dd (9 months) had a home made fish pie puree today, and a bit later came up in nettle sting like white spots on her face and this was later replaced by a blotchy red rash (like sunburn) on parts of her body - noticably her cheeks, buttocks and back. I rang NHS, and as she has no fever they thought it was possibly an allergic reaction, and as I have changed nothing else, like washing powder, creams etc, I can only think of the fish. Do you think this is possible, or am I barking up the wrong tree?
