This article advocates for system-level change in prenatal health services. Specifically, the authors describe how they "discovered" the idea of father-inclusive prenatal health care (FIPH), which involves providing an array of services to help young expectant fathers prepare for the challenges of parenthood. Over the course of 25 years, research with young parents led to a series of "aha moments," inspiring the authors to advocate for the transformation of prenatal care to include services for fathers, guided by a well-defined, strategic approach. They include lessons learned from their work with young fathers, including two young men--Darnel and Victor--whose personal journeys informed the development of these ideas and convictions. Prenatal care is an often underutilized opportunity for helping young parents provide their children with a stable family life at a time when family stability is a vital public health challenge.
