In a recent interview to The Hollywood Reporter, Kimmel, however, said the little one is "doing great."
"Young Billy made his first visit to our office today. He's juggling. He's translating Flaubert from French into English. No - he smiles. That's pretty much it. He is very interested in ceiling fans. He likes those a lot. I could get him to pay the same amount for Netflix just to watch ceiling fans," Kimmel joked
Kimmel said he and McNearney "didn't know anything about heart surgery" before their son's birth and subsequent operation, and that the associated memories from the beginning of Billy's life were stressful and difficult, to say the least.
"I felt like I was in an episode of a television show where something terrible was happening. There were a lot of people scrambling around. At that point, I knew there was nothing I could do. They were all very good about keeping me abreast of what was happening, but I wanted them to just focus on him and not worry about me," he said.
