Hi, so my 5 year old has been off dairy since June 2022 due to dairy intolerance and we are now trying the dairy ladder. I gave him 1 biscuit a week ago and 2 days later he had diarrhea and vomiting (I assumed a bug). Then I tried half a biscuit 5 days ago and yesterday he had a whole one again but 12 hours later he has been sick. Could it be the dairy intolerance or something else? (He has never been sick from dairy before) thanks
