Mailbag! Ear Infections and why they happen

Hear how Dr. Sean responds to this grandma with a 19 month old grandson who got his first ear infection last week. This little guy sees a chiropractor twice a week, has an incredibly healthy diet (mostly vegan, salmon now and then) and is not in day care. Today he woke up with a fewer and is messing with his ear.

Grandma has 2 questions: 

Does he need antibiotic and why doesn’t everything my daughter is doing not prevent ear infections?
