How am I supposed to do this

Almost a year old now! But takes 4 bottles a day like 5 to 6oz each. Still wants a bottle in the morning and before bed and when she wakes from. His naps she usually cried till she gets a bottle of formula.

How do we switch? Her appointment is soon so I'll ask them but how did u moms switch? Did they act starving without it? If they have one first thing in the morning do they need milk first thing?

Also she won't hold her 360 cup or straw cup for an extended time. To make her Drink water I have to hold it still or she throws it as hard as she can. How am I gonna get her to drink milk if she does this?

And do u still track it? I track every feeding sippy cups don't have measurements so how do I measure and know how much milk to give

*edit I didn't say she doesn't eat food... She does! 3x a day
