Discipline should be more about teaching than punishing, according to Daniel J. Siegel, MD, and Tina Payne Bryson, PhD, authors of No-Drama Discipline: The Whole-Brain Way to Calm the Chaos and Nurture Your Child's Developing Mind ($16, originally $17). This book highlights the link between a child's neurological development and the way a parent reacts to misbehaviour, offering tools to stop the cycle of negative behaviour and punishment through calmly connecting with your child.
