2 months old baby cold and nasal congestion is a common symptom, because the infant respiratory system is immature, the nasal cavity is relatively short and small, the nasal mucosa is tender and rich in blood vessels. After being stimulated by the outside world, the nasal mucosa is easily congested and swollen, and the secretions in the nasal cavity increase significantly, often manifesting as nasal congestion. You can use a few drops of sesame oil to soften the nasal discharge, and then carefully dig it out. It is best to use a humidifier or place a few pots of water in the house to increase the humidity of the air in the room, and to open the windows frequently to ensure the flow of fresh air. You can also use a hot towel on the root of the nose, or use furosemide drops to take a drop. Padding the baby’s head and shoulders while breastfeeding can also cure nasal congestion. If the above symptoms are uncomfortable or the nasal congestion is not reduced, you should go to the hospital for treatment.
