From 1 they only need 12-14oz of dairy to get their needs met and too much milk can actually stop them eating as it fills them up. The dairy in food counts towards their intake, it doesn't have to be liquid milk, so if you reduce the milk offer dairy in food as well. They won't starve themselves, all you need to do is offer a varied diet, she is in charge of how much she eats.
We swapped my DD's morning bottle to a sippy cup of milk as a mid morning snack around 13 months because she wasn't eating breakfast. We swapped the bedtime bottle into a sippy cup around 18 months and then after a couple of months she stopped drinking so much so we stopped offering and she wasn't bothered at all. If she asked I gave her some but she just wasn't interested. My DS had a bedtime bottle until 2.5 and we stopped it when he had a bad cough one time as it was making him sick, once it stopped we didn't give it back. Bed time milk really varies, some people stop it, some carry it on. Just remember to brush teeth after the bottle/ cup of milk and then sleep!
HTH!
