As the parent, you're the only one who can share the values that go with the facts. Let your affection show. Cut those apron strings. Trust your teen to make it all the way. Discipline Children need discipline.
Effective discipline teaches children how to avoid repeating misbehaviors and what to do instead.
Spanking is physical punishment, not discipline. There are many positive forms of discipline that are more effective than spanking. Discipline techniques should be appropriate to the age of the child. See the parenting section of your local book store or public library for information on child development and age-appropriate positive discipline technqiues. Babies are never candidates for discipline or physical punishment.
