Milo Ventimiglia And Jarah Mariano Celebrate New Arrival!

A Sweet Addition to the Family

Milo Ventimiglia and Jarah Mariano have expanded their family with the arrival of their second child, a baby boy named Rock-Anthony Makoa Ventimiglia. This exciting news means that the "This Is Us" star and his model wife are now proud parents of a family of five, which also includes their adorable 18-month-old daughter, Ke'ala Coral, and their beloved dog, Duke.

Mariano took to Instagram to share the joyous announcement, posting intimate black-and-white photos of their growing family. "These last couple of weeks have been chaos, but in the best possible way," she wrote. "Welcome back home, Rock-Anthony Makoa Ventimiglia. Can't wait for all of the adventures ahead with our family of 5!"

Milo's Dream of a Sibling for Ke'ala

Before Rock-Anthony's arrival, Ventimiglia expressed his excitement about becoming a father of two, especially eager to see how Ke'ala would embrace her new role as a big sister. "I'm most excited for my daughter to have a sibling, someone to grow up with," he shared with People, highlighting the joy of expanding their family.

The couple had announced Mariano's second pregnancy earlier in January, during a celebration of Ke'ala's first birthday. Mariano's heartfelt Instagram tribute revealed not only her growing baby bump but also her reflections on how profoundly motherhood has transformed her life.

Honoring Hawaiian Heritage

The names of Ventimiglia and Mariano's children hold special significance, drawing inspiration from Hawaiian culture as a nod to Mariano's roots. Born on the island of Kauai, Mariano has passed down her heritage through her children's names. Their daughter's name, Ke'ala Coral, means "the pathway" or "the fragrance," while their son's middle name, Makoa, translates to "fearless," continuing a meaningful family tradition.

Motherhood Over 40: A Growing Trend

At 42, Mariano joins a growing trend of mothers having children later in life. According to a 2025 report from the National Center for Health Statistics, births among women aged 40 and older have reached a historic milestone, surpassing teen births for the first time.

Between 1990 and 2023, fertility rates for women aged 40 to 44 increased by 127%, and by 450% for those aged 45 and older. Experts point to advancements in fertility treatments and prenatal care, as well as financial stability and career prioritization, as contributing factors.

Mariano welcomed her daughter Ke'ala at 41 and now her son Rock-Anthony at 42, embodying a path that resonates with many women today.

A New Chapter for the Ventimiglia Family

The arrival of Rock-Anthony signals a new and joyful chapter for Ventimiglia and Mariano. Their journey has been marked by both happiness and challenges, including the loss of their Malibu home in the California wildfires shortly after Ke'ala's birth.

With Ke'ala now stepping into her role as a big sister and baby Rock-Anthony nestled at home, the Ventimiglia family has much to celebrate as they look forward to new adventures together.
