is she really this hungry???
My baby is 5wks old today and she is insatiable!!! She spends over an hour nursing, empties both breasts and then will take a 2 oz bottle!!! It's insane and I feel like I'm spending hours feeding her! And I know I'm producing enough, when I pump I get like 4oz every time. Her Dr said because she was premature its hard to gauge when she'll have a growth spurt, but I think that's what's happening. Any advice or insight???

If it's breast milk in a bottle you'll want her to continue on the breast so she can get your supply up and going.
I've been told when they go through a growth spurt they are also extra cranky because they are constantly wanting to nurse and are hungry.
Below is a link to a site that is from the Le Leche League there is so much information on that site to help.
Also, if you can maybe while you give her a bottle try pumping and see if you can get anything to come. Or keep trying to get her to latch onto your breast so she can trigger your body to start producing more.
