John Mulaney has got his kid following in his footsteps.

While speaking with People at the opening of his new Broadway show, ALL IN: Comedy About Love, in New York City on Monday, Dec. 16, Mulaney, 42, shared how he’s balancing rehearsals with fatherhood.

The comedian is dad to son Malcolm, 3, and daughter Méi, 3 months, with his wife, Olivia Munn.

“My son’s been coming to a lot of rehearsals, so he’s heard The Bengsons and our amazing band warm up a lot and he really enjoys that,” Mulaney told People.

“He brought a ukulele yesterday.”

Mulaney proudly added, “He played along with the band. So he’s been here a lot. He loves the theater. He was standing on stage for a while and then said, ‘I love stage.’”

The comedian also previously opened up to the outlet in November at the GQ “Man of the Year” party about how Malcolm is adjusting to life as a big brother following Méi’s arrival on Sept. 14.

“He’s doing good. He likes it,” Mulaney shared. “It’s interesting, with our daughter, she’s two months old so she doesn’t do much.”

Mulaney continued with a laugh, “I think the first couple of weeks he thought she might be a toy because she’d squeak, and he’d be like, ‘How do I make it do that again?’ Now I think he gets it, that this is a little girl, yeah.”
