Thanks everyone. I've been to this doctor a few years ago. He sent me off for allergy testing and it came back that I was highly allergic to dustmite and mould. The allergist did a simple food test and I came back ok on that side of things. My normal GP has told me to give up bfing so that I can take antihistamines, but i'd rather get to the source of the issue instead of mask it. Therefore I am going back to this other gp who is a little left of centre in his practices. In any case if they do recommend I give up bfing to treat the allergies I will persist until DD is 12 months and then start treatment.
