First time mom with a NB

Kelcie • I`m Kelcie! 20 year old mommy to an 8 month old girl.
So my daughter is a week old and she's 7 pounds 2 ounces. When she came home from the hospital she drank 1-2 ounces every 2-3 hours. Now she's gulping it down like nothing and wanting more. Is 4 ounces too much for her to have at a time?
