He doesn't seem to be in any gas related pain though. He is a bit under weight according to the doctors but doesn't look sickly thin, kwim? I mentioned the lactose thing to the mom yesterday when I was telling her about his poor little bum but she doesn't think it is. She thinks it's raisins and grapes. I'm going to talk to her about it a bit more today and see if maybe I can get them to consider either some testing or try (as an experiment) cutting out dairy for a week or 2 and see what happens. If there is no improvement with doing that, then try cutting out glucose and see what happens.
