This report describes a one-year feasibility study to design a functional child development model for infant day care in Hamilton County, Ohio. Mothers of babies under 18 months were interviewed by telephone to determine use of and interest in infant day care. Assessment was made of existing resources for full time day care in the county (location, capacity, costs, programs and support services) and needs were identified. Three types of infant day care models were proposed: (1) the satellite model, a system which links the day care home providers with a day care center or community resource facility; (2) the home model, a system which delivers direct services through use of a home visitor as main link to outside resources; and (3) the center model. All three types of models (described in detail) emphasized inservice training as an integral program component, active encouragement of caregiver-parent communication, and full utilization of community resources. Recommendations, details of survey instruments, elaboration of findings, model-component charts, implementation plans and model budgets are included. (BF)
