Cynthia Sigler, a Southern California woman, knew for months that she was going to have a big baby but she never expected a nearly 14-pound baby boy she has named Jayden. (See photos here.)

When Jayden Sigler was delivered by c-section on Thursday, he weighed in at 13 pounds, 14 ounces and was a healthy baby, the North County Times reported.

How'd he fit? Cynthia Sigler said was her immediate reaction.

Doctors had warned Cynthia Sigler that she was going to have a big baby. They just didn't know how big the boy would be. Inital estimates were that Jayden would be born weighing about 9 pounds. However, by March the number increased by two pounds, the mother told the newspaper.

Jayden's birth weight is almost twice the size of his sister, Jailyn, 2, who weighed 7 pounds, 2 ounces at birth.

Dr. Jerald White delivered the baby at Tri-City Medical Center. The center's longest-serving doctor, White told the North County Times that Jayden was the biggest of the 20,000 newborns he delivered since his career began in 1961.

While White said that delivering a very large baby through c-section is more difficult, he said it wasn't so difficult that it created a problem for anybody.

White also said that the largest baby he had delivered before Jayden weighed 12 pounds, 7 ounces.

On Friday, hospital officials weren't able to tell whether Jayden is the largest baby ever delivered at Tri-City.

The largest baby ever delivered was a baby born at 23 pounds, 12 ounces in January 1879, according to the Guinness Book of Records. That newborn died 11 hours after birth. The largest surviving birth was a boy born in 1955 who weighed 22 pounds, 8 ounces, according to Guinness Book of Records.

Cynthia Sigler said she will now have to exchange all the baby clothes she bought and get larger sizes.
