If it is dry secretion, you can apply some ointment, or eye ointment, or dip a cotton swab in water and drop it in the baby’s nostrils, make sure it is the right amount to make it loose and soft, then use a cotton swab to pluck it out, or let the baby cry for a while and wait for the tears to soak the nasal scabs and make them soft, then gently tug them out by hand. Secondly, you can use a warm towel on the nose, after the nasal mucosa is contracted by heat, the nasal cavity will be more open, and the sticky nasal mucus will be easier to hydrate and flow out, which can relieve nasal congestion, you must keep gentle movements when applying heat.
