Michael and Hannah Carmack ought to buy a lottery ticket.

The Alabama couple welcomed quadruplets into the world, but more than that, Hannah Carmack gave birth to two sets of identical twins — two boys and two girls.

The odds of having two sets of identical twins in the same birth without fertility treatments, as Hannah did, is about 1 in 70 million.

Michael Carmack recounted Hannah Carmack’s reaction at her first ultrasound appointment when the couple learned they would be having not one baby, but four.

“She was like, ‘Twins?’ But the ultrasound tech didn’t respond. Then Hannah goes, ‘Is it three?’ Then the ultrasound tech put her hand on Hannah’s knee and said, ‘Sweetie, it’s four,’” Michael told Today. “I started laughing. Hannah started to cry.”

The Boaz couple, who also have an 8-year-old girl, Emily, had differing opinions before the pregnancy on how large the size of their family should be. Michael Carmack’s dream was a big family while Hannah Carmack wasn’t so keen on the idea.

They decided to consult their pastor.

“What I think Hannah came to realize is, ‘This is not normal. We had been chosen for something by God,” Michael Carmack told Today.

Efforts to reach the Carmacks were unsuccessful.

Hannah Carmack, 29, gave birth in March 14 to twin girls Evelyn and Adeline and twin boys David and Daniel via cesarean section at the UAB Women and Infants Center in Birmingham.

The quadruplets are expected to remain at UAB until their technical due date next month. The babies need help with eating, but the 2-month-old quadruplets are breathing on their own.
