Bottle to Sippy/Formula to Milk

My daughter turned 1 on the 1st, so I decided it was time to drop the bottle and switch to milk, only problem is I don’t know how to go about it. She’s been drinking water out of a sippy with meals since she was 6 months old and her typical eating/drinking schedule is as follows

Bottle first thing in the morning

Sippy with water at breakfast

Bottle after noon nap

Sippy with water at snack time around 3

Sippy with water at supper

Bottle about 30 minutes before bed

So this morning I tried doing 4oz of formula and 2 oz of milk in a sippy first thing when she woke up, she took like two sips and decided it was not for her, so I poured it into her bottle and she drank it all

We see her pediatrician on Monday so I will get her input then but wanted to see how other moms went about it
