Hi everyone baby was born at 36 +3 I'm using Dr brown bottle with the size 1 teat but she seems to be struggling with the teat, I think it's the shape , I am keen to use a good anti colic bottle as my fourth child had horrendous colic and nothing helped , anyway would you say the mam bottles are good for preventing colic as I'm trying to find a good anti colic bottle, I used mam on my fourth child and it didn't really do anything so I'm unsure if it was just him or the bottles .
