In the photos, Kristopher can be seen cradling the newborn in his arms, while other images show Kaitlynn holding the baby as the 34-year-old peers outside the hospital window.

Lots of stars sent the couple well-wishes in the comments section, including Anna Marie Tendler, who wrote, "Congratulations Kaitlynn!! (Also sushi in the hospital is an A+ move."
Linda Thompson, who is mother to Kaitlynn's ex Brody Jenner, commented, "Awwww!! Beautiful! Congratulations sweetheart!" while Bachelor Nation's Becca Tilley added, "I'm just so beyond happy for you! She's perfect! congratulations!"
Kaitlynn and Kristopher are also parents to 16-month-old son Rowan Carter Brock, who they welcomed in September 2021.

As for the couple, the two have remained strong since Kaitlynn confirmed their romance in December 2020.
"I have a boyfriend and we've been dating since May and everything is going really well," Kaitlynn told iHeartRadio's Scrubbin' In podcast at the time. "A lot of friends will ask me, 'How is everything going?' and all I can ever say is, 'It's going really well,' because it's like the most seamless, chill relationship."
