"I'm so excited, they're going to be such great parents," says Christine. "I know they're a bit overwhelmed because it's twins, it's a lot of work but I live close, Aspyn lives close."
"She's got such an amazing support system, we're all so excited," she continues. "They've been incredible parents with Avalon and now we get to see them be parents again!"
Mykelti and Tony, 27, welcomed their first baby together, daughter Avalon, on April 5, 2021, a TLC rep confirmed exclusively to PEOPLE at the time.
"We are both very happy with our baby and the success of our home delivery. We were excited [sister wife] Robyn [Brown] could join us via Zoom for the whole labor," Tony told PEOPLE. "My wife's the strongest person I know and it shows."
Mykelti added, "Avalon is gorgeous, enjoyable and full of life."
The couple tied the knot during a large ceremony in December 2016. They said "I do" in front of more than 400 guests, holding their ceremony at the Bloomington Country Club in St. George, Utah. They followed it up with a Mexican vintage-themed reception.
