Tips please!

Please don’t be rude, it’s already hard enough being a mama:) so my two year old is still obsessed with a bottle. We’ve tried every silly cup out there any it’s just something about a bottle she loves, it’s not so much her drinking out of a bottle that bothers me though, because she will drink out of a regular cup at the table and stuff, it’s the CONSTANT want for milk. She wants milk all day every day, the pediatrician has told me that it could cause anemia and other issues if she drinks too much I’ve switched to giving her skim milk and then doing mostly water with the milk to cut back on how much she’s getting, it causes her to not eat food hardly, anytime I make a meal it’s “no I want milk”, and I mean she’s healthy she’s over 45 lbs and her pedi said the weight is from the milk, but I just feel like such a bad mom giving in every time and giving her the milk, it’s especially bad at night time she wants it to go to sleep it’s like she HAS to have it or she throws a fit and I fight with her for hours trying to give her water or even watered down juice, but eventually I have to sleep too, I’m pregnant and just exhausted at the end of the day. Any tips on how to break this and break from the bottle entirely?
