While I believe that chiropractors can do a wonderful job of alleviating muscle and joint pain associated with all sorts of injuries/conditions related to the back, I do NOT believe that one should take their children, much less infant, to one. Despite what information you may receive from people on here that swear by its healing capabilities, much of the "healing" can be attributed to the placebo effect, or the BELIFE that the patient is cured. I am not the only one that feels this way, and in the larger medical community, my beliefs concerning chiropractic care are very commonly held and, more importantly, scientifically backed.
A chiropractor is not a doctor. They do not attend medical school (they do attend chiropractic school) or earn a medical degree, and I would much rather a doctor do the poking around when it comes to something as important as my childs ears. Ear infections happen: and twice in a two month period is "normal" in an infant, especially if an upper respiratory issue (a cold, the flu, a cough, runny nose, post nasal drip, anything like that) is present. Despite what people may claim, a chiropractor cannot "cure" anything (nasal allergies, food allergies, lactose intolerance, anxiety, mental illness,etc) but do help diminish, alleviate, or and some cases "cure" (through continued care) back/neck/shoulder/joint pain. Does it make logical sense that an adjustment of the neck or back can cure any of the aforementioned conditions? Not in my book.
I have gone to chiropractors for neck and back issues at several points in my life, and my mother has managed a chiropractic office for 25 years. Call the chiropractor that she works for "new age" but he agrees that any chiropractor that claims to be able to cure things not related to the spine is not reputable. It does great things for my back, but I would be really scared to take my kid to one, much less one I dont know, if not recommended to visit by the pediatrician.
If you are really concerned about the ear infections, ask for a referral to an ear, nose, and throat specialist who is MEDICALLY TRAINED to work specifically with your childs ear infection issues. You wouldn't go to a neurologist to treat a broken foot, why would you take your child to someone who is a back specialist and NOT trained to care for the ears?
