"I was induced with my other pregnancies so with this one I wanted to see what it was like going into labor naturally," Corrigan told InsideEdition.com. "We knew he was going to be bigger because I carried big, but we assumed he’d be no bigger than 11 pounds."

So when Corrigan, who had no medical problems during pregnancy, was informed of Brian Jr.’s weight, she was flabbergasted.
