Someone has claimed that they know of a 20 weeker (not a typo), that was in NICU when their own child was there. They claimed the baby was 1 pound (which is double the weight of a 20 week gestation baby) and that it spent 4-5 months in NICU before going home!
I would like to believe it but know that if it was true - it would have been splashed all over the newpapers and news. Have you ever heard of a 20 weeker surviving?
