Good night, my little girl! It's been almost a week of diarrhea, but without fever for a day in the beginning, three times at least, then it became frequent! ??‍♀️ Since yesterday she has had a fever, cough, probably flu ? now she is constantly having a fever and diarrhea still. I don't know what to do? I'm exhausted, my constant diarrhea ?
