There is def. a push from doctors and dentists to ditch the bottle after the age of one when possible so that there is no effect on the teeth and their position, etc. Also, if you are offering milk in a bottle before nap and bed, be sure to brush or wipe the residue off of the teeth before sleeping. The milk residue turns to sugar as it breaks down and can rot the teeth and cause decay and cavities, etc.
That said, you can try to offer the milk in sippy cups instead and offer during meals rather than before sleeping times. If your LO still enjoys having a bottle or drink before sleeping you can try to switch to water so at least the risk of tooth decay is gone. For a time my DD was taking a sippy cup into her crib with her with water in it so she could have a sip whenever she wanted on her own.
So, essentially, yes, if she WILL take liquids from a sippy, I would try to move all her liquids, including milk to sippy cups and try to start weaning off of having milk right before sleep times. I would offer milk or water with meals and limit juice.
