"When Molly McNearney gave birth to their son William Billy Kimmel in April 2017, everything in those first hours seemed perfectly normal. But about three hours after Billy was born, a sharp-eyed nurse noticed that the newborn's color was turning purple and detected a heart murmur. Tests followed quickly, and the diagnosis that came back was one of the most frightening things any new parent could hear. Billy had been born with a rare congenital heart defect called Tetralogy of Fallot with pulmonary atresia, a condition in which there is a hole in the wall between the two sides of the heart and the pulmonary valve is completely blocked, meaning his blood was not carrying enough oxygen. At just three days old, Billy was taken to Children's Hospital Los Angeles for emergency open heart surgery. Those hours were the longest of Jimmy and Molly's lives. Billy came through. And then something happened that television will not soon forget. Jimmy returned to his show and delivered a thirteen-minute monologue, breaking down in tears in front of his entire audience, sharing every terrifying detail of what his family had just lived through. He said that no parent should ever have to wonder whether they can afford to save their child's life. Back at home, Molly was on maternity leave, sitting on the sofa breastfeeding Billy with her mother beside her, watching the broadcast. She told The Hollywood Reporter that she sobbed through the entire thing and could not believe the strength it took for Jimmy to stand up there and tell that story just one week after it had happened. She said he had fourteen writers ready to help him, but he walked into his own office, closed the door, and wrote every word himself. Billy went on to have a second surgery at seven months old and a third when he was seven years old, with Jimmy sharing the news publicly each time. In every one of those moments, Jimmy was not just a late night host. He was a father standing firm beside his family."
