I'm gonna have to agree with Cymomtx.
And please don't think this is any snubbing of your parenting skills. Cause I'm not the most perfect parent myself. WHAT????

That's crazy talk.
Before I went out and spent money on any behavior modification of any kind. I ask myself the same three questions.
1) Am I holding my kids accountable for their behaviors?
2) Am I rewarding bad behavior?
3) Am I holding myself accountable for my behavior?
I can be just as lazy as the next person. Sometimes more. But I try very hard to be honest with myself.
I have two girls 11 & 9. My nine year old has HFA and I and everone else in our family have done her disservices out of GUILT. If she is to become a functioning citizen of our community, I have to make sure that each of my actions don't go against the 3 questions listed above. No matter how much easier it is to let her veg in front of a SpongeBob marathon.
