ZERO TO THREE is a national nonprofit organization that informs, trains and supports professionals, policymakers and parents in their efforts to improve the lives of infants and toddlers. Neuroscientists have documented that our earliest days, weeks and months of life are a period of unparalleled growth when trillions of brain cell connections are made. Research and clinical experience also demonstrate that health and development are directly influenced by the quality of care and experiences a child has with his parents and other adults. That is why at ZERO TO THREE our mission is to ensure all babies and toddlers have a strong start in life. We know that as babies, the way we are held, talked to and cared for teaches us about who we are and how we are valued. This profoundly shapes who we will become. Early experiences set a course for a lifelong process of discovery about ourselves and the world around us. Simply put, early experiences matter. We encourage you to learn more about very young children, early development and the work of ZERO TO THREE by exploring our site. Explore opportunities at zerotothree.org/careers
