ER24 spokesperson Russel Meiring said paramedics were called to the scene by local authorities.
When they arrived about 8.15am they found the woman lying on the floor, while a nine-year-old girl, a five-year-old boy and seven-month-old boy were found lying in their beds.
“It was evident that all four had been dead for some time they were pronounced dead,” said Meiring.
The details remain sketchy, but local authorities are investigating.
