Jessica Graf and Cody Nickson have a big reason to celebrate once again.
The Amazing Race winners and Big Brother fan-favorites welcomed their second child into the world this week. According to the couple's announcement post, Carter York Nickson was born on Monday, Oct. 5, weighing in at "7lbs 2oz 19.5 inches."
The couple's baby girl—who was originally expected to arrive by Oct. 15—joins older sister Maverick, 1. Cody also has an eight-year-old daughter named Paisley from a previous relationship.
It's a big announcement for a couple who first fell in love in the summer of 2017 while competing as total strangers on season 19 of Big Brother. The pair would tie the knot in October 2018 before appearing on—and winning—season 30 of The Amazing Race.
"I just want to keep going with the kids," Cody shared with E! News while attending the 2018 E! People's Choice Awards. "We want to knock them all out and be young parents."
Jessica added, "I want to be surrounded by babies. I want to lay on the couch and have babies everywhere to just cuddle."
This past summer, however, Jessica was honest about how she was feeling before raising two kids under two. In a candid Instagram post, the CBS reality star admitted to feeling a little "overwhelmed."
"We're about to have two little girls under the age of two and I must admit I'm feeling a little overwhelmed," she wrote on Instagram. "I have no idea if I'll ever have a good night's sleep again. I'm worried about sleep training a newborn all over again and I'm nervous that bringing another baby into the mix might throw Maverick into a sleep regression."
Fortunately, Jessica has a supportive husband who remains her biggest cheerleader in and out of the Big Brother house.
"I want to share my appreciation for my wife. She is halfway through pregnancy and is doing amazing with I," Cody shared on Instagram in June. "My wife had made our house a home and I love and appreciate her so much for it."
