California - A baby born weighing just 245g (8.6oz), believed to be the tiniest on record to survive premature birth, has been discharged from hospital in the US. Baby Saybie weighed the same as a large apple when she was born at 23 weeks and three days in December 2018.

Fighting for life, she was transferred to the intensive care unit at Sharp Mary Birch Hospital in San Diego, California.

Doctors told Saybie’s parents she had just hours to live.

But five months on, she was discharged weighing a healthy 5.6 pounds (2.5kg), confounding all expectations.

‘I didn’t think she would see Christmas’ Parents’ care ‘can help’ premature babies A nurse who cared for Saybie as she battled for survival said her recovery and release earlier this month was a “miracle”. vThe Tiniest Babies Registry said Saybie is thought to be the world’s smallest surviving premature baby.

The previous record was held by a baby girl from Germany, born weighing 252g (8.9oz) in 2015, according to the registry, operated by the University of Iowa.

A baby, born weighing just 268g (9.45oz) in Japan earlier this year, is thought to be the smallest boy to have survived premature birth.

Saybie’s mother gave birth to the little girl by emergency C-section three months ahead of schedule after she was diagnosed with pre-eclampsia - a pregnancy complication involving high blood pressure which can prove fatal for mother and baby. In a video released by the hospital, the mother described the birth as the “scariest day of my life”.

“I kept telling them: ‘She’s not going to survive. She’s - I’m only 23 weeks [pregnant]’,” the mother, who has chosen to remain anonymous, said.

Saybie weighed 245g (8.6 oz) and measured 23cm (9 inches) when she was bornHer birth was so premature, doctors considered her a “micro preemie” - a baby born before 28 weeks’ gestation. Babies are typically born between 37 and 42 weeks into pregnancy, the hospital saidShe was so small she could “fit in the palm of the hands of her care team”, it said. Her survival, doctors believe, could be attributed to the fact that she suffered no serious complications after birth. “Saybie experienced virtually none of the medical challenges typically associated with micro preemies, which can include brain bleeds, and lung and heart issues,” the hospital said.
