Chandler Cameron weighed less than 4 pounds when she was born. She stayed in the hospital for about six weeks and has had two brain surgeries.“But she’s tough as nails, and luckily overcame everything,” said her mother, Laurie. “We’ve been very lucky.”Now 20, Cameron led her tie-dye clad team Saturday to help ensure other babies get the same odds she had.“I want to help babies that are born prematurely and make sure they live long, healthy lives like me,” she said.Cameron was one of more than 250 walkers in Saturday’s Forsyth County March for Babies.Organized by the March of Dimes, the annual event at Otwell Middle School surpassed its $117,880 goal by nearly $3,000, said Wendy Wyatt, community director for the north Georgia chapter.
