BEIJING — A mother in central China has given birth to a 15.52 pound baby, possibly the largest newborn on record since the country's founding in 1949.

The state-run Tianjin Post said Tuesday that the 29-year-old mother in Henan province gave birth to the boy Saturday by cesarean section. It said delivery took just 20 minutes and both mother and the baby, named Chun Chun, are doing fine.

The paper said Chun Chun's parents are average size and there was nothing unusual about his mother's pregnancy or diet.

The paper said it wasn't immediately clear whether Chun Chun made China's record books.

Guinness World Records says the heaviest newborn ever recorded was born to an Ohio woman in 1879 and weighed 23.7 pounds.
