My 2month old baby has a terrible flue and his nose is blocked and he also coughs a lot. but his temperature is fine. how best can you help?

?irritants?: The first months are troubled by narrow nasal passages & exposure to dust, fragrences, smoke & other irritants.Baby tries to flush these out of the nose with mucous but this often ends as congestion & produces rattling with breathing. The best rx is washing out the nose with saline & suctioning the remainder. Eliminate irritants from babies environment & this will happen less.
