Dairy allergy and reflux

Hi all,

I’m wondering anyone can give me any advice / information. My son was born two weeks early via c-section. He is now 5months old. From around 4 weeks I was told he had CMPA. I tried for 4 weeks to cut diary out of my diet as I was breast feeding - however it didn’t work and he is now on neocate. Before we moved him onto the diary free formula his nappies were really watery and mucus filled with spots of blood. He would poop after every feed and more. Once moving onto the diary free forumla he stopped getting runny nappies and instead became constipated - going to rhe toilet every 4/5 days and it was difficult for him. Note he also didn’t stop being sick and would even spew and choke through the night , when I returned to the paediatrician They said he had silent reflux and they put him on carobel ( which stopped the sickness but he began having watery nappies again) so they have put him on Zantac. The Zantac seems to have stopped his reflux discomfort although he is still sick often ( and it smells vinegary and hot) he also still only poops every 3 days and when he does his nappies are like mucusy and clay like looking ( sorry for the poop chat)

Anyway my question is - has anyone else had diary allergy and reflux together ? Does his bowel movements sound normal? Should he still be being sick? He just seems in quite a lot of discomfort all the time with his tummy. The doctors tell me maybe he is just colicky But I’m not totally convinced.

Any help appreciated
