The 35-year-old actor and his 34-year-old wife stepped out with their 1-month-old bundle of joy earlier this week while making their way through L.A.'s LAX airport.
Little Justice was dressed adorably in a light pink onesie. Her mama flashed a smile for the photogs while holding Justice tight as the family went through security.
The couple announced the arrival of their first child last month via Twitter, writing, "We are happy to announce the birth of our precious baby girl, Justice Jay 'JJ' Ackles. She was born happy and healthy on May 30th."
"It's been quite the adjustment," Ackles told E! News exclusively earlier this week when asked about balancing fatherhood and filming the new season of his show Supernatural. "A friend of mine says it's a slightly different gear, and I said, different gear? No, you put it in park, you get out of the car, you get in a different car, you take a left down a wrong street; that's basically where I'm at now."
He continued, "I'm lost, I'm just completely lost. Season nine started and I got back to work where I at least had some sort of understanding of what's happening around me, but the baby's doing great and for me I think it's just going to be a lot more travel."
