The document discusses two important needs in children's development: the need to belong, which grows from the need for security and involves being an accepted member of a group, and the need to love and be loved, which is first learned from family and leads children to seek stories about romance. It notes that if a child feels unloved, they may become suspicious and antagonistic towards others. The document encourages providing children books about people of different backgrounds to help them identify with others and feel a sense of belonging.
