DD 6.5 months had some salmon yesterday and almost instantly developed some red blotchy patches around her mouth. I dabbed a little on her arm and she got a red blotch there too. Does this look like a allergic reaction? Today she's covered in a rash (which isn't out of the ordinary actually because it's linked to her eczema) however not sure if it's linked to the fish incident or that she's had a fair bit of dairy today. Just wondering if anyone else has encountered this?
