More than 5,000 babies born in Indiana in February will be decked out in reds hats courtesy of the American Heart Association\u2019s \u201cLittle Hats, Big Hearts\u201d program. American Heart Association staff will deliver the tiny hats to 44 hospitals across the state beginning this week. The hats were lovingly hand-knitted by volunteers. February is American Heart Month, and the week of\u00a0Feb. 7-14\u00a0is Congenital Heart Defect Awareness Week. Heart disease remains the No. 1 cause of death in the United States and in Indiana, and congenital heart defects are the leading birth defect in newborns. The Little Hats, Big Hearts program raises awareness about both. Volunteers interested in donating materials or knitting hats for next year, or hospitals that would like to participate in the program, should call the American Heart Association at\u00a0(317) 732-4700.
