In preschool, learning to stay within eyesight of the teachers in the forest, a place where there are no man-made boundaries, fosters both independence and self-control. Instead of being confined by a fence, the children learn to adhere to natural borders, like a fallen log, a creek, a steep hill, and so on. Of all children, none seem more apt at mastering their environment than the children who go to nature-based preschools.
