This article describes some of the extraordinary accomplishments of the second cohort of states to participate in the Infant and Early Childhood Mental Health Financing Policy Project (IECMH-FPP). The purpose of the IECMHFPP is to support states' advancement of IECMH assessment, diagnosis, and treatment policies that will contribute to the healthy development of young children. The policy stories are meant to inspire and offer lessons learned for other states interested in advancing IECMH policy. And they demonstrate that state leaders working across early childhood systems can drive meaningful change. [For the first part, see EJ1244138.]
