A mother of 12 added not one, but four children, to her brood today in Australia.

The 48-year-old woman from Melbourne gave birth to two boys and three girls via Caesarean section. A fifth infant, a daughter, however, died in the womb.

The babies, who were reportedly conceived naturally, were born 13 weeks premature.

A team of 30 medical specialists participated in the delivery at Monash Medical Centre.The hospital said the surviving babies were born healthy.

"Mum is doing well," a hospital spokesman told the Australian Associated Press.

The family did not want to be identified, but the AAP said that the quints were the first set to be born in Victoria in 30 years.
