In their joint statement, Pratt and Faris made sure to include Jack, writing, "Our son has two parents who love him very much and for his sake we want to keep this situation as private as possible moving forward."
"He was born at three pounds," Faris told GQ in November 2014. "And we were told, 'OK, you need to be prepared for raising a special-needs child.'"
The parents admitted the news was "devastating" when they first learned of the challenges ahead, but they knew they could face them head-on.
"It also felt like, you know, 'We can do this,'" Faris said of the two being a team.
Pratt and Faris took their son home after a month in the NICU and so far, he's happy and healthy.
In December 2014, Pratt spoke at the March of Dimes Celebration of Babies, where he gave an emotional speech about his own son's early struggles, sharing, "Our Jack went from a small, helpless little squirt to a strong, smart, happy, funny, beautiful boy who loves monster trucks and Daniel Tiger, and, believe it or not, loves vegetables."
"I think that being a father is very meaningful and rewarding to Chris," Faris told Redbook magazine. "He's a great dad. He’s a little more serious than he was before. It forces your hand. You really have to become an adult."
"From what I understand, most of the terrible two stuff is the toddler's inability to express what they want. They know what they want, but they can't tell you because they don't know the words yet," Pratt explained. "He's so vocal that It's not that hard for him. It'’s super frustrating because you're like, 'Jack, I think it's time for you to go to bed,' and he's like, 'I thought about it and no thanks, Dad. Not right now.' He's so polite. What am I supposed to do?"
In March 2015, Faris also gushed about her only child.
"Jack's doing so well," she told Health. "I think that's why we can talk about it now a little bit. He's just so happy, bright and funny. For a while I thought maybe I'd be a stay-at-home mom for a couple of years."
She also clearly savored the time spent with Pratt and her child together.
"Yesterday Chris and I took Jack to the train museum," she shared. "There were paparazzi, but we were just like, 'It's an odd thing that's happening, but let's not stress or stress Jack out.' At one point, Chris turned to me and said, 'I don't think I've ever been happier in my whole life.' And I felt the same way."
"These press tours can be such a whirlwind. I'm grateful to have you and the boy with me on this one," he wrote alongside a picture of him and Faris posing on the red carpet. "Although it's 3 a.m. right now, I was just awakened by a square kick to the back as little man climbed into bed and then must have had a karate dream or something and now I can't sleep. I'm on Insta instead. All you dads and moms know what I'm talking about."
“That has been the best part of this world tour by far,” Pratt also told ET about having his family there to keep him company at the film’s press junket. “It’s nice to have your family with you because it brings you down to earth and when you leave your feet on the ground, you [realize] what it feels like to have your head in the clouds.”
“You go with the flow and things come and go and you’re not even there to record or observe them,” Pratt continued, explaining how life can become a whirlwind when he’s on his own. “So when [your family] bring you back down to earth you get to experience this -- or at least I do -- in a whole different way. When they are present with me, I get to be present with me as well.”
