I just wanted to share my experience with my daughter and ear tubes and ear infections.
She had constant ear infections and we had tubes put in at 18 months old. Then one of the tubes fell out almost immediately and the ENT doc wanted to put in another tube and take out her adenoids. I then read Spontaneous Healing by Dr. Andrew Weil and his book suggested eliminating dairy and having cranial osteopathy done.
We cut way back on the dairy and were lucky enough to find a pediatrician (we lived in Oklahoma at the time) who did cranial osteopathy. It cleared up her ear infections and she has not had another since and she hasn't had to do anymore osteopathy (which is totally painless, I would distract her with a book).
You can find practitioners on this website - http://www.cranialacademy.org/
If you can't find a cranial osteopathic practitioner, then craniosacral therapy is very similar and you can find a practitioner through this website - http://www.iahp.com/pages/search/index.php
Good luck with everything!
