Unfortunately, the answer to this question is, because of you. Your children are what you train them to be. You are their primary influence until their early adolescence. While each child has his or her own temperament and personality, they learn socialization skills from their parents. Rudeness, inconsiderateness, and aggression are all caused by inadequate parental supervision. The most important variable in raising children to follow rules and to be respectful of others is consistency. Children need to know that there is an older person who will watch over them, and who will set limits on their behavior. Meeting out consequences for unacceptable behavior is as important as providing for food and shelter. Parents mistakenly believe that their children will not love them if they discipline them. Actually, the opposite is true. One of the fundamental developmental tasks of children is to learn that they are not necessarily the center of the world. They will need to learn to respect the rights of others. This is why play groups and day camp are so useful in socializing children. Take the time and effort to discipline your child.
