You can take the hard step of just not giving it to her. It will make for a few hard nights but after that she will be done with the bottle. My friend told her little one it was lost and another friend tied balloons to a bottle and let her daughter send it to heaven to the baby angels and then replaced it with a "big girl bed buddy" of the girl's choice. She bought it a few days before but would not let the baby take it to bed until she agreed to send her bottle to the baby angels. (Hint, go to a parking lot where there are not a lot of trees, if the bottle gets stuck in the tree it makes it hard to remind her that she sent it to the baby angels)
Good luck,
