7 months old baby not drinking milk

Hi parents, has anyone faced this before? My baby drinks 120-150ml every feed but this week, she starts to “dislike” drinking! She eats oatmeal cereal and fruit purée. Could that be the cause that she now prefers solid food? We use the leftover milk to make cereal for her but we can’t be doing it after each feed right? Is this a phase? Please share your experience as I’m a FTM😮‍💨
