Girls, please tell me what kind of rash it is? Is it an allergic dermatitis? We had it at 4 months old only on the face, we treated it with emolient cream and then it went away. Now this, first there were colorless pimples that were only noticeable when touched and didn't bother us, then they started itching and became like this rash. The doctor said allergy and immunity, I'm going to see another one, can you tell me if anyone has experienced something similar?
