Requires the Department of Health and Human Services to run a national public-awareness campaign and to issue guidance to States to promote fathers’ inclusion and engagement before, during, and after birth. The campaign and guidance focus on practical actions—attendance at prenatal visits, support for breastfeeding, father-to-infant skin-to-skin contact, screening for paternal postpartum depression, and recognizing pregnancy complications—and set timelines for rollout and evaluation. The Comptroller General must study and report on the law’s effectiveness within six years.
