No one deserves to be abused. No one. Children get the
idea that they are bad and deserve to be punished. If a
child’s behavior is wrong,  the child may  need discipline.
Screaming, hitting with other than the palm of the hand,
kicking, biting, pouring boiling water over the child, locking
the child in a closet, etc. are forms of abuse—not discipline.
I don' t recommend hitting a child. The adult swing can cause
major physical damage to a child. An adult hitting a child tells the
child that hitting is okay, especially if the hitter is bigger.
Appropriate discipline  varies with the age and mental
development of the child, and the infraction.
