If children develop a cough due to a cold, like occasional mild coughing, slight nasal congestion, and runny nose, without obvious fever, and they maintain a good spirit and appetite, parents do not need to worry too much. Let the children rest appropriately, drink more warm water, and eat a light, easily digestible, and nutritious diet. A common viral cold generally has a certain self-healing capability. However, if the cough is more severe with noticeable phlegm, a significant decline in spirits, or if high fever occurs, it is then essential to visit a hospital promptly for doctors to treat the child based on their condition. Typically, children should not take cold medicines that are meant for adults, as these can have significant side effects on children. A usual viral cold infection tends to be self-limiting, so parents should closely monitor the progress of the illness, and seek medical attention promptly if the condition worsens.
