In November 2024, Josh told PEOPLE that though he was “tougher with my older kids,” his younger daughters have been testing him.

“My girls are strong personalities and they’re testing it, and I know the test,” he said. “Kids look up to you like a god, and they think if they can break you then they’re not safe.”

Trevor Mansur Brolin was born on June 26, 1988, to Josh and his first wife, Alice. At the time, Josh was only 20 while Alice was 22.

“I was getting ready to have my first kid. And everyone told me I shouldn’t,” he toldThe Guardian.“I was an idiot. A 19-year-old guy riding on a Harley-Davidson, so embarrassingly dumb. But she got pregnant and that’s what happened.”

He continued, “That was a good year. That was my favorite year. It was the year my whole life changed. I had kids and I started doing theatre.”

Despite coming from a well-established acting family — his grandfather isJames Brolin– Trevor decided not to go into the field. However, he did stay in the entertainment industry with his job atRevel, a venue offering everything from live music to game nights in Albuquerque, New Mexico.

In June 2022, Josh posted a sweet birthday shout-out for his son onInstagram. “Trevor, my first born. I cannot express the depths of my respect for you,” he wrote next to a photo of his only son as a child. “I don’t know anybody like you and I love it that way. You’ve never seen things in a way that hasn’t moved or awed me, and to be your dad, man, is the greatest lottery I could ever win. I love you so much. Happy Birthday.”

Josh and Alice welcomed their second child together, daughter Eden Brolin, on Nov. 30, 1994. The couple went on to divorce that same year but remained close friends and co-parents.

Speaking to Fatherly,the actor explained how he managed a burgeoning Hollywood career with fatherhood. “When I had my older kids, when they were young, I was really into it. I was always into being a dad. But I was always worried about not working,” he said. “The day after Eden was born, I was on a plane for New York to do a pilot. It was horrible.”

Next to a photo of him and Eden on the way to the ceremony, he shared a lengthy and heartfelt post. “My daughter last night, my God, and her groom: awe,” he wrote. “I am so grateful for this time and this place to be able to have this time on. There are the kindest people out there. I have little kids to raise again, entire lives to monitor and be sensitive to.”

Continuing, he reflected on being able to give her away on her big day. “I stayed and walked my daughter over a grassy countryside to a commitment — a groom with tears falling down his cheeks — and I melted with it, into it," he added.

Two years after Josh and his wife, Kathryn, said “I do,” the pair welcomed their first child together. Westlyn Reign Brolin was born on Nov. 3, 2018.

Josh announced the news with anInstagram videoof his daughter. “I would like to introduce our little girl Westlyn Reign Brolin (Bean). Mama Kathryn was stellar during this miracle birth and Bean is a flawless gem through and through,” he wrote, adding, “We are blessed to the core."

After her birth, Josh took an extended paternity leave to spend time with the newborn. “He dropped everything,” his father James told PEOPLE in April 2019, adding that Josh was doing “nothing but diapering for three months.”

Since then, Josh has continued to showcase his hands-on approach to parenting. The actor even went as far as sitting on a tiny pink toilet tohelp potty train his daughterin May 2021. He shared the hilarious moment in anInstagramphoto of himself crouched on the small toilet while Westlyn stood next to him, writing, “There’s nothing like the power of example.”

Over a year later, theDunestar marked his daughter’s 4th birthday with a photo of histwo little girls on Instagram. “Happy 4th to our Lil Bean," he wrote. “You move mountains in us, girlie; cultivate utterly majestic worlds with your imagination; and make us so simply giggle when we least expect it. Papa Bear loves you crazy train.”

Now 6, Westlyn is already showing signs of interest in the entertainment industry. In May 2023, Josh shared a sweet series of photos ofher first dance recitalon his Instagram Story. “So proud of my little girl on her first dance recital 🎉🎉💎💎❤️,” he wrote across one photo, showing Westlyn wearing a sparkly, purple leotard and smiling for the camera.

A couple of days after her birth, Josh shared the special meaning behind her nameon Instagram. “Everywhere we have traveled the one place Kathryn and I always found a great solace in were chapels,” he wrote.

“Not being particularly religious, but a God feeling heavily inundating our lives, chapels have always been the sanctuaries where we felt most connectedly free to give thanks," he continued. “Chapel Grace is, to us, a manifestation of that celestial feeling that was always felt as we meandered and knelt.”

Shortly before her first birthday, Josh shared a sweet black-and-white photo of him and Chapel onInstagramwith the caption, “My littlest, my diamond heart. Your smiles are feral and your chuckle is toddler eruptive.” He continued with a lengthy tribute to his youngest child, calling her “a membrane of unadulterated joy.”

When Chapel was 2 years old, she, her mom and her big sister Westlynjoined Josh on location as he filmedDune: Part 2.

“We climbed the dunes every day. It was awesome,” he said during an appearance onGood Morning Americain February 2024. “When you first end up in the desert, you feel so insignificant because we were 2 and a half hours south of Abu Dhabi. So it was a hundred kilometers of nothing but sand.”
