You’ve heard of families who’s children’s names all start with the same letter, and the occasional family where a child has the same birth date as the mother or father, but what about a family who’s children were all born on the same day in different years?

Jenna and William Cotton of Marysville have an easy time remembering the birthday of each of their children. All of their three children have been born on October 2nd. The latest addition to the family was little Kayla who was born on Tuesday Oct 2nd. Her brothers Ayden Cotton and Logan Cotton were born on Oct 2nd 2003 and October 2nd 2006 respectively.

Based on that history, the parents said they had a feeling their baby daughter would come a couple of days past her Sept. 30 due date. Sure enough, Jenna Cotton, 23, began having contractions early Tuesday, hours before a planned birthday party for the boys.

She had a doctor’s appointment scheduled later in the day and hung in for the party. Ayden, the 4-year-old, wanted to know if his new baby sister would make the festivities, Jenna Cotton said.

“He has been really excited about her coming,” she said. “He kept asking when she was going to come out.”

He wouldn’t have to wait long. His mother’s doctor sent her to a hospital, where 7-pound, 8-ounce Kayla was born at 7:07 p.m. Tuesday.

The odds of a family having three children born on the same date in different years are about 7.5 in 1 million, said Bill Notz, a statistics professor at Ohio State University.

The Cottons don’t plan to roll the dice on a fourth Oct. 2 baby, saying that’s it for them, as far as having children.
