The two infants were born a week apart.
Jennifer Renz of North Canton went into labor while at her doctor's office on March 22. She wasn't due for another 12 weeks but gave birth at a Cleveland hospital to a 1-pound, 13-ounce girl, named Grace.
Doctors say at that point things kind of stopped, with the other baby, a boy, still in the womb. They decided not to induce labor but allow the second child more time to grow inside his mother.
"The whole time," Lenz says, "I wanted them to have separate identities and be separate people, and now, they have their own separate special days."
Little Noah didn't arrive for another seven days, weighing in at 2 pounds, 15 ounces. Both infants are now in a neonatal intensive care unit.
Their father, Dennis Renz, says he and his wife plan to celebrate the birthdays separately.
