I know this is slightly off-topic, but...
I know a few toddlers who have never drunk milk once the bottle was taken away. That said, these kids are also healthy and happy because they get their dairy nutrients from yogurt, cheese, yogurt smoothies, etc. My niece won't drink milk anymore, so her parents buy pre-made yogurt smoothies, dilute them half-and-half with milk, and then she drinks them up. Here (I have 3 little ones), I make shakes in the blender with milk, yogurt, frozen fruit, and a little honey.
Also, kids her age usually like to drink with a straw, maybe try that as well.
Personally, I see nothing wrong with the bottle at bedtime as a comfort, but maybe naptime can be made into more of a "big girl" time with a smoothie and a straw before going to her bed.
Good luck to you and your little girl!
