I am a new hubber, but as i was researching this subject I came across your request.
I'm not sure after all this time if you are still seeking an answer, but I hope this helps.
The Seagate Company www.seagate.com has a product that has helped immensely with my son's ear infections. He is one year old.
Danny kept getting ear infection after ear infection until one day, our doctor prescribed Nystatin (prescription antifungal) for the thrush in his mouth.
I then started him on Seagate's olive leaf extract ear drop formula (for infants and adults). No problems since. (Praise God!)
It's only about $10 per bottle, lasts a very long time. They did studies to indicate that olive leaf extract is a potent and safe anti-microbial known to kill fungi, viri, bacteria and parasites.
You can't go wrong trying this product! Blessings, David
