Lately my 10 week old has been FIGHTING sleep during the day to the point where she's miserable and cranky. It's really hard to get her to take a nap and it makes it really hard to get anything done. I feel like I've tried everything including making the room dark and playing white noise...is this normal for her age? It seems like since she's become more aware of the world that she has a hard time relaxing and falling asleep. Any advice mom's?!
