Samuel Hanke is a pediatric cardiologist in Cincinnati, but when you ask him for his title, he follows it by saying: "Most importantly, I'm Charlie's dad."
Hanke remembers the night 13 years ago when Charlie, then 3 weeks old, was fussier than usual, so he picked him up to soothe him back to sleep. With Charlie still in his arms, he sat on the couch, turned on the TV, and nodded off.
