OK--so you were told to try it though. I have only tried me eating dairy, so far haven't let DS eat anything. And his reaction wasn't severe (at least, I don't think it would be classified as so--he never had blood in his stools, just green, slightly runny poops and then eventually, started to get a rash on his chin (that was DD's tell-tale sign).
I think I will go ahead and try a little and see what happens.
