She should be allowed to eat until full and on demand. I never counted the number of oz my kids drank. They were breast fed and formula fed. However, I would always offer up 4 oz or so and when they pushed the bottle away they were done. People become consumed with my kid eats this much or that much. Let her eat until she's full. When she's done she'll stop. Don't count oz's every child is different and so are their nutrional needs.
