The MIECHV program represents a smart federal investment that is providing an important impetus for states and localities to build strong systems for young children. Examples from all corners of the country illustrate how state administrators are using the MIECHV program to enhance alignment and coordination across health care, early childhood, and early intervention. When these early childhood systems are coordinated, duplication of services is minimized, and appropriately targeted services are maximized, strengthening the life trajectory for many young children. Strong systems make sense for supporting the healthy development of America's children and for ensuring that public dollars realize their full potential. (author abstract)
