(VOORHEES, N.J.) -- Twin sisters from New Jersey were so in sync they even ended up having their babies within minutes of one another.
Stephanie Edginton and Nicole Montgomery welcomed their daughters, Cora and Louisa, respectively, on Monday at the Viruta Hospital in Voorhees, New Jersey.
Edginton said she was actually overdue when she delivered on Monday.
"We actually had a doctor's appointment today because we were due on Friday," she told ABC's Philadelphia station WPVI-TV. "We got there and they were like 'you have to go to the hospital' and we get a call that Nicole and Rich are on their way, too."
The sisters told WPVI-TV they were born just three minutes apart. Their two daughters may have doubled that time by being born six minutes apart, but these first cousins will still share a birthday.
The couples did not immediately respond to requests for comment from ABC News sent through the hospital.
