Part of a series on early childhood demonstration programs designed to improve early parent-child relationships, stimulate positive child development, and prevent later behavior difficulties, the pamphlet describes a Toy Library project for low-income families in Washington, D.C., which, in addition to loaning books and toys, offers a wide range of child development services and activities. Toys loaned are designed for three separate age groups: infants, toddlers, and 3 to 5 year olds. Among the activities offered are such things as afternoon workshops for parents and their children, first aid courses, cooking demonstrations, and films and discussions on early child stimulation and family health. Other program aspects discussed include staffing (a head librarian, a library assistant, a library aide, and two volunteers) and supplies and facilities. A study of the program's impact indicated appreciable changes in the participating children's behavior, such as better speech, more interest in reading, and greater curiosity. (DLS)
