My five week old baby has had problems feeding ( formula). She was starting a feed then stopping screaming and arching her back in pain kicking and resenting the bottle despite showing the feeding cues of a hungry baby so she could only feed smal amounts. This happens every feed. Health visitor told me she is "fussy" and it's just colic. I agree she has colic in the afternoon she often does inconsolable crying between 5-7pm but this is different and all day.  Anti colic bottles and infracol /dentinox made no difference . She's been checked for tongue tie and thrush and is ok. I took her to the gp they said for us to try colief, since we started that she is taking bigger feeds but she is still reacting badly and appears to be in pain after feeding. She burps ok and stools are Normal. It's breaking my heart and feeding her is becoming a bad experience  for both of us. Any suggestions ?????
