A husband and wife, Peter and Kate Hill were struggling to conceive. In 2006 Mrs Hill has diagnosed with polycystic ovarian syndrome: a hormonal condition that left her unable to ovulate. She underwent hormone treatment and fell pregnant, not once, but twice.
It was a medical phenomenon so rare there are only 10 medically documented cases of it in the world. Mrs Hill conceived two babies, 10 days apart. The conception is called superfetation, which essentially means she fell pregnant while already pregnant.
The rare conception started as a single pregnancy with twins, before she conceived again 10 days later to be pregnant with triplets.
Sadly the couple lost one of the babies early on in the pregnancy, and the Hills were given two due dates, December 20 and December 30 2015.
Their adorable girls, Charlotte and Olivia, were born together two days before their scheduled caesarean.
The incredible birth was captured by 2016 Australian Birth Photographer of the Year, Selena Rollason in a series of black-and-white images.
The girls measured very differently in size, weight and gestational development. They are now 10 months old, and their loving parents told Today Tonight they have different blood types.
Mrs Hill’s obstetrician, Dr Brad Armstrong from Greenslopes Private Hospital in Brisbane, said he had never seen a case of superfetation before.
He told Today Tonight it was so rare he could not find any literature about it on medical websites, and was forced to Google the condition.
