Grounded in the experience of First 5s, the First 5 Center for Children’s Policy studies and disseminates best practices and solutions in early childhood development; convenes experts inside and outside the early childhood space to inform policy; and evaluates solutions within and outside California that can be adapted for the state. The CDN is partnering with the Center to generate policy-relevant information about the physical health of infants and their mothers, mental health of young children, and availability of health care providers across the state of California.
