My son has been diagnosed with CMA and prescribed Neocate milk. Great as the blood in his stools has disappeared but in its place is constipation, acid reflux (he drinks until a gargle sound - the acid- causes pain to which he arches his back, cries etc), and colic. Is there anything I can try to help any of these?! As it’s effecting how much he drinks, sometimes only taking 1.5oz. Anyone experienced similar? I’m trying water for the constipation.
