LONGVIEW, Texas (AP) — A Texas mom expected a big baby, but nothing like this: 16 pounds, 1 ounce.

Janet Johnson on Monday remained in an East Texas hospital after giving birth to what her doctors called one of the biggest newborns they’ve ever seen. She was awaiting word on whether her son, JaMichael Brown, ranked among the biggest births in state history.

“Everybody was amazed that he was so big,” Johnson, 39, said. “I don’t think too many people have heard of having a 16-pound baby.”

JaMichael was born Friday at Good Shepherd Medical Center in Longview. Johnson has gestational diabetes, which results in bigger newborns for many mothers. Doctors had estimated JaMichael would be around 12 pounds prior to the cesarean birth.

The hospital has asked the state’s vital records department whether JaMichael is big enough to approach any Texas newborn records, said Victoria Ashworth, a hospital spokeswoman. He is certainly the biggest in the history of the Longview hospital and was born, Ashworth said, almost two years to the day after the hospital delivered its smallest baby ever, who weighed just 15 ounces.

Guinness World Records says the heaviest newborn ever recorded weighed 23 pounds, 12 ounces, born to an Ohio woman in 1879.
