Is there a way to prevent ear infections in a baby after a cold?

No smoke exposure: Ear infections are common in children following a cold. Due to the nasal congestion, the eustachian tube (connects the nose to the ear) gets clogged up, allowing fluid and infection to form beind the ear drum. The only thing you can control is smoke exposure. It leads to chronic nasal congestion which can lead to ear infections.

Some basic ideas: Babies are prone to ear infection because they have tiny plumbing that drains mucous made inside the ear to the throat. That drain (eustacian tube) can be invaded by throat germs if it is not flowing. Exposure to cigarette smoke, perfumes, wood burning stoves, candles, cleaning fumes, etc. All increase chances the baby will have ear infections. Avoiding these helps, but growth is the main solution.
