The girls, aptly called Hope and Faith, were born on Thursday.

Proud parents, Renee Young and Simon Howie, of Tregear in Sydney’s west, were originally told to abort the pregnancy after discovering their babies had a rare genetic disorder during their 19-week ultrasound.

Faith and Hope have disrosopus, where the embryo fails to split in the early stages of pregnancy.

There are two faces on one skull and exact duplication of eyes, nose and mouth and two brains, connected with one brainstem.

“Even though there is only one body, we call them our twins,” dad Simon told Women’s Day. “To us, they are our girls and we love them.”

Mum told A Current Affair: “I think they are beautiful and Simon thinks they are beautiful so really that’s all that matters.”

Disrosopus is so rare that only 35 cases have ever been recorded and none have survived.
