Free Range Kids
Free range kids, or free range parenting, is a movement which believes that children are too coddled, and advocates more autonomy for children. It was popularized by pediatrician Benjamin Spock, a book by Lenore Skenazy, and The Coddling of the American Mind by Jonathan Haidt.
The movement protests modern rules and cultural practices that encourage overprotectiveness of children, in favor of allowing children to take controlled risks. It advocates, for example, giving autonomy, allowing children to play unsupervised, and in environments that superficially appear dangerous. It believes that children will grow in competence and character when allowed to sometimes function independently.
An important concept that supports the movement and discussed by Haidt is antifragility, the concept that things can be strengthened by exposure to risky situations.
