Waking throughout night- help!

My daughter has been sleeping through the night since she was 2 months old. Now she’s 13 months and for the past few weeks she wakes up 2-3 times a night to drink (either water or milk, she doesn’t care). Last night she wouldn’t go back down until she had TWO 8oz bottles! Then I have to change her multiple times throughout the night otherwise she wakes up SOAKED. Is this normal?? A phase? I just want to sleep again 😔
