For more than 30 years, March of Dimes has hosted the March for Babies.It's a fundraiser that helps collect money for programs aimed at helping moms have healthy full term pregnancies. It also helps fund medical research for sick babies. Last year, March of Dimes raised nearly $500,000. They hope to do that again this year to help support their cause.
