we have a baby who cries a lot some times for no apparent reason and has lots of trouble sleeping( seems to fight it) feels uncomfortable she also fretful and fussy during and aft feeds sometimes... Took her to the docs who prescribed gavisgon ( baby doesn't posset a great deal) and said it may be a build up of acid after checking her put physically.... She doesn't seem uncomfortable at times when she is digesting so may be the case and have heard that silent reflux is more to do with build up of acid coming up rather than milk... Has anyone else experienced silent reflux?
