For a very long time, people have been saying to me, "What if you want to do this approach with every kid?" For a behaviorally challenging kid, you're parenting this way just to help bring the kid's behavior under control and to greatly reduce conflict. But you want to teach all kids the skills that are on the better side of human nature: empathy, appreciating how one's behavior is affecting other people, resolving disagreements in ways that do not involve conflict, taking another's perspective, honesty.
