On September 27, 2023, ZERO TO THREE released the State of Babies Yearbook: 2023. This resource is a blueprint for transformation to put our nation on the path towards a comprehensive infant-toddler agenda. The Yearbook identifies five imperatives where urgent action is needed at the federal level: maternal health, infant and early childhood mental health (IECMH), child care, housing, and economic security. The Yearbook and its website (www.stateofbabies.org) are designed to bridge the gap between science and policy with national and state-by-state data on the well-being of babies and families in the United States.
