PP, this might sound silly, but when you say she's off all dairy, but is on formula........what sort of formula is she having? Does she have a known reaction to dairy products? It sounds like quite a bad rash, and is obviously distressing you and your DD. I personally would be going back to the GP, and if they can't give you any definitive answers, then I would be asking for a derm or paed referral. It sounds like it's being going on for some time, surely someone can help you out with it. You could specualte for ages about all the things it may or may not be, you really need someone in the know to have a proper look at it. I hope it gets sorted out soon for you, it must be so awful for you to see your baby like that
