Welcome Baby is a free and voluntary home visiting program that provides education and support for pregnant women and mothers of newborns. The program was piloted in one downtown Los Angeles Community for five years, and recently expanded to thirteen communities across Los Angeles County. This report presents findings from the Urban Institute’s study of the early implementation of this expansion of Welcome Baby, and finds that, though the program was implemented unevenly across sites, it has generally succeeded across a range of hospital- and community-based settings, and providers praised the Welcome Baby model and were encouraged by the potential to positively impact the lives of families and young children.
