As part of the demonstration aspect of its service, the Child and Family Development Center of the Chicago Child Care Society developed a day care program for 2-year-olds. Because children who had been at ease with teachers and comfortable without parents became less involved with play and more clinging and demanding when additional children were later enrolled, staff decided to emphasize the group rather than the individual: All children, accompanied by their parents, would be enrolled on the same day. A model enrollment process was developed that gradually increased distance between parents and their children and varied the time the child spent at the center. Parents were expected to remain closely involved during the first 6 weeks. During that time, staff continued the pattern established during enrollment and operated under the general principles of simplicity, constancy, and familiarity. During the third year of the enrollment model, staff (1) intensified the focus on preparing the child and parent for the new experience and (2) established closer home/center communication through home visits, snapshots used to bridge the home and center environments, and videotaping of children's activities.
