Hey T.,
I had the EXACT same thing with my daughter for the first year of her life. She had an ear infection at least once a month. Then She had one so bad that the infection made her vomit and have diarrhea (sp?) and she was in the hospial for dehydration. The Dr. had her on high powered antibiotics and it didn't work, the infection kept getting worse until the whole hospital/dehydration thing. Then they put her on IV antibiotics for 3 days and that finally knocked it out. Anyway, I ended up taking her to a chiropractor when she was a little past 1 to have her checked out, (The whole family was getting a check-up) and the first thing he said when he was examining her neck was "Has she had a lot of ear infections?" I was like "YES! How in the world did you know that? They want to do surgery, tubes, and preventive anti-biotics." He said "Well, the part of her spine where the nerves go from the spinal cord to her ears, is badly misaligned, most likely from the natural trauma of birth, but it could be from a fall or something else, but at any rate, I would be shocked if she WASN'T having ear infections."
SO, I had him adjust her 3 times a week for a few months, she LOVED it and would ask for it when she needed it again, and the results were MIRACULOUS to say the least. She went from one or more ear infections a month to NEVER HAVING ONE AGAIN!!! She is almost 4 1/2 now and still free from ear infections. I am SO glad I found chiropractic and it cured her ear infections without surgery!
I don't know what the answer is for you, only you will know that, and I am not saying this should have been the answer for anyone else, but it worked beautifully for me and it was painless for her. I highly recommend you look into it, and your insurance may even cover it.
Good luck, and please let us know how it turns out!
