I really like this Kids Are Worth It parenting book (and audio) by Barbara Coloroso because it is full of such sound common sense. One of the hardest things to do in parenting is being consistent - and Barbara agrees. Start practicing your 'parenting skills' while you're children are a as young as possible - a rebellious teenager is much tougher to deal with.
Barbara's philosophy fits perfectly with the psychosocial development that you will find in Imago-style therapy and goes hand in hand with NVC and leads to confident contented kids. Together they can transform a dysfunctional home into a calm one - your whole family will thank you for creating a satisfying family life.
NVC alone offers great insight into your child's behavior - however, I like the no-nonsense approach of Kids Are Worth It and more often than not, the whole family benefits from Barbara Coloroso. If you read the book and want ideas on how to start applying what you've read to your own family, please feel welcome to email me.
Good luck!
