The nose of a baby of about half a month is often blocked. Neither going outside nor coming into contact with someone who has a cold, yet the nose is still blocked. Sometimes nasal wax accumulates, but even if it is carefully removed, the nose still does not pass, and it gradually worsens to the extent that it reaches the point of not being able to take milk in about 3-4 weeks. If you go to the doctor, you will be told that it is a cold and given some medicine; if you go to the ENT department, you will be given medicine for your nose again. However, no matter what you do, it won’t work. If you go to the doctor again and say that you are not cured, this time the doctor will say, “Then give an injection. Even after asking the doctor to give the injection, there is still no change. Most of the babies with stuffy nose have floating skin on their eyebrows and acne-like growths on their faces. If you know that the father of a baby with nasal congestion also had nasal congestion as a baby, you will understand that nasal congestion is an idiosyncratic condition. It is true that babies with nasal congestion may have difficulty feeding because of nasal congestion. However, it does not reach the level of complete inability to take milk. Although it takes some effort, you can still breastfeed. The real painful period is only about 1 week, so don’t rush. In terms of season, it is more common in winter. On days when there is an unusually dry climate, hanging a wet towel in front of the stove or the heater will reduce the dryness of the air. Overheating of the room is also associated with nasal congestion. When the weather is good, frequent exposure of infants to outdoor air will open up the nasal passages. It is not good to keep them in the room for fear of catching a cold, or to keep the room temperature hot. Do not give nasal laxatives used by adults to infants. Some people use sterilized cotton swabs soaked with olive oil and put them in the baby’s nasal cavity to make the baby sneeze and expel nasal dirt, but it does not work if the nasal congestion is caused by swelling of the mucous membrane. Grandmothers often use their mouths to suck out secretions from the baby’s de nostrils, which does prevent blockage at the nostrils. In general, it is better to let the baby inhale the outdoor air as much as possible and wait for natural healing. After 1 month of life, the nasal congestion will become very mild and soon, it will be cured.
