Jimmy also spoke about how it was very spontaneous of him to address his viewers last spring on Jimmy Kimmel Live!. But I don't want to abuse my position.
He added, "I don't know if that's right or wrong or common or uncommon".
In an interview on "O, The Oprah Magazine", Kimmel said he and his wife "didn't want to get too close" to Billy because the child's future was unclear.
Kimmel's son was born with a heart defect and has already undergone two open-heart surgeries, including one three days after his April 21 birth.
"He'll have another surgery when he's around 6 or 7 years old", Kimmel told Winfrey, "but in the meantime, he's doing great".
Kimmel told Winfrey that he has no regrets about getting personal during his monologue.
"I don't know if it was scary, but it was uncomfortable, and it's not something I looked forward to", he admits. "I definitely felt a sense of relief when it was over", Kimmel said. "According to polls I've seen, it has cost me commercially", he said. "But when I told her I was feeling that way, she said, 'Oh, I'm so happy you said that because I was feeling that way too, and I didn't want to express it'".
There were several instances when Kimmel urged his viewers to call their representatives to pressure them on things like health care and gun control and once attempted to sway Trump supporters on immigration. "Ninety percent of the time, I'll joke around, but some of the jokes, I hope, make people think".
