She drinks about 6oz every 2-4 hours. If it's closer to the two hour mark she may not eat all 6oz and will only drink 3-4.

My daughter will be 2 months on the 30th and she pretty much drinks anywhere from 4-6oz every 4 hours or so.

Mine ate 4 oz at 3 months. He’s 6 months currently and he will eat 7-8 oz if he’s not eating cereal or baby food. If he has cereal or a jar of baby food then he will have 2-4 oz of milk with it.
