March for Babies is the March of Dimes biggest fundraiser and America's favorite walking event. The money raised supports the March of Dimes mission to improve the health of babies. We are fighting premature birth! It's the #1 killer of babies and it costs American businesses billions of dollars annually. March for Babies helps families win the fight against premature birth. It funds treatments that help more women go full term and have healthy babies. It funds research to discover the unknown causes of premature birth and find new ways to stop it. We invite you to join our cause and be part of an inspiring community of families and businesses fighting for every baby.
