Cows milk :/

Okay so I’m finding it really hard switching. But my girl loves the cows milk warm and at night has a whole bottle ! However getting it in her through the day time is so hard, she eats very well ! Loads of good healthy food and she has her three meals a day alright 😂 But this milk thing really gives me anxiety I feel I’m doing wrong, she’s not getting what she needs :’( How many bottles of milk should she now have daily ? Any advice. I’m sorry I sound so stupid :(
