Isaac Hinkel is a 2-year-old boy with a contagious smile and a rare birth defect. His parents, Jill and Dan, learned before he was born that something was wrong with his development. They searched for the right care and found confidence in surgeons at Cincinnati Children's Hospital Medical Center, where doctors diagnosed Isaac with a rare birth defect called OEIS (omphalocele-exstrophy-imperforate-anus-­spinal). He would need a series of surgeries to repair his abdomen and spine. Isaac is paralyzed from the waist down and uses a toddler-sized custom wheelchair to get around. His struggles haven't dampened his spirit. "It's his world," his dad, Dan, says, "and he lets us join him in it."
