Born at Miami, Florida, in October 2006, little Amillia Sonja Taylor survived despite a gestation period of fewer than 22 weeks. She spent 21 weeks 6 days in the womb (full-term births are between 37 and 40 weeks) and at birth weighed less than 10 oz (284 g) and measured just 9 1/2 in (24 cm) long —  that’s only slightly longer than a ballpoint pen.
