Six papers focus on aspects of the Macomb (Illinois) 0-3 Regional Project, a rural home based program to assist parents and their handicapped and high risk infants and toddlers. The first paper discusses the role and operation of home visits, with emphasis on the functions of the child development specialist (CDS). The second paper describes the project's undifferentiated staffing patterns, while the third examines the use of a mobile unit in delivering services to rural areas. Cost information for the unit is broken down. The origin of the baby buggy as the project's logo is recounted in the fourth paper. The development and implementation of activity plans in home visits are considered in the fifth paper, while the final paper addresses the issue of toilet training. (CL)
