C.M.
Please try chiropractic. It is safe, gentle, and effective for children and ear infections. I myself battled with ear infections as a kid and as as adult. Both of my eardrums have perforated twice. Since I have started seeing a chiropractor all of my ear problems have gone away.
I have been taking my children, ages 5 and 4, to the chiro once a month since they were infants. I also get them in for an adjustment when they come down with a cold or congestion. Neither of my girls have ever had an ear infection. Also, neither of them have ever been on an antibiotic.
I watch a 3yo girl M-F who got tubes about 8 months ago - she has still had 3 infections with the tubes and now it takes two rounds of Omnicef to clear it up. I have suggested Chiro to them many times but they have still not tried it. A chiropractic adjustment will properly align the eustation (sp?) tube so that it can drain.
Please try it - it really is safe, gentle, and effective. My girls actually enjoy going.
