11 month old still waking for bottle!

Hi! So....I'm new here...! But looking for some help/advice! 

11 month old baby girl is still waking 2 to 3 times a night for a bottle and has done since about 6 months old, no matter what I do or try I just can't get her to drop it...or at least one of them 😩.

The lack of sleep is really starting to take its toll, and I'm desperate for any advice anyone can give me

Thanks
