Prevent a Cold Leading to Ear Infection

Hi, My 8 month old daughter is running an ear infection now. She had one last month as well. I am just wondering if there are any precautions that can be taken when they start a cold, so that it does not become an ear infection? I usually do humidifier, saline drops , steam inhalation etc to help with the cold. Thanks, M.
