When a newborn baby has a cold, it is mainly because the baby’s immunity is relatively poor and the defense function of its respiratory system is not perfected, so it is easy to be invaded by outside viruses, bacteria and other pathogens. For babies with symptoms of nasal congestion, runny nose and sneezing, you can use a hot towel to apply hot compresses to the infant’s fontanel without burning the baby’s skin, which can relieve the symptoms. If a high fever persists, you can give your baby a hot bath, still paying attention to keeping warm and avoiding getting cold. You can use warm water dipped in a towel to wipe the baby’s neck, armpits and groin to dissipate heat and cool down. If it is caused by bacterial infection, you can choose antibiotics such as penicillin.
