Early Childhood Development Initiative
Support for the prenatal-to-three (PN-3) period
Counties play a significant role in shaping early childhood systems, investing in essential services for infants and toddlers that contribute to strong communities and improved outcomes into adulthood. Across the United States, every county helps fund and manage efforts to strengthen families with young children. In fact, counties regularly deliver a wide range of programs and services to approximately 16 million children from birth to age three, addressing the needs of both young children and their families by overseeing and coordinating prenatal to age three (PN-3) services, including:
- Childcare
- Health and prenatal care
- Early intervention
- Home visiting
- Maternal health screenings
- Parent classes
- Early literacy programs
The National Association of Counties, through its Research Foundation, partners with the National Collaborative for Infants and Toddlers on the Counties for Kids (C4K) campaign.
