Saybie has been released from a California hospital, officials revealed on Wednesday.
After almost five months in a neonatal intensive care unit, the baby girl, who was nicknamed Saybie by the staff, left the San Diego hospital earlier this month and instantly earned a place in the history books.
Saybie was born prematurely at 23 weeks and 3 days of gestation weighing about as much as a large apple. But five months on, she was discharged weighing a healthy 5.6 pounds (2.5kg), confounding all expectations.
Dr. Edward Bell of the University of Iowa, which maintains the Tiniest Babies Registry, confirmed that Saybie is the world’s smallest surviving premature baby the registry has ever recorded.
Saybie was about 7 grams lighter than the previous smallest baby, who was born in 2015 after 25 weeks of gestation in Germany, according to the registry.
“Baby Saybie has the lowest birth weight among the infants in the Tiniest Babies Registry,” Bell told NPR. “The registry contains only those infants submitted and medically confirmed. We cannot rule out even smaller infants who have not been reported to the registry.”
The father was told by doctors that he would have about an hour with his daughter before she passed away.
“But that hour turned into two hours which turned into a day, which turned into a week,” the mother said in a video released by the hospital.
Doctors said Saybie was delivered via emergency cesarean section in December at 23 weeks and three days gestation in the womb after severe pregnancy complications that put her mother’s life at risk. A typical pregnancy lasts 40 weeks.
“She’s a miracle,” said Kim Norby, a nurse in the hospital’s neonatal intensive care unit. “That’s for sure.”
