The Buthelezi children are only the fifth set of quins born in South Africa since 1960, Clinix Health Group, which runs the hospital where they were born, says.

 Well done to Dr Moeng Pitsoe and the medical team at Clinix Botshelong Empilweni Private Hospital on the successful delivery of our newest members of the Clinix Family. Join us as we congratulate the proud parents and wish them all of the best for the future!

The five children - named as Siyanda, Sibahle, Simesihle, Silindile and Sindisiwe - were born at 30 weeks, in other words, 10 weeks early.

But this is not unusual for multiple births, according to Clinix.

Each of the babies was more than a kilogram at birth and they are now breathing on their own and are steadily gaining weight, Clinix says.

"Best practice tells us with these factors on our side, the babies have the best chance of survival," lead physician Dr Moeng Pitsoe said.

"We expect that these quintuplets will be the first set [in South Africa] where all survive and steadily achieve their developmental milestones," he added.

The babies will be able to leave hospital after they reach 2kg.

 "Once again Clinix has delivered on its commitment to providing quality, affordable healthcare to peri-urban communities. We wish the parents and the healthy quintuplets all the joy and happiness"…Said Dr Khamane ‘Kop’ Matseke, Clinix Health Group CEO.
