My LO has had a rash on her face and neck for a few weeks now, she doesn't seem bothered by it at all. The doctor has recently told me to double rinse my clothes as it could be from the detergent (and yes I use baby friendly detergent). I have since started doing that and I thought it was clearing up a bit. Now I've actually noticed it gets worse after she nurses and it's definitely not from friction or the clothes since it's all over both cheeks. I know a lot of people say dairy allergy is common but I don't eat dairy every day. Could she possibly be allergic to oatmeal? That is one thing I definitely eat every day. Any advice would be appreciated!  tIA
