Anyone else having a hard time getting their babe to drink milk out of a sippy cup?

Penny will drink water, juice, smoothies, literally anything else out of her weighted straw cups, but the minute she sips milk out of it, she wants nothing to do with it😩

Kendra suggested I have a separate cup for just milk, so we’ve tried the 360, and I have the Nuk Mickey one with the handles, and she wants nothing to do with those either as soon as milk comes out🤦🏻‍♀️

I even put a straw in the Mickey one, and she took 2 sips, and then said “Baba” which is what she calls her bottle. I know she’s attached to the bottle, and we’ve got time to wean off it, but I’m just wondering if any other mamas are going thru this, or have had success with a specific method or cup?Ive been trying every day for over a week now, and it’s kind of exhausting!
