After five years of trying and a lot of begging from their 8-year-old son, Gavin and Carrie Jones were thrilled to learn they were expecting another child, but they weren't betting they'd be having five more at once.

The Joneses knew twins were a possibility since Carrie had taken fertility shots, but when the couple counted not three, not four but five babies during a sonogram, they did the only thing they said they could do- laugh.

"It was an extreme surprise," Gavin said.

On August 9, nearly 28 weeks into her pregnancy, Carrie delivered three boys and two girls via Cesarean section at the University of Texas Southwestern Medical Center in Dallas.

"The delivery took a little less than five minutes. It was 10:01 would they did the incision and it wasn't yet 10:05 when they were all out," Gavin said.

Will Edward, David Stephen, Marcie Jane, Seth Jared and Grace Elise are being cared for in the neonatal intensive care unit at St. Paul University Hospital, a branch of the medical center where they are expected to remain for the next seven or eight weeks, their father said.

Their birth weights spanned from 1 pound, 12 ounces to 2 pounds, 11 ounces.

Dr. Patricia Santiago-Munoz, assistant professor Obstetrics/Gynecology at the University of Texas Southwestern Medical Center, said she sought advice from a doctor who had previously delivered quintuplets,adding that the delivery was "relatively smooth."

"It was pretty routine, other than pulling five babies out of a uterus. It was the same incision you would do for everyone else and she didn't bleed more than usual," Dr. Santiago-Munoz said.

The couple documented their pregnancy on a blog, where they have continued to provide updates on their five new additions.

After growing from three members to eight, the Jones clan knows they'll need plenty of help.

The family, who is based out of Papua New Guinea, where Gavin and Carrie do missionary work for Wycliffe Bible Translators , are currently living with Carrie's parents.

"Her family is going to be helping. We're just asking for volunteers to help hold, change and feed the babies. It is nothing thre three of us can handle on our own," Gavin said.

The family hopes to return to Papua New Guinea in the middle of next year to continue their missionary work.

"We anticipate our lives there will be simpler and cheaper," Gavin said. ""But we're definitely not looking forward to the trip over with five babies!"
