I am lost

Definitely need to stop milk at bed time. It can cause decay in teeth. But is it possible she’s too warm or cold? I know if my son is too warm at night he wakes up a lot more so I have a fan in there and I set a timer on it. And he has a sound machine. A

It’s really common for toddlers this age to wake for bottles, but at 18 months it’s usually more about comfort than hunger. Instead of stopping suddenly, try gradually reducing the number or amount of bottles over a few nights (drop one bottle every 3 days), or diluting the milk with water. You can also try settling her without a bottle first and only offering a smaller feed if she doesn’t go back to sleep- you need to break the wake = bottle association. Make sure she’s getting enough food and milk during the day, 3 meals and a few snacks (as well as milk during the day). It might involve some protesting, but with consistency she’ll learn to sleep without needing so many night feeds.
