A girl born after just under 22 weeks in the womb – among the shortest gestation periods known for a live birth – will remain in a hospital a few extra days as a precaution, officials said. Amillia Taylor, who weighed less than 10 ounces (283 grams), had been expected to be sent home this week. However, routine tests indicated she was vulnerable to infection, said Dr. Paul Fassbach, who has cared for the baby since shortly after she was born.

“She has been fine,” Fassbach said, but doctors are being extra cautious “now that she’s going into the world.”
