I have heard different things about the elimination diet. People have told me that only proteins in the blood can be transferred into the breastmilk. Milk isnt made from our stomach contents. Therefore milk is a probable cause, but something like...tomatoes or citrus wouldn't be a cause because they don't become proteins in the blood. Have you heard this before? I stopped dairy when DS was about 2 weeks old, and then started cheating recently. So that could be it. I've got serious about it again.
