Nothing quite compares to taking on the role of parenting two toddlers. So when Christie Mullin approached her husband, U.S. Rep. Markwayne Mullin , R-Okla., suggesting they adopt twin girls , he had his answer prepared.

“I said, ‘No babe, don’t even go there,’” Mullin told The Oklahoman . “I said, ‘Look, do you remember I’m in D.C. all the time now, do you remember that you’re raising three kids by yourself, do you remember you just recently had to pull your first calf? You remember you’re taking care of the farm now? Do you remember how much more responsibilities you have with the business now? Do you remember all these different responsibilities?’”

The girls were born into “kind of a bad situation,” according to The Oklahoman, and had been living in separate homes since they were infants. They were left in the care of their great-aunt and great-grandmother, both Christie’s distant relatives.

Christie told him to pray about it.

The Mullins invited the twins to their home for Christmas, and the “beautiful little blonde girls” charmed him. “I saw the twinkle in her eye and said, ‘Aw crap,’” the congressman told The Oklahoman.

“If you talk to anybody, they say twins need to be together,” Mullin said. “The bond between them is just amazing.”

“People say, ‘Man, you’re going to be such a blessing to those girls,’” Mullin said at a town hall meeting last week according to The Hill . “And I’m going to tell you right now — if you’re someone who’s thinking about adoption — you’re going to be blessed more by them than you will ever be a blessing to them.”

The girls, Ivy and Lynette join the Mullins’ other three children, Jim, 9, Andrew, 8, and Larra, 5. The adoption was final on August 21, and Mullin said his family “could not be happier.”
