Having one set of twins is unique enough, but a Mitchell woman recently found out she's expecting her second set of identical twins and the chances of that are one in almost 63,000.
Corey and Kristin Haisch have had a lot of surprises inside the ultrasound room. One of those was when they found out they were going to have twins three years ago.
"[We were] not really sure what to think at first," Corey said.
But two-year-olds Tarryn and Madelyn have been quite the double blessing.
"It's hardest when they're babies, and once they get past the crawling stage they always have someone to play with," Kristin said.
"Madelyn is definitely a girly girl and Tarryn is my little tomboy," Corey said.
Corey was hoping to even the score a little bit and have a boy next, but ultrasounds would reveal his wife is not only having one girl, but two girls.
"I kind of had to start laughing because it would just be my luck that I'd have another set of twins," Corey said.
More mothers in South Dakota are giving birth to twins, but Dr. Ashley Briggs says that's because of an increased use of fertility drugs.
"The gestational age, the days at which the fertilized egg splits, is how you determine whether you have twins and what types of twins you have. Sometimes there can be an increased risk if it runs in your family and again most commonly we see it with fertility drugs," Briggs said.
But Kristin never was on fertility drugs and neither Corey nor Kristin have a family history of multiple births.
"It took a while to finally be okay with the fact that we're having twins again. It's nerve-racking, but we're excited," Kristin said.
But that hasn't been the only bump in the pregnancy road. Kristin has what you call twin-to-twin transfusion syndrome. It occurs when blood moves from one twin to the other. But thankfully Kristin's babies' fluid levels have evened out and the doctor says they're healthy.
And as far as four girls under the age of three in one house, Corey says he’s okay with that.
"As long as they're healthy, that's fine with me," Corey said.
Corey says even though they're not born yet, he's already falling in love with his twin set of twin girls.
"I'm wrapped around their fingers. They're wrapped around mine. They've touched a pretty sweet spot in my heart. I'd never give them up for anything," Corey said.
Corey says he would still like to have a boy, but he's not sure yet whether they'll try to have any more children.
