shelly,
Here's the thing, just as everyone is different, each difficult child is very, very, unique. Part of their gfgness is the trait of not following that which makes others tick! Most of us have found that a combination of many discipline/behavior mod techniques is what works. And, what works one month may very well change in five.
Just as each difficult child responds differently to medications, each difficult child will respond to a program like typical teen in their own unique way. It's a roll of the dice. If you are willing to pay the price for the program......
