The world’s smallest surviving baby has been discharged from the hospital five months after she was born at just 23 weeks gestation, according to the hospital.

Baby Saybie, who was born in December 2018, weighed just half a pound when she was delivered at the Sharp Mary Birch Hospital for Women & Newborns in San Diego, according to a press release by Sharp Health. Saybie weighed 5 pounds when discharged.

Her mother underwent an emergency cesarean section after she experienced severe pregnancy complications and doctors determined that the baby was not gaining weight and the mother’s life was at immediate risk.

“It was the scariest day of my life,” Saybie’s mother said in a video released by the hospital, adding that doctors told her that she was suffering from preeclampsia and very low blood pressure. “I just felt very uncomfortable, and I thought, maybe this was part of the pregnancy.”
