Dr. Jerald White, who delivered the baby at Tri-City Medical Center, said Jayden was the biggest of the 20,000 newborns he has helped usher into the world since he started in 1961.
The doctor said delivering a very large baby via cesarean section is more challenging, but "it wasn't so difficult that it created a problem for anybody."
Sigler said her own family didn't believe her at first — she convinced her cousin it wasn't a joke only after showing a photo of the scale readout.
Jayden's birth weight is almost twice that of his sister, Jailyn, now 2½. She was 7 pounds, 2 ounces at birth.
Sigler said she'll have to exchange all the baby clothes she bought for larger sizes.
