Don't get your hopes set on allergy testing. I took DS for that and was asked what he was allergic to. I didn't know - that was why he was at the hospital for the tests (wasting our entire day). Oh no, I have to say what he's allergic to and then they test for that. How stupid is that? They tested for cow milk, when I said he's intolerant not allergic, and I was right, he's not allergic. So why not test for things I don't know about? Grrr. (Yup, still a bit annoyed about that!)

I did say "how about trying X, Y and Z" but no, they wouldn't because I didn't know if he were allergic or not.
