Two-year-old babies with constant runny nose are clinically diagnosed to have chronic rhinitis and sinusitis, and should be seen and examined in pediatric outpatient clinics or pediatric otorhinolaryngology clinics as soon as possible. Allergen testing is needed, and the symptoms of runny nose can be cured only by avoiding repeated contact, intake and stimulation of allergens. Necessary treatment can also be carried out, such as cleaning nasal secretions with saline nasal spray when there is a lot of runny nose, or topical spray treatment with spray-type drugs that reduce inflammatory reactions in the nasal cavity. During infections, especially during weather changes, babies with chronic rhinitis and sinusitis are prone to secondary viral or bacterial infections. If there is a bacterial infection based on the need for anti-infective treatment, commonly used amoxicillin, cefaclor, etc.
