When you watch ten-year-olds intensely defend the rules of their games, you see what a deep need this is early in life. It structures children's universe and gives them foundational meaning and safety. We cannot flourish early in life inside a totally open field.

Chaos and chaotic parents will rightly make children cry, withdraw, and rage—both inside and outside.
