I found this vid to be very powerful. Children see and hear so much, without you even realizing it (i once taught Early Childhood Education -Sunday School- to 3 year olds, and you'd be AMAZED the stories they came in with and questions they wanted answered). And you don't have to be a parent to have an impact on a child.
Let's set a good example for the little ears and eyes of the world watching us.

And, as a parent-- I always try to keep in the forefront of my mind "I have the ability to shape who my child is" (at least partially!) - Knowing that always makes me put extra effort and extra patience into every minute.
