Twins are supposed to be born on the same day, then when they grow up they can fight over who was born a few seconds before the other.
One pair of twins won't have too much to fight over.
Having twins is already rare, but having them born at separate times will earn a pair of twins a spot on the Guinness Book of World Records.
Mrs. Peggy Lynn gave birth to her daughter Hanna on November 11, 1995, but she still had a boy to conceive as well! Hanna's twin, Eric, was born on February 2, 1996, which meant that these siblings held the title of the "longest interval between the birth of twins."
84 days sounds like a long time, but someone beat that title just a few years ago!
