Hi, my LO is 4 weeks old and from around 2 weeks she has been having constipation which has now turned into yellow diarrhoea with mucus, she has a red ring around her bum and is generally really unsettled for a good period after feeding (she is formula fed) with inconsolable crying. She brings her legs up to her chest, sneezes a lot! I have taken her to the GP who have said it's silent reflux and prescribed infant gaviscon which seems to be making things worse! The GP seems to think it's not CMPA and I feel he is fobbing me off and not taking into account the mucus in her poo. Anyone else had issues with getting a diagnosis? How long did it take?
