This booklet reviews the developmental tasks and needs of infants and toddlers, describes the support for healthy development currently available in the United States, and documents needs which are not being met. Two major initiatives are proposed and strategies for their implementation are recommended. Proposals argue for the (1) establishment of a basic floor of integrated services for all infants and toddlers and their families and (2) expansion of comprehensive, integrated services for infants and toddlers with special health and developmental problems or disabling conditions and for their families. Key elements of the first initiative include preventive health care, a level of economic viability for families with infants and toddlers to allow for basic health and development, social support services for families of infants and toddlers, and high quality daily care for newborns and for infants and toddlers. Key elements of the second initiative include provision of basic survival needs, health care for vulnerable infants and toddlers, psychosocial support and intervention for highly stressed families, adequate therapeutic and respite care for high-risk or disabled infants and toddlers, and integrated service system approaches to families of infants and toddlers with special needs.
