Nasal congestion in infants with colds is mostly caused by viral infections and is usually treated with general therapy, such as clearing nasal secretions and applying hot compresses to the nose, etc., with medical treatment and medication if necessary. Nasal congestion is very common in infants after a cold, mostly due to the increase in nasal secretions in infants after a cold. Parents can use a clean cotton swab to gently roll out the nasal secretions. If the secretion has dried up, dip the cotton swab in saline to soften it before removing it. Apply hot compresses to the root of the baby’s nose to relieve nasal congestion, etc. Since infant cold is a self-limiting disease, if there are only symptoms of nasal congestion, there is usually no need for medication, and daily attention should be paid to adding or subtracting clothing for infants with the change of ambient temperature, and drinking more water. If there are other symptoms or if the symptoms are more serious, it is necessary to consult a doctor in time for medication.
