A British mother might have entered her name in the medical history by giving birth to triplets from two wombs. Hannah Kersey, 23, from Northam in Devon, gave birth to identical twins Ruby and Tilly, and singleton Gracie - by Caesarean section in September.

"This is so rare you cannot put odds on it," said Ellis Downes, consultant obstetrician at Chase Farm Hospital in London. "I have never heard of this happening anywhere ever before - it is quite amazing."

Kersey was born with a rare condition called uterus didelphys, which means she developed two wombs. According to doctors, only 70 women in the world are known to have been pregnant in two wombs in the past 100 years. But these births are the rare of the rarest since it is the first reported case of triplets in two wombs.

The girls were born seven-weeks prematurely and had to stay in the hospital for nine weeks. The girls are back home and said to be doing well.
