Refused milk

My 11 month baby does not want milk anymore . I usually prepared 150ml but she will drink less only ard 40ml . She does not eat much also . Drink water also not alot . Nothing is wrong with her , she still seem happy and active . She started to dont want milk when 9 months old. She drinks fm anyway . Now getting worst. Any mummy experience this?#pleasehelp #advicepls #bottlefeed
