Too many equate spanking with beating and pool it in with hitting older kids...
Discipline and punishment.
Discipline: the practice of training people to obey rules or a code of behavior, using punishment to correct disobedience.
Punishment: the infliction or imposition of a penalty as retribution for an offense.
Seldom were spankings the lone "punishment" for me.
Often they were the softening up exercise.
The "attention getter".
Granted, the spanking hurt and was part of the punishment, but it MADE me sit in my chair in the corner, until I was told to leave it.
