? irritants? The first months are troubled by narrow nasal passages & exposure to dust, fragrences & other irritants are assumed to be allergies. 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 baby's environment & this will happen less.
NASAL ALLERGIES. By taking out allergens like smoking at home, animals and dust. Suction the nose with saline and bulb syringe.
