K.C.
I know this may sound crazy to you, but take her to a Chiropractor. I have 3 friends and their children always used to get ear infections. Since they have been taking them to the Chiro they never had one again! It is safe and painless. The one friend even had tubes put in her son's ears two times and they fell out both times.
My son had fluid built up in his ear and his Pediatrician prescribed an antibiotic. I took him to the Chiro (he goes regularly anyway) and it cleared up without giving him the medicine.
