Stuffy nose: Hold a wisp of cotton or tissue in front of nostrils to make sure that some air is coming through. Rarely the nasal passage is completely blocked at birth. Most babies respond to saline nasal spray and suction with bulb. If you put a litle vaseline on tip then the builb goes in easy and seals well for good suction. If congestion persists, then tell doctor.

See below: It could still be a sign of a stuffy nose of a newborn-amendable to upright positioning of the head; saline drops or spray to loosen up dried mucus - and suction. Rarely it could be due to a missed choanal atresia: a narrowing or blockage of the nasal airway by tissue. It is a congenital condition, meaning it is present at birth.Is a narrowing or blockage of the nasal airway by tissue.

Airborne 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 aggressive washing out the nose with saline & suctioning the remainder. Eliminate irritants from babies environment & this will happen less.
