Newborn nasal congestion occurs due to the incomplete development of the respiratory system, narrow nasal passages, and the rich vascular network of the nasal mucosa, which is easily stimulated and causes congestion and swelling. Adjusting the indoor temperature and humidity, regular ventilation, and increasing the flow of fresh air can help. Compression of the root of the nose or fontanelle before bedtime can alleviate congestion. Severe cases should be handled under a doctor’s guidance.
