The child's cold and cough are caused by catching a cold and getting angry. When they are weak and angry, milk is a high-calorie drink, which is not suitable for drinking. The child has a fever, and the parents are anxious. They can't wait for their children to get better at once. The mood is understandable, but unrealistic. If the child has a cold and fever, he will not take medicine if he can use it externally. If he can take medicine, he won't have an injection. If he can get an injection, he won't have an intravenous drip. The specific method is as follows: first, wipe the child's chest and back with a hot towel to wipe off the cold on the child. This method is the best, it doesn't hurt the body, and it can also improve the physique. Secondly, take medicine, and buy appropriate cold medicine according to the symptoms. Finally, injection and intravenous drip, although effective, have the disadvantage of increasing third-party infection and doing great harm to blood vessels.

It is suggested to lead children to do outdoor sports on weekends or in leisure time to enhance their resistance and improve their immunity.
