Phillips avent bottle

Hi mummies, ftm here. Those thats using phillips avent bottle(not the anti colic one), at which month did your baby need to start using the 260ml bottle ? My baby now drinks 120ml and the 125ml is already like swee swee and the next bigger bottle of avent is so big and tall (260ml). Just wondering how to bring out cause takes up so much space and like weird baby still small but bottle so big (‘: #firsttimemom
