Parents have the deepest love and concern for their children.
You also have the most direct and long-term responsibility for them. Your example and enthusiasm in learning with your children will motivate and encourage them far more than striving to appear as if you know it all. You do not need to know everything in order to teach. Home schooling magazines present articles that inform, encourage, and inspire you in various principles and techniques of home teaching. Provincial and local home school support groups can greatly encourage and help you as ideas and information are exchanged.
