This book examines the role of various nutritional and other health problems on child development and provides an excellent overview of results of early childhood supplementation and stimulation programs. Echoing one of the workshop's undercurrents, the chapters in this book emphasize the importance of approaching child development in an integrated way that considers how its building blocks-health, nutrition, and psychosocial stimulation-interact with one another. For if we are to truly help these children who lag behind, our interventions must embrace not only their physical health, but also their functional well-being. PAHO is proud to issue this joint publication with TMRU and the World Bank.
