J., there's two really helpful books I highly recommend that you get in understanding your daughter's fussiness. But first, just to help you understand that your daughter is trying to adjust being outside the womb when ultimately her nervous system was not prepared for it. Even when babies are born at 40 plus weeks, they are not as ready for the outside world as they should be. Because human babies' heads are so large we are forced to have our babies a trimester earlier than they are ready. Have you ever heard of the 4th trimester? Lucky in some ways we don't have to carry our babies for another 3 months! However, biologically they would be a lot happier if we could.
So, your daughter is just releasing stress from having to deal with the stimulation - the cold, the fluctuating warmth, digesting milk, taking in images, hearing noises so clearly, etc. and her only way to release stress is by crying.
You are doing the right thing by comforting in-arms as much as you can. She doesn't need you to stop her from crying, she needs your consistent comfort. Make sure to swaddle her and keep stimulation at a minimum. She is missing the womb! =)
Two books I think are brilliant on the subject of crying and soothing babies -
Tears and Tantrums by Aletha Solter
The Happiest Baby on the Block by Dr. Harvey Karp
A really excellent website with invaluable information about infant sleep is at www.hugyourbaby.com
