No matter what you wanna feed her whenever she wants to eat because she's really the only one who knows whens she's hungry. Nursing, they usually eat all the time and are attached to you like a body part. Bottle feeding, four ounces at least every 2 hours if not more if she wants. Remember that she has a lot of growing to do. It's all about trial and error, if she spits up a lot then limit her eating a little. A little spit up is ok so don't worry bout that too much.
