it's been a continual dance of stepping back, reevaluating, stepping back more in some places and forward in others. We always involve them in decisions made for the family and for themselves.
We ask the kids for feedback on what they think can be handled better, and we set goals together for things like keeping up with the housework which affect everyone in the household.
As they get older, they have asked to learn specific things, and we've offered curricula, textbooks, online learning programs, etc. My 15yo is learning French, for instance, and she's got a 150-something day streak on the DuoLingo app.
My oldest searched out Khan Academy, a free online resource which teaches things like algebra and world history thru videos. He completed a lot of those programs because he felt like he wanted some structure, and wanted to make sure he wasn't missing anything major.
When my 15yo was about 12, she went thru a phase of "feeling dumb", and felt like she needed to go to school. We talked about the many things that were driving those feelings, and one tangible thing that worried her was that she felt like she knew nothing about math.
We found online videos for her, fun lift-the-flap books on fractions and decimals, workbooks, and even the old school primer texts from the 1850's that are full of nothing but word problems.
She pored over those things by herself, and then asked for help, because "she wasn't getting it". When I went to help her, it turned out that she was second guessing everything because it was all so easy she thought she must be doing something wrong. "All my friends think this is hard--?!"
Yes, go for it, and just keep going! Unschooling is full of ups and downs, and sometimes the payoff of "evidence that it's working" doesn't fully show up for many years.
It's so worth it, all the same.
