When my son was 4, he had a recurring ear infection. Antibiotics did not help, and I was very frustrated. It seemed like a vicious cycle. Finally, I stopped taking him to a doctor (and stopped the antibiotic round). Instead, I would put a small piece of cotton ball dipped into garlic oil or mullein oil into his ear before bed time. Both are supposed to work well for this. (Mullein is an old native-American remedy for ear ache.) I also gave him high doses of vitamin C, garlic, echinacea, and golden seal (in liquid) mixed with his juice several times a day. Once he recovered, the problem did not come back.
