In the case of a newborn baby with cough and nasal congestion, which is relatively mild, it is recommended not to give any medicine to the newborn baby for the time being, and you can continue breastfeeding because breast milk itself is rich in immunoglobulins and natural antibacterial factors, and also contains a lot of water, which can improve the baby’s immunity and is very helpful in fighting pathogens. You can locally clear the nasal secretions to keep the breathing open. If the symptoms are relatively serious, then consider taking medication. It is recommended to visit the neonatology department of a regular hospital to determine the cause of cough and nasal congestion according to the doctor’s examination and the corresponding laboratory tests. After the cause is clearly identified, appropriate treatment should be given. Parents should not take antibiotics on their own to avoid allergies and over-treatment of newborns.
