A child 's family is the center of his world during infancy and extending into the preschool years. As a child nears school age and in succeeding years, he reaches out into the world beyond his home environment. He comes in contact with the world of other people who arc not included in his family circle. In this new world of peers, the child finds something he does not find at home. Here are other individuals like himself who have many things in common, such as age, appearance, interests , and desires. We find in this peer culture, children who can better satisfy their growing needs of self-identification and social adjustment by being in a neighborhood gang or just playing together than they can in the home environment alone. Association with peers is an important supplement to a child's associations in the home.
