The National Institute of Child Health and Human Development (NICHD)
The mission of the NICHD is to ensure that every person is born healthy and wanted, that women suffer no harmful effects from reproductive processes, and that all children have the chance to achieve their full potential for healthy and productive lives, free from disease or disability, and to ensure the health, productivity, independence, and well-being of all people through optimal rehabilitation. The NICHD Information Resource Center is your one-stop source for NICHD brochures, booklets, and other materials related to the health of children, adults, families, and populations.
