Hi! My 8 month old has been running a low fever (99-101.4) off and on for the last 4 or 5 days. She is playing and happy and is no longer running a fever, but this morning she developed a rash on her temple, forehead, left eyelid, trunk and lower back. We have a doctors appointment tomorrow afternoon. She seems happy so we are thinking Roseola, but her appetite is not normal so we are wondering if we should go to an ER.
