consider taking her to a chiropractor. my son had ear infections every month (sometimes a couple of times a month) from the time he was 6 mo to a year. he was even taking anitbotics daily to prevent them and would still end up getting them. he got to the point where the strong anitbotics didn't work. they to suggested tubes. my grandmother told me to try a chiropractor first before doing the surgery since the tubes doesn't prevent the infection only drians the infection into the stomach and he may have to have it done several times as he grows or they fall out to early.
after talking to the chiropractor to me it made sense that the neck is out of place and pinching the drain tubes in the ears. with learning to sit up, crawl, climb and walk and all the falls and tumbles they take while learning moves the vertabrae's out of place. after taking him to the chiropractor only a couple of times he didn't have another ear infection for 8 years... he got that one after swimming alot one summer. just another suggestion before doing the surgery and putting the little one out.
good luck with your choice and little one, i know how its no fun to have them in pain!
