John also knew his wife would be a “good mother,” telling PEOPLE in 2023, “This is a lot for me to say.She is as good as my mother was. I mean, when I watch her, the patience, the kindness she has for him, it’s so beautiful.”

In December 2024, Caitlin told PEOPLE that she and John tend to “balance” each other out when it comes to their parenting, adding, “I would say thatmy husband is a little easieron him than I am.”

John and Caitlin are teaching their son to give back. In October 2022, the actor spoke toE! Newsabout laying “the foundation of being loving and kind” for Billy.

“I think we’re pretty good examples, my wife and I,” John said. “The hard thing is he lives a pretty privileged life. [My wife’s] great, she takes him down to feed the homeless in Orange County and we take him on stuff like that. We try to show him it’s about service and giving back.”

A few months earlier, Caitlin shared photos from her and Billy’s visit with families of an Illumination Foundation house. The mother-son duo brought them dinner, gifts and activities. “It’s important to me to not just give listeners of the podcast action to take, but to walk the walk myself,” Caitlin penned onInstagram. “I’m also able to see the direct impact @ifhomeless has and can feel more comfortable asking you to support them too. I also love being able to share all this with my son.”
