Guiness World Records has got a new record holder for youngest preemie to survive. He was 21 weeks and 2 days gestation when he was born. Yup. 21! That's 3 weeks earlier than the usual cut off for whether or not doctors will attempt life saving measures or just comfort care for very premature infants. Not long ago nobody would attempt to give intensive care to any baby born under 24 weeks. I know that was the case 20 years ago when I was pregnant with my youngest and having early contractions (that turned into premature labor later on at 28 weeks).
