A Russian woman gave birth to a baby of 7.75 kg in the Altai region in Siberia on Sept. 17, who is the 12th child of her's, according to foreign media reports Thursday.

The baby named Nadia stunned her parents after delivered by caesarean section in the local maternity hospital.

"We were all simply in shock," said Nadia's mother, Tatyana Barabanova, 43. "What did the father say? He couldn't say a thing -- he just stood there blinking."

"I ate everything, we don't have the money for special foods so I just ate potatoes, noodles and tomatoes," she said, adding that all her previous babies had weighed more than 5 kg.

Before Nadia, Barabanova had eight girls and three boys.

The Guinness World Records lists a 10.2 kg baby boy born in Italy in 1955, and a 10.8 kg baby boy who was born in the United States in 1879 but died 11 hours later.

The average weight for most healthy newborn babies is around 3.2 kg, according to World Health Organisation figures.
