I have two kids and they are very picky with their milk. I used to worry they weren't getting enough, but the doc told me that if they eat yogurt and cheese (other dairy products) then it's fine. But like you I still wanted them to drink milk.
My kids drank their milk better if I added chocolate to it. I use the nesquick powder because I don't have to add a lot. I would also make them hot chocolate with milk. Well it wasn't necessarily hot, but warm. It helped them drink their milk and their doc said that the chocolate wouldn't hurt anything.
Good luck with this. Sometimes too, they'll associate that drinking milk means it needs to be in a bottle. So if it was recent that your daughter came off the bottle, that may be the reason she doesn't drink it as much.
