A baby’s cough is similar to an adult’s cough, but because of the poor resistance, children’s coughs are more reactive than adults’. When a child has a cough, it is important to observe the nature of the cough, the presence of complications and systemic symptoms before deciding whether to seek immediate medical attention. In the following cases, children can be observed and not rushed to the hospital: cough and fever but good spirits, mostly cold or tonsillitis; cold, fever and cough followed by cough all the time; cough and sputum but no fever and good spirits; cough that occurs only in the early morning; slight cough when nervous or after exercise. At this time, you can first relieve the symptoms and treat the cough through dietary therapy. For example, steaming garlic water for wind-cold cough, pear and rock sugar and chuanbei water for wind-heat cough, and boiling yam porridge for a long, recurrent cough. If a child suddenly coughs badly and has difficulty breathing, a foreign body may be blocking the airway. Things that are easily swallowed by mistake include peanuts, pencil sets, pills, buttons, coins, candies, etc. It is fine if they are found immediately and first aid measures are taken to remove them, but it is very dangerous if a foreign body is never found stuck in the airway. If it is accompanied by high fever, coughing, wheezing and difficulty in breathing, it needs to be sent to the hospital immediately for emergency treatment. In general, it is not advisable to interfere too much with the cough, but if the child’s cough is affecting the quality of life, cough medicine or even nebulized inhalation can be used to help relieve the cough if the cause is clear.
