Richard Walker Sault was born two days before Christmas, at Saddleback Memorial Hospital in Laguna Hills.
Weighing 14 pounds, 2 ounces, officials say Richard is one of the biggest babies every born in Orange County.
He was delivered via C-section, and it took two doctors to lift him up during the operations.
Although he has an older sister who was more than 10 pounds, even his parents were suprised by Richard's size. His dad, Richard Sault, said his daughter was walking at 10 months and he half-expected little Richard to get up and walk out of the hospital!
