Healthy Start is marking its 30th year of helping mothers and babies across Florida. The program, launched by Governor Lawton Chiles, provides health screenings to pregnant women and then to their newborns and connects them to other services they may need. Its work has helped to cut Florida’s infant mortality rate by 32 percent. Representatives gathered last week at the Wellington-area campus of HomeSafe, a nonprofit that helps abused children, to acknowledge the program’s success, but said they have plenty of more work to do, led by lowering the infant mortality rate for Black babies.
