American mother Lauren Vinje posted an adorable photo of her premature newborn and it instantly went viral on the Internet. "Our first daughter at five days old. 3 lbs 14 oz (1.7 kg), she was happy to be alive!" Lauren wrote. The little baby was below the average weight of a newborn (it ranges between 5.5 lbs and 11 lbs), but it didn't stop her from embracing life right from the start.
