The baby's father, Sabelo Khumalo, 23, told Sowetan his dream of becoming a first-time father was shuttered that day.
"When I saw my baby in pieces I couldn't believe my eyes because I had so much expectations. I had bought clothes in excitement," Khumalo said.
It would have also been Kgatla's niece's first child.
Kgatla said the family said her niece was told before birth that the baby had some abnormalities, but she was ready to raise the child regardless.
"I fail to understand why an emergency C-section was not performed. Instead, they pushed for a normal birth," said the uncle.
The Gauteng health department dispatched the provincial patients' safety team to the hospital to investigate the matter thoroughly and obtain facts from the medical team who were involved in this incident.
In a statement yesterday, the department said it noted with concern the reports about the macerated fetus at the hospital.
"Upon completion of the investigation, the department will communicate the outcomes and the recommendations. If necessary, disciplinary measures will be instituted," it said. "The hospital continues to offer counselling support to the patient and her family to help them deal with this unfortunate incident."
