M.T.
My first suggestion would be to stop giving her milk in the bottle. For a few weeks, only give water in the bottle, and if she wants milk she can drink it in a different format (cup, straw, etc.) My son is 3 days younger than your daughter and he has been bottle broken since about 10 months old. As soon as his front teeth were fully in I took away the bottle and he jumped to straws with no problem. At 15 months he is already on cups.
She may be young, but even transitioning to cups from straws, I explained to my son 'big boys use cups without straws' and he understands. I help hold his glass while drinking, and then put out of reach while he eats. He lets me know when he wants a drink and the process repeats itself. You could do the same thing by taking away the bottle.
If using it only at night and nap, it is more of a comfort issue than anything. I don't know if you want to introduce a passi this late in the stage, but try using that instead of the bottle. At 15 months that milk staying on her teeth while she sleeps is going to start doing damage a lot sooner than you think.
