I had just started at a new church, and one of the parents asked their six year old what they thought of me.  Her answer was, "I like him.  He gets down on his knees and he talks to me face to face."

Standing is a sign of authority.  Kneeling is a sign of humility.  There are certainly times we need to stand and talk to the kids, there are also times we need to, "get down on their level."  Jesus is the perfect example, he who is God came down on our level and became a man.  And when ministering to the kids, the Bible tells us that he took them in his arms, which means he either sat down to their level and held them, or he picked them up to his level.
You will be amazed at the effect of something small like this has on the attitudes of your kids.
