Welcome Baby is a free and voluntary home visiting program established in fourteen communities throughout Los Angeles County. This locally designed home visiting program focuses on education and support for pregnant women and mothers of newborns. The model was piloted in one downtown Los Angeles community starting in 2009—designated Metro LA—offering services to women who give birth at California Hospital Medical Center (CHMC) and live within a five-mile radius of the hospital. Women were recruited into the program either prenatally or in the hospital after giving birth. Results from analysis of the 24-Month Child and Family Survey are mixed. Findings demonstrate that Welcome Baby has positive and significant impacts on a number of important domains, particularly with regard to positive parenting and child development, but no measurable effects on domains such as health coverage and maternal mental health.
