So, you have attempted to use the Christian Parenting Class, but you did not get any results?

The next step is to use the Strategic Parenting approach.  This is an awesome  program designed to work with difficult children.  I advise you to seek out a therapist that is trained in Marriage and Family Therapy with experience using Cognitive Behavior Therapy or Strategic Therapy.  This is a program designed to educate you as a parent to be smarter than your children.  The goal is to be on step ahead of your children.  If you notice that nothing works, you children do not listen to you or you feel like you have tried everything, this might be the best program for you.  Your goal is to be calm, direct and firm.  Communication is essential. If you child is not listening to you, you need to consult your therapist, so they can help you improve your ability to reach your child, because every child is different.
