"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 Sharp Mary Birch Hospital for Women & Newborns.
The hospital said the girl officially weighed 7 grams less than the previous tiniest baby, who was born in Germany in 2015. After almost five months in the neonatal intensive care unit, Saybie's parents, who wished to remain anonymous, took their "healthy 5-pound infant" home earlier this month, the hospital said.
Just last month, a CT preemie made headlines when he was able to head home after growing from 11 ounces to 11 pounds during nine miracle months at two Westchester hospitals. "But when the unexpected occurs, Sharp Mary Birch is equipped with the latest technologies, equipment, research, and specially trained experts to care for even the world's smallest baby".
Babies born before 24 weeks, micro-preemies, experience more medical problems than babies born later, including brain bleeding and poor heart function.
She said she was rushed to hospital after feeling ill and was told she had pre-eclampsia - a condition marked by very high blood pressure that puts both the mother and baby's lives at risk. But that hour turned into two hours, which turned into a day, which turned into a week, ' the baby's mother said.
Doctors said Saybie experienced "virtually none" of the medical complications that typically come when a baby is born as a "micropreemie", which refers to babies born before 28 weeks of pregnancy.
Wozniak said the hospital has had its fair share of "23-weekers", but Saybie's diminutive size, which was caused in part by the preeclampsia, made her situation all the more challenging.
"We should celebrate this date every time", the mother said.
After Saybie was born, doctors told the father that he had an hour to spend with his child before she died.
But she did. The tiny girl slowly gained weight in the neonatal intensive care unit.
"She's a miracle, that's for sure", said NICU RN Kim Norby.
Saybie's ranking as the world's tiniest baby ever to survive is according to the Tiniest Babies Registry, maintained by the University of Iowa.
