YES! Big HUGE YES! to chiropractic. We've been seeing a chiropractor for many years now. My son, who is now 3, has been seeing her since he was 2 days old. Adjustments absolutely help at getting rid of fluid in the ears.
Another thing that you can use is Pure Therapeutic Grade Essential Oils, like Young Living brand. My son ended up with double ear infections when he was 2. He is such a trooper I had no idea that he had them at all until he spiked a fever one evening and wouldn't/couldn't settle to go to sleep. I thought he was teething and basically laid with him all night comforting him back to sleep many times. In the morning he was pulling at his ears. I looked in his ear canals and was SHOCKED to see that they were both filled with pus. YIKES!! We immediately started using the blend Purification and the single oil Helichrysum on and around his ears. After three days, he was much better but I wanted to be sure, so I took him to the doctor. She looked in his ears twice, asked me again, when he'd had pus filled ear canals and I told her again 3 days prior. She said, "You did a miracle. He has no ear infections at all."
Essential Oils are amazing and completely natural medicine from plants!!
Something else to consider....one reason ears get infected can be due to blocked Eustachian tubes. These are where they put "tubes" to make a clear pathway for drainage. Many things can cause them to get blocked, but often it is due to inflammation. Have you tried eliminating foods like dairy, sugar, wheat, gluten from the diet? All of these can cause inflammation.
Hope this helps! If you want more information about the essential oils, please let me know and I can assist you!
