Trepidation fills your heart as your "baby" is blossoming. The world seems ruthlessly bent on invading the sanctuary of values you uphold at home. Still, be firm. You are the one parenting your teens. By now in their life, your values have become evident to them. Trust them. Free the reins. Allow them to grow. And even if you haven't done enough, be secure in your own mind that you will continue to do so. And they will continue to grow mature. (Really, it does happen. Usually after the teenager years.)
