This newsletter issue is about the growth of programs that serve infants, toddlers, and their families, and the management of that growth. The articles address early intervention programs with infants and young children with disabilities. The first article, "Implementing a Multi-site, Multidisciplinary Clinical Trial: The Infant Health and Development Program" (by Ruth T. Gross and Christine Hayes), describes a program combining early child development and family support services with pediatric follow-up for reducing the developmental and health problems of low birthweight, premature infants. The second article, "Empowering Parents--the Evolution, Evaluation and Expansion of a Program", by Walter Barker, describes the rationale, problems, and success of the Child Development Program covering 30 health authorities in England, Northern Ireland, Wales, and the Irish Republic. "Healthy Growth for Hawaii's 'Healthy Start': Toward a Systematic Statewide Approach to the Prevention of Child Abuse and Neglect" by Gail Breakey and Betsy Pratt. It describes the critical elements of the Healthy Start program and examines the processes of collaboration and advocacy that have fostered program expansion. The fourth article is "Replicating Demonstration Projects: A Beginner's Guide" (by Marilyn M. Segal and Luba Lynch) which identifies critical features of a replicable model, describes the replication process, and notes the role of the process evaluation. The last article "Managing Growth at Child Care Solutions" by Ruth Anne Foote describes principles of growth which have helped one program cope with current demands and meet new demands. (DB)
