M.T.
G., when I did this with my kids, I would fill the bottle with water. If they are really thristy then they will drink it, if it's a habit/comfort thing, they will most likely give it up in about a week. I also told them that big girls drink milk from a cup and it worked for all 4 of mine. If her waking & crying at night is too much for you, then I suggest that you comfort her and hand her the bottle (with water). If that doesn't work, then take her to the kicthen and put a little milk in a sippy cup and let her have it. Once she is done, tell her it's bedtime, let her put the cup in the sink and off you go. It may take a week of doing this (it'llbe hard on you) but if you stuck to it, then it should work. Good luck
