Babies born early or at low birth weights (less than 5.5 pounds) often face a lifetime of mental or physical challenges. The Babies Born Healthy network, organized by the United Way, includes a range of projects and partners such as the March of Dimes and the Department of Public Health. One of its efforts is the Strong Start Initiative, launched this spring by Grady Health System and the United Way to help at-risk expectant mothers. Grady, along with New Millennium Obstetrics and Gynecology and Providence Women’s Healthcare, runs a program called Centering Pregnancy that provides prenatal programs in a group setting. In a pilot, 97 percent of participating moms delivered normal-weight babies.
