First-time parenthood is scary for everyone, but it was especially terrifying for Chris Pratt and Anna Faris, whose now-2-year-old son Jack was born nine weeks premature back in 2012. During Pratt's recent GQ Man of the Year interview, the couple revealed new details about their little boy's worrisome first days in the hospital.

"He was born at three pounds," Faris, 37, shared with the mag, "and we were told, 'Okay, you need to be prepared for raising a special-needs child.' And we felt like it was devastating, but it also felt like, you know, 'We can do this.'"

"He's alive," Pratt, 35, added.

Indeed, the Guardians of the Galaxy hunk told David Letterman in 2013 that Jack is a "totally healthy" kid. "He is just so perfect and I love him so much," the proud dad gushed.

More recently, Pratt told Us Weekly that his son is starting to develop a personality, and likes and dislikes. "He's saying his sentences. He's actually having conversations now," the Parks and Recreation star said in July. "He loves monster trucks and everything construction."

Of how his life had changed since becoming a father, he added, "The truth is, up until having a kid, each career was essentially our main priority...Our careers are still very high on the list, but our son is the main priority."
