How to deal with frequent nasal congestion in infants?

Patient's question:

Patient Age: Born 45 days
Condition Description: The infant frequently experiences nasal congestion, which can be relieved by applying sesame oil drops. It is unknown whether this is harmful to the infant.
Previous Treatment and Effect: No treatment has been administered, only sesame oil drops are used to alleviate the symptoms.
Desired Help: To relieve the infant's nasal congestion.

Doctor's answer:

1 If the blockage is caused by nasal secretions, you can gently roll out the secretions with a cotton swab. If the secretions are dry, apply some ointment or eye ointment first, or use a cotton swab dipped in water and drop it into the baby's nostril. Make sure to use a moderate amount so that it becomes soft and no longer sticks to the mucous membrane, then use the cotton swab to remove it. Alternatively, let the baby cry for a while until the tears moisten the crust, making it soft, then gently pull the crust out with your hand.
2 Apply a warm, damp towel to the nose. When the nasal mucosa contracts due to the heat, the nasal passage will become more open, and thick mucus will be easier to liquefy and flow out, relieving the stuffiness. Be sure to be gentle when applying the warm compress.
3 Mothers can try changing the baby's position: lie on the right side if the left nose is blocked, and on the left side if the right nose is blocked, which can help alleviate the stuffiness.
4 Nasal acupressure: For older children, sit upright (infants should lie flat). Use your thumb and index finger to massage the sides of the nose from top to bottom for 3 minutes, then gently press the Yingshi acupoint (sides of the nose) for 1 minute. When a warm sensation is felt in the nose, breathing will improve. Repeat every 2–3 hours to effectively relieve stuffiness.
5 When an infant has a stuffy nose and cries incessantly, holding the baby upright can help reduce the stuffiness and make it easier for the baby to fall asleep.
6 If nasal congestion affects the child's sleep, prop the head up at a 30-degree angle to alleviate the symptoms.
7 Pay attention to indoor ventilation and try to maintain the room temperature between 24–26°C and humidity between 60–70%. In cold weather, use an air conditioner or heater to adjust the temperature, which can help relieve the child's stuffiness and runny nose.
