He’s just a few days into fatherhood, but John Stamos is loving every second of it! The emotional dad and his wife, Caitlin McHugh, welcomed their baby boy Billy earlier this week, and the actor is already gushing about his new addition. “It’s so beautiful having a baby. You have to do it, Ryan!” he revealed to Ryan Seacrest on Thursday, April 19.

He further explained the inspiration behind little Billy’s moniker while calling into Ryan’s talk show On Air With Ryan Seacrest, stating that he was named after John’s father, “who was my hero. I hope I live up to what my dad did.” The Fuller House star’s father passed away in 1998, and his legacy is now living on in his grandson. “He was always bigger than life to me so I’m happy to honor him with our little Billy,” he continued while getting a little teary-eyed. “I’m starting to cry right now, Ryan! I am so emotional!”

The 54-year-old actor has always been open about wanting children, but he’s so happy now that it’s finally happened. “No, you know, people are probably sick of me saying I always wanted a kid but it just happened and I guess I was waiting for the perfect wife, which I have,” he added during the interview. “Caitlin, she’s been so graceful through this whole thing. [Her delivery] was about 20 minutes. A little baby came out and he looked just like Don Rickles,” he joked.

Back on Monday, April 16, John took to Instagram to share the first photo of Billy, in which the baby can be seen resting his head on John’s chest. “From now on, the best part of me will always be my wife and my son. Welcome Billy Stamos (named after my father) #NotJustanUncleAnymore #Overjoyed,” he captioned the sweet snap of his bundle of joy. He did not specify the baby’s exact birthdate in the post.

In a previous interview, the actor noted how his late father and mother would have loved his wife, Caitlin. “I know my parents are smiling down,” he told Entertainment Tonight. “I know they would love her. She’s a gentle, kind, graceful soul who would be a good mother.”

John and Caitlin previously announced they were expecting in December 2017 and then married in early February 2018. “We just kind of crammed everything in because it’s been so great,” he added during his interview with Ryan. He previously gushed to People about being “a fun dad” once their baby was born. “I’ve been practicing for a long time. I’ve done every schtick you can do with a baby on TV… all the bits and jokes and diaper gags. I’ll probably just do all that stuff,” he said.

Earlier this month, he assitionally sang his praises for Caitlin. “My whole life I’ve waited for this moment and the best part is I’m getting to parent with the most perfect woman. She’s just humble and sweet,” he said. “I have to watch her because it takes her 30 seconds to win somebody over. She’s a really special person.”

So, are more babies in the future for John and Caitlin? “She’s already talking about baby No. 2,” John revealed in a recent interview with Life & Style. “We just finished decorating the house… [and] she’s already on the internet looking at new homes that are bigger!” Congrats again to the couple on their new addition, baby Billy!
