My absolute favorite newborn cover is the NB Nikky cover. It is one of the few covers that has a cutout for the cord and they are sooooo soft and gentle. My babe was nearly 10 lbs at birth and the Nikky cover fit him for several weeks over his fitteds. The elastic was very gentle as well, but gave a nice snug fit. I got the cotton covered ones from Zabi Baby, but looks like maybe they're closed ATM. I had Thirsties, WeeHuggers, Bummis, and Blueberry covers as well, but the Nikky were the best.
