If you can directly see the obstruction or secretions in the nose, first of all, you can take the baby cotton swab and dip it in some water or baby oil and then go deep into the nostril to take out the secretion. Don't go too deep into the nasal cavity. The mucous membrane in the nasal cavity is very fragile. Don't remove it blindly and cause injury. Gently wipe off the nose and nose. Secondly, apply a warm compress on the nose with a warm towel. After the nasal mucosa shrinks due to heat, the nasal cavity will be smoother, and the sticky nasal mucus will easily hydrate and flow out. Of course, the most convenient and effective way is to use a nasal aspirator. Put the baby on the thigh and flat place, facing the parent, flatten the nasal aspirator, put it in the nostril, and slowly loosen the Nasal aspirator. Shit will be sucked out.
