Corporal punishment is when an adult does something to physically hurt a child as a way to punish them for bad behavior. This might include spanking, hitting, or even shaking a child. It is not a good way to discipline children because it doesn't help them learn the difference between right and wrong and it can hurt them. Many doctors and teachers don't believe it is a good way to discipline children because it can damage their self-esteem and make them scared of adults.
