H.M.
At the first signs of an ear infection, I just heat a couple whole garlic cloves in some extra-virgin olive oil. I allow it to cool to body temp and then place a couple of drops in my daughter's ears every couple of hours. It has worked with my 3 girls every time. You might want to give it a try. As the first person said, I think they also sell ready-made drops at some health-food stores. Hope this helps.
