If I can supply him with some resource, experience, etc, that is in line with what he wants to know, then that is great.
I don’t attempt to force him into any knowledge, because that kind of prodding takes his authority over his own education from him and also makes learning seem like a chore. So far he is learning to read, write, and do numbers all on his own volition (we of course encourage these things, read books, and play numbers games if he wants to), and I cannot think of anything necessary to a happy life a child would not learn on their own.
Summerhill School in England is living proof of this for decades now.
It’s a good question though. Thanks for asking.
