The little girl, named Saybie, weighed roughly the same as an APPLE when she was born at a San Diego hospital in December.
She was born 23 weeks and three days into her mother’s 40-week pregnancy.
Doctors told her distraught mum and dad after the birth that they would only have about an hour with their girl before she died.
But Saybie’s mum said: “That hour turned into two hours, which turned into a day, which turned into a week.”
The delighted new mother, who does not wish to be named, appeared in a video announcing the miraculous survival.
It was released last night by Sharp Mary Birch Hospital for Women & Newborns.
GOING HOME HEALTHY
More than five months have passed since the birth – and little Saybie has gone home as a healthy 5lb infant.
The baby’s family gave permission to share the story but wanted to stay anonymous, the hospital said.
They allowed the girl to go by the name that nurses called her: “Saybie.”
Her ranking as the world’s smallest baby ever to survive is according to the Tiniest Baby Registry, maintained by the University of Iowa.
