cousin is sitting in circle time or doing a worksheet, he will be running through the house in his pjs playing with trucks. I like the extended relaxed childhood it provides them and I like that, academically, we wander all over the place based on expressed interest.
So, we'll keep doing this until it appears to not work anymore.
