The late night talk show host dedicated a message to his son, his family and everyone involved in Billy’s surgery.

“This weekend our boy Billy underwent his third (of hopefully three) open heart surgery,” Kimmel shared on Instagram. “We approached this experience with a lot of optimism and almost as much fear and came away with a new valve inside a happy, healthy child.”

THE Jimmy Kimmel Live! The host praised the team at Children’s Hospital Los Angeles, where his son Billy was treated.

“Walking through this hospital, meeting parents in their most vulnerable state, children in pain, and miracle workers doing everything in their power to save them is a humbling experience,” Kimmel wrote. “We hope you never need CHLA, but if you do, know that it helps families regardless of their ability to pay, thanks in large part to the Affordable Care Act (another tribute to the late Senator John McCain), to generous donations from companies like Disney, for whom I am proud to work and especially from generous people like you.

The comedian also thanked the “loving strangers who took the time to pray and send positive energy to our baby,” and also had a few words for his family.

“Thanks to my wife Molly for being stronger than any mom is reasonable and Billy, you are the toughest (and funniest) 7 year old we know,” he said. -he adds. “There are so many parents and children who don’t have the chance to go home after five days.”
