How Old Is Brittany Cartwright's Son? Age in 2026

The Short Answer: Brittany Cartwright's Son Is 5

Cruz Michael Cauchi, the son of Brittany Cartwright and her ex-husband Jax Taylor, is 5 years old as of October 2026. He was born on April 12, 2021, at 1:51 p.m., and his parents announced his arrival on Instagram the following day.

Cruz celebrated his fifth birthday on April 12, 2026, with both parents posting separate heartfelt tributes. He is Brittany's first and only child. Fans first met Brittany on Vanderpump Rules, where she appeared from 2015 to 2020, and have followed her return to Bravo on The Valley, which premiered in 2024 and aired its third season in 2026.

The name Cruz means "cross" in Spanish, a choice Brittany has said resonated with her religious upbringing. His middle name, Michael, and surname Cauchi honor family: Cauchi is Jax Taylor's legal surname (his birth name is Jason Cauchi), a tribute to his late father.

Brittany Cartwright's Kids: Names, Ages, and Birth Dates

Brittany Cartwright has one child: her son Cruz. Here is the at-a-glance breakdown.

Cruz arrived a little over a year after his parents married in a lavish Kentucky castle ceremony in June 2019. Brittany announced the pregnancy in September 2020, when she was 11 weeks along, and the couple revealed they were having a boy shortly after. When Cruz was born in April 2021, Brittany wrote on Instagram that her life had changed forever in the best way possible and called him a dream come true.

Jax has honored his son in permanent ink: in November 2024 he revealed a new tattoo on the side of his neck showing Cruz's birth date, April 12, 2021, topped with the Aries ram symbol for Cruz's zodiac sign.

As of October 2026, Brittany has not announced plans for a second child, though she has said in 2026 interviews that she remains open to the possibility of having more children in the future.

Cruz's Birth Story: April 2021

Cruz Michael Cauchi was born on April 12, 2021, in Los Angeles. Brittany shared the news on Instagram on April 13 with a family photo, writing: "Yesterday, April 12th at 1:51pm, our lives changed forever in the absolute best way possible. Our beautiful son Cruz Michael Cauchi was born and we have never been more in love."

Choosing the name took time. Brittany told E! News that she and Jax had a girl's name picked out from the very beginning, so when they learned they were having a boy, the decision took a while. She was about five months pregnant when they finally settled on Cruz, a name she found both meaningful and cute, and one she felt went perfectly with Cauchi.

Cruz was part of the Vanderpump Rules baby boom of 2021: Stassi Schroeder's daughter Hartford arrived in January, Lala Kent's daughter Ocean in March, and Cruz in April, followed by Scheana Shay's daughter Summer Moon later that month. The babies' overlapping arrivals became a defining storyline for the show's extended universe.

From birth, Cruz has lived much of his life in front of cameras, first through his parents' social media and later on The Valley, where viewers have watched him grow from a toddler into a 5-year-old kindergartner.

Co-Parenting and the 2026 Custody Agreement

Brittany and Jax announced their separation in early 2024, and Brittany filed for divorce in August 2024, listing January 24, 2024 as the date of separation. In March 2026, the former couple finalized a custody agreement for 5-year-old Cruz, as reported by Page Six and covered across entertainment media.

Under the agreement, the parents share joint legal and physical custody. Jax has parenting time every other weekend and on Wednesday evenings, while Brittany has Cruz for the rest of the week. Brittany holds final say on medical decisions if the two cannot agree. One of the most discussed provisions requires both parents to remain sober while caring for Cruz, with no alcohol, marijuana, or other drugs during custody time.

Brittany has been open about the ups and downs of co-parenting. Speaking to Bravo's The Daily Dish in April 2026, she called co-parenting "an uphill battle" but stressed that both parents put Cruz first and that he does not see the struggles. She also confirmed that Jax was sober, calling it a great achievement.

For his fifth birthday on April 12, 2026, both parents posted separate tributes. Jax, who stepped away from The Valley after season 2 to focus on his sobriety and mental health, shared a carousel of father-son moments and wrote that being Cruz's dad was the greatest gift he had ever received.

Kindergarten and Life at 5 in 2026

The biggest milestone of Cruz's fifth year came in the fall of 2026, when he started kindergarten. Brittany discussed the transition on her podcast, When Reality Hits, in August 2026, marveling that her baby was starting "actual kindergarten, no more pre-school," and adjusting to the new 8 a.m. to 2:32 p.m. school schedule.

She also shared that Cruz has an individualized education program (IEP) in progress and continues to see occupational and speech therapists after school and on weekends. In 2025, Brittany had publicly discussed Cruz's autism diagnosis, and her 2026 updates have emphasized how well he is doing: thriving, happy, and getting all the support he needs.

In July 2026, Brittany posted a "life lately" photo dump featuring 5-year-old Cruz prominently, from wedding weekends to arcade outings, describing herself as single, healing, and in a much better place emotionally. Friends from The Valley, including Kristen Doute and Scheana Shay, remain part of her circle, and their children frequently appear together.

As of October 2026, Cruz is settling into kindergarten life as a happy, supported 5-year-old, with both parents publicly committed to keeping him at the center of everything.

Jax Taylor's own journey has been closely tied to Cruz's fifth year. After stepping away from The Valley following season 2 to prioritize his sobriety and mental health, Jax returned to social media in 2026 with raw, emotional tributes to his son. For Cruz's fifth birthday on April 12, 2026, he shared a carousel of father-son moments, from pool days to aquarium outings, writing that being Cruz's dad was the greatest gift he had ever received and vowing to always protect and guide him. Brittany, for her part, told Bravo's The Daily Dish in April 2026 that she was very happy Jax was sober, calling it a great achievement even as she acknowledged co-parenting remains an uphill battle. The March 2026 custody agreement formalized their arrangement: joint legal and physical custody, with Jax seeing Cruz every other weekend and Wednesday evenings. Through the changes, both parents have said the same thing in 2026 interviews: Cruz, now 5 and thriving in kindergarten, comes first.
