My definition for unschooling is "creating and maintaining an environment in which natural learning can thrive."
The environment I’m talking about—what we sometimes call an unschooling nest—is not just the physical home, though. It’s the relationships within the family, and the exploration of the world outside the home by parents and children both. The emotional environment is crucial—the relationships.
There’s another good piece of advice in general— not just about unschooling, about anything you want to learn.
Read a little, try a little, wait a while, watch.
