The twins who share everything but a birthday! Born 12 hours apart, these twins will be celebrating their birthdays on different days

Buffalo, NY: The Muldowney twins will share plenty of things in life, but the same birthday isn't one of them.

Tammy Muldowney gave birth to her first child, daughter Kennedy Clare, at around 7:30 p.m. Tuesday at Women and Children's Hospital in Buffalo.

Muldowney and husband Bryan, from nearby Hamburg, say they expected the second baby to be born soon afterward, but he wasn't ready yet. It would be nearly 12 hours later before twin brother Kellan Michael was born.

The doctor who delivered the babies says it's not uncommon to see twins born up to a couple hours apart, but 12 hours is rare.

Both babies are doing fine.
