Today's headlines about the actions of twenty-first-century children tell us that they are in distress. Unusual behaviors surface as disobedience, failure to learn, anxiety about socializing, excessive excitability, and inability to follow directions. What can parents do? In this guide, Dr. Maria R. Burgio reminds parents that while many behavior problems are part of growing up, they must distinguish between normal behaviors and those that require help. She explains how children normally develop from infancy through adolescence and provides worksheets for tracking behaviors and identifying problems outside the normal range. Dr. Burgio also identifies the special challenges of parenting twenty-first-century children, discussing topics such as sexual activity and substance abuse in children and adolescents, as well as how social media can effect social development. As a twenty-first-century parent, you must get the information you need, for a wise parent is the key to a healthy child.
