A set of twin boys in Kansas were born 39 days apart.
Elene Cowan gave birth to her son Carl when she was just 24 weeks into her pregnancy.
Her son weighed a mere 1.4 pounds when he was delivered.
He was so tiny that Cowan could slide her wedding ring over her baby’s wrist.
“I thought that he would die and this really isn’t a baby,” Cowan recalled. “There’s no way he’s going to make it.”
Doctors were able to keep Cowan’s other son, David, in the womb longer by using a special balloon and medication.
Cowan remained on bed rest and only got up to visit Carl in the neonatal intensive care unit.
Nearly six weeks later, David was born, weighing 2.9 pounds.
“It was like those things you hear about happening but you never expect it to happen to you,” Cowan told ABC News of the complicated delivery.
The babies are now four and six months old. Carl still needs oxygen, but the twins are doing well.
Another set of twins also made headlines recently after they were born 24 days apart in Boston.
Alexandre and Ronaldo Antunes are expected to be released from the hospital in time for their June 18 due date.
