A pair of identical twins have another identical date to share: the births of their children.

Aimee and Ashlee Nelson of Ohio became new mothers on New Year’s Day after giving birth to two healthy children hours apart, Fox 8 reported.

The 19-year-old mothers from Ohio did not plan to give birth the same day. But despite the due dates being about a week apart, both Aimee and Ashlee Nelson went into labor on Tuesday at Summa Akron City Hospital in Ohio.

Aimee, whose expected due date was Jan. 6, arrived at the hospital at 3:30 a.m. Ashlee, whose due date was Jan. 1, was still at home.

“My mom told me that she was here and when I got up to go to the bathroom, my water broke so I had to come in too,” Ashlee told Fox 8.

Aimee Nelson gave birth to a seven pounds, two ounces son named Donavyn Bratten shortly after noon on New Year’s Day.

Then, about two hours later, Ashlee Nelson gave birth to an eight pounds, 12 ounces girl named Aiden Dilts.

“We didn’t think it was going to be this close at all,” Aimee said. “We tried getting induced together but they wouldn’t let us. That was like two weeks ago, but it happened anyway.”

“I think it was a big surprise,” Ashlee said. “But it definitely happened the way I would want it to happen, together.”

The twins themselves, according to Fox 8, were born 15 seconds apart 19 years ago. They learned about two days apart that they were both pregnant.

“We’re best friends,” Ashlee Nelson said. “Now our babies are going to be best friends.”
