I love the community aspect - hearing from others who have similar ideas about child led learning is such a pleasure. It is also valuable to hear about the various directions people can go when they start from the place of following their child's interest. I also like that the content provides a structure to my rather drifting and unfocused approach to learning that doesn't conflict with my beliefs about learning being something that should and does come from within the child.
I think the most impactful thing I've learned has been the simple act of actually creating the learning journal and having the intention to write down questions. It gave me just a tiny bit of structure from which to support my son's curiosity, and I think it gave him the feeling that his questions and ideas were being honored.
