Works with families to get them enrolled in the 1st Five Healthy Mental Development Initiative. 1st Five program builds partnerships between physician practices and public service providers to enhance high-quality well-child care. 1st Five promotes the use of developmental tools that support healthy mental development for young children during the first five years. By using a tool for all children that includes social-emotional development and family risk factors, providers are able to identify children at risk for developmental concerns that, if left untreated, would play out later in life.
