How much formula for 7 month old?

I’m just curious how much your 7 month olds eat, as far as formula goes. My daughter will be 7 months in two day and she gets 6 oz every two hours. That seems like a lot to me! She starts screaming and freaking out right at that two hour mark though like she’s starving. And she gets mad when her bottle is gone and we take it. Lol.

She’s still tiny though. She’s had major spit up issues so she hasn’t gained weight very quickly. She’s only 14 pounds.
