A mother in central China has given birth to a 15.5-pound baby boy -- possibly making him the heaviest newborn in the country's history.

The 29-year-old mother in Henan province gave birth to Chun Chun on Saturday by cesarean section, the state-run Tianjin Post reported.

The procedure took just 20 minutes and mother and baby are doing fine, according to the Post.

Chun Chun's parents are average size and there was nothing unusual about his mother's diet while pregnant. It wasn't immediately clear whether the baby had made China's record books, the Post reported.

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