My son's ear was red and swollen yesterday, but only at the bottom. By today it was perfectly normal. If you are messing with her ear and looking at it, trying to put cream on it, etc than she's going to start messing with it too. Just leave it alone, and check it when she doesn't know that's what you are doing. Honestly, this doesn't sound like something that warrants a doctor's visit, I would bet it's back to normal in the morning. Antibiotics are over-prescribed, and unless there are real signs of infection or they do bloodwork there is no way I'd give them to my kid based on a reddened ear. Lots of pediatrician's prescribe them to make the parents feel better, not because they are actually indicated.
