About 400 children and 10,000 adults are waiting for liver transplants nationwide, said Amy Feldman, medical director of the liver transplant program at Children’s Hospital Colorado. On average, about 10% of babies and 5% of older children die before receiving a liver, she said. “For children, it’s especially difficult to find organs because they’re small,” Feldman said. “If we had enough organs, we could save all these kids.”
