Parents and teachers are not the only people who will play an important role in your son's life. Your boy needs friends. He may begin with one or two, perhaps children from the neighborhood or preschool. When his school years begin, he will gravitate toward friends who share his interests. And by the time he is in high school, friends have all but eclipsed parents in importance. Understanding how a boy forms friendships (or fails to) will help you support him as he enters the world of his peers.
