If a newborn baby has coughing symptoms during the month, it can be treated by the following methods: 1. The child needs to be fed warm water regularly, which has a certain alleviating effect on children with mild coughing symptoms. The room also needs to be ventilated regularly, 2-3 times a day, and the humidity in the room needs to be appropriate, usually kept between 50% and 60%, and the temperature should be kept at about 20°C. 2. The mother needs to eat more fresh fruits and vegetables to help the newborn’s cough symptoms improve. 2. If the newborn’s cough symptoms are serious, he or she needs to take medication under the guidance of a doctor, such as pediatric cough syrup or mahogany cough syrup. It is recommended that parents take the affected child to the doctor in a timely manner, as the newborn’s organs are delicate and may lead to adverse consequences if treatment is delayed.
