My 4 week old DS2 is very unsettled generally. I have been told by hv and GP that he probably has reflux and colic so we have tried Gaviscon which made the problem worse. DS2 is ebf and appears to latch on ok but then often pulls off again frequently during feeding and appears very uncomfortable and squirms constantly. He seems to gulp down lots of air with the milk and I can hear his tummy gurgling all the time. He often feeds for just a few minutes and then falls asleep. When he finishes feeding my nipples are flattened and white at the ends which then returns to normal after a few minutes. He was checked for tongue tie by hv and midwife and both said he was fine but I'm not sure. Any advice?
