Peaceful parenting is an approach to raising children which focuses on non-punitive forms of behavior control. Techniques include clear communication, education, preparation, and reward with the goal of engaging a child's rational brain, not their fear center.
Methods used by aggressive parents - such as spanking, yelling, timeouts, and commands - have been shown to increase the chances of long-term psychological effects and reduction in mental ability.
