1. Too little downtime together as a family. This is what gives your child the roots and skills they need to get through the challenges in life.
2. Love them for who they are. Many parents are too stingy with expressing appreciation, acceptance & validation of their children.
3. Children are not possessions; don't use them to express yourself.

If you get it right, they'll come to you when the going gets rough, but you have to make sure they KNOW you're a good listener.
