How many oz per day?

Mamas,

As usual I'm hearing so many conflicting things about how much milk my baby should be getting. I have an 8mo and we're on a pretty strict schedule:

8am nursing/5oz bottle pumped milk

10am solids (scrambles eggs/yogurt)

12pm nursing/5oz bottle pumped milk

2pm solids (fruit/veggies)

4pm nursing/5oz bottle pumped milk

6pm solids (yogurt/fruit/veggies)

8-9pm nursing

*I don't believe she's getting 5oz when nursing. My supply has dropped and while I can't know for sure, it's probably more like 3oz*

Am I way off here?? This is one thing we didn't discuss in my centering classes and like I said, everything I read is different.
