ah! my DS might be similar. also had intolerances/sensitivities to foods since birth. i know dairy is a trigger (gut issues when he was little, skin issues now - but maybe gut issues too?), but there might be something else too. local dr is hopeless, and has said he won't refer til DS is 2. i am not sure medicine is the answer, maybe a naturopath or dietician but not sure how to go about it.
