Rory Culkin Reveals the Blunt Parenting Advice He Received From Brothers Macaulay and Kieran After Welcoming Baby Havoc

Rory Culkin has stepped into fatherhood, welcoming his daughter, Havoc Moon, with partner and cinematographer Kate Arizmendi. While navigating the early months of parenting, the 37-year-old actor received straightforward, no-nonsense reassurance from his famous older brothers, Macaulay and Kieran Culkin: stop overthinking, because everyone figures it out eventually.

Speaking at the New York City premiere for his psychological thriller series Nocturne, Culkin admitted that while new fatherhood brings real challenges, the emotional shift has completely rewired how he experiences daily life.

The transition to caring for an infant introduced a surprising emotional weight that catches him off guard during routine moments around New York City.

How Fatherhood Shifted Rory Culkin’s Everyday Reality

Since welcoming baby Havoc in May, Culkin noted that ordinary routines carry an entirely different resonance. Leaving home for work or travel is no longer a simple commute.

“Certain movies will hit harder now. Having a child introduces you to time, and now everything just feels a little heavier. I mean, when I have to say goodbye to her, I get choked up on the train … there’s just more gravity now, you know?”

Despite warnings from friends and peers about the grueling sleep deprivation and stress that accompany a newborn, Culkin shared that the emotional return makes the exhaustion secondary.

“Fatherhood has been lovely. Really such a pleasure,” he shared. “I mean, everyone was telling me how difficult it is — and it is — but that’s outweighed so much by the love.”

The Culkin Family Playbook: Simple Advice From Seasoned Dads

With older brothers Macaulay Culkin, 46, and Kieran Culkin, 44, already raising children of their own, Rory turned to his siblings for perspective before the arrival of his daughter.

Rather than offering strict schedules or parenting manuals, both veteran actors kept their guidance remarkably simple.

“Their advice was ‘You’ll figure it out. Everyone does … So, you know, just don’t worry.’”

Busting the Myth of the Perfect Parent Blueprint

A common misconception among first-time parents is that success requires meticulous preparation and exhaustive rulebooks before the baby arrives. Experienced parents often note that hands-on instinct and daily adaptation matter far more than rigid theory, a sentiment echoed directly by the Culkin family’s guidance.

That grounded philosophy extended to early family holidays as well. Rather than planning elaborate festivities for baby Havoc’s first Halloween in New York City, Culkin kept expectations modest, opting for a quick costume photo session at home before an early bedtime.

Balancing New Fatherhood With Apple TV’s ‘Nocturne’

Alongside his new home life, Culkin is starring in the Apple TV psychological thriller Nocturne, appearing opposite Liev Schreiber, Zazie Beetz, and Stephen Graham.

Culkin forged a particularly tight connection with co-star Graham off camera. The two spent time visiting local theaters and museums together to develop deep mutual trust before filming intense scenes.

“Rehearsals were great, but [our] discussions [outside of set] I feel like goes further,” Culkin said. “Because then you just build trust — you learn about each other. And the friendlier you are with an actor, the harder you can go onscreen.”

That chemistry is currently on display on Apple TV, where Nocturne drops weekly episodes on Fridays leading through Dec. 25.
