Josh Brolin is proving that he's a family man. On Friday, Brolin's wife Kathryn Boyd Brolin, 35, shared a carousel of rare photos on Instagram that featured the _Dune_ actor, 55,

and their two daughters. In the first photo, Brolin lifts his daughter Westlyn, 4, in the air while his other daughter Chapel, 2, balances in the bed of a truck. In another photo, Brolin

sits in the trunk with Westlyn in his lap while Chapel lies on her jacket next to them. In the third snap, Chapel holds her hands over her eyes as Brolin holds Westlyn in the background.

"Somewhere in New Mexico..." Kathryn captioned the post. _NEVER MISS A STORY — SIGN UP FOR PEOPLE'S FREE DAILY NEWSLETTER TO STAY UP-TO-DATE ON THE BEST OF WHAT PEOPLE HAS TO

with both of their grandfathers. Brolin's father, James Brolin, 82, carries Chapel while Kathryn's father, Britt Boyd, holds Westlyn. "Grandpa(s) love," Brolin captioned

the photo. While Brolin and his wife Kathryn are notoriously private about their kids, the pair shared their funny attempt at a family photo on Instagram in December. "Power naps and

power poses. ✨," Kathryn captioned the shot, which appeared to be from a trip the couple took in September celebrating their sixth wedding anniversary. Brolin and Kathryn tied the knot

in September 2016. The actor also has two adult children — daughter Eden, 29, and son Trevor, 34 — from his first marriage to actress Alice Adair. The wedding also led Brolin to reflect on

the experience of watching his older children build lives while still raising his young ones. "I am so grateful for this time and this place to be able to have this time on," he

wrote. "I have little kids to raise again, entire lives to monitor and be sensitive to."
