Brolin and his wife, entrepreneur Kathryn Boyd, welcomed their first child together in the fall, the actor announced on Instagram in early November.

“Dearest Ladies and Gentlemen, I would like to introduce our little girl Westlyn Reign Brolin (Bean),” he wrote of a video showing the newborn sound asleep. “Mama Kathryn was stellar during this miracle birth and Bean is a flawless gem through and through.”

“We are blessed to the core and appreciate so much the love and support during this pregnancy from ALL who have partaken in our journey, directly and/or indirectly,” he added.

The baby girl’s step-grandmother has been married to Brolin’s father, fellow actor James Brolin, since 1998 — and she couldn’t wait for little Westlyn’s arrival.

In June, Brolin joked that Streisand is a “typical Jewish grandmother,” telling PEOPLE and Entertainment Weekly’s Editorial Director Jess Cagle that his stepmother got emotional over a special gift Boyd gave her.

“My wife got her a bracelet that said ‘Grandma’ on it and she started crying,” the Sicario: Day of the Soldado actor said. “She is one of those … it’s annoying but in a really great way, [with] emails every day and like, ‘Hey, I thought of this name, what do you think of that? … When can I come over and feel the baby?’ “
