Memphis Lafferty nearly died from a meningitis infection when he was just 6 months old. Though he survived the disease, he had to have all four of his limbs amputated. Now he's a talented 12-year-old who builds intricate miniature skateboards, using his mouth to hold the tools. Chris Lafferty says his son never lets that challenge get in his way. "His confidence is so big and strong," he said.
