Hi J.,
I can certainly relate to your daughter's ear infections. It's been many years now, but my now 21 year old son (2nd child) started ear infections when he was six months old.
His first ear infection caused a rupture in his middle ear. With frequent infections, his pediatrician placed him on anti-biotics, but he soon became immuned to them.
Desperate for help...and an end to all the infections, my son developed Psedemonus (sp?), a very serious ear infection. Our options from his ENT was ear drops...which had a small percentage rate of causing permanent hearing loss, or hospitalization.
I was willing to take any chance for any hearing loss, so my husband and I elected to put him in the hospital to undergo anti-biotic treatement throught an IV. After a few days in the hospital, we were informed only one of the three anti-biotics were fighting the infection. We were very limited because our son was alergic to Ceclor...or anything in the Ceclor family.
Fortunate, we were blessed, and in a weeks' stay, our son's infection did clear up. We also were advised to place tubes in his ears, which we did three times. Our ENT simply told us, he will "grow out of it".
About two years later, we took our son for his last ENT visit. He obtained a clean bill of health concerning his ears, and we were even told he could go swimming without ear plugs!
My advice to you would be...take your daughter to an ENT, if you haven't already. They are much more experience in this area, and can advise you on what is best for your daughter.
Blessings!
Judy
