According to the National Center for Education Statistics (2001), there are over 21 million children under the age of six in center-based child care programs in the United States. Programs vary in their content, but one of the aspects common to all is the social context in which learning and care occurs. All early childhood teachers have a tremendous responsibility to meet the developmental needs of the whole child, and more than that, to help children develop the prosocial skills necessary to succeed in a group setting, as well as in society.
