How much formula/breast milk does your 11 month old drink?

Hi! I have an 11 month old and I still offer her 6 oz of her formula every 3-4 hours. Sometimes she only drinks 4 oz.

Is this normal???? When do you stop offering so much? She eats 3 meals a day and I think she eats pretty well. I know some transition to cows milk at 1 years old. How much do they typically drink then? My baby won’t be going straight to cows milk as she has a milk protein allergy so I’m not sure what route my pediatrician will take.
