My 6 week old has been sleeping for 15 hours. I’ve been waking her up for feedings but this is unlike her to sleep this much! Since birth she hasn’t been the best sleeper so this is a surprise to us and we’re not sure if it’s normal or not lol she has her days and nights mixed up and stays up way more than normal newborns. Sometimes she’s up for 6 hours with a couple 15 minute naps between
