There's a new baby in Elmira, N.Y, and she's got a big story to tell. A very big story.

Harper Buckley is one-week-old, and she's already breaking records.

According to Arnot Ogden Medical Center, she's the biggest baby born there in at least 30 years.

Harper was 15 lbs., 5 oz. at birth.

Harper was double the average weight of a newborn in the U.S. and was taken to the Neonatal Intensive Care Unit to have her sugar and oxygen levels monitored, but she appears to be fine.

"I knew she was going to be big, but I did not anticipate no 15 pound baby," said mom Joy Buckley.

A few years ago, her mom and dad had an 11-pound baby boy. That's 26-pounds of baby in just two infants.
