15.5-Pound Baby Chun Chun and Other Heavy Babies at Birth

At 15.5 pounds, baby Chun Chun is China's heaviest baby. He was born on Saturday, in the city of Xinxiang in the country's Henan Province.

Chun Chun's mother Wang Yujuan, 29, delivered the 15.5-pound baby via C-section, which lasted about 20 minutes, according to reports.

I clearly felt that my body was more clumsy than when I had been pregnant with my daughter. My belly was bigger than it was then, Wang told the media. I guessed the baby would be between 10 and 11 pounds. I never expected to hear that he weighs 15.5 pounds.

Chun Chun's younger sister is now 6 years old and weighed 8.8 pounds at birth.

Han Jingang, the father of the 15-pound baby boy, told UK's The Sun newspaper that his wife didn't do anything out of the ordinary during her pregnancy.

She ate and drank normally as she should, Jingang said. But she's given birth to such a big, fat son.

Today is the first day of spring in the Chinese calendar and he's a 'dragon baby,' Jingang added. I feel very happy.
