"One of the most important gifts you can give your child is a positive self-image. A child with good feelings about himself or herself is much more likely to feel fulfilled socially, personally, and in the world of school and work than a child with a negative self-image. With a positive self-image, your child will face new situations with courage, deal with problems well, and be able to take risks.
All of us want our children to have a positive self-image, but we do not always know how to encourage our children to develop in these ways. To a great extent, your child’s self-image is a reflection of the feelings that you and others have communicated to your child. If you communicate to your child that you think your child is smart, fun to be with, and cooperative, that is the perception your child will have of himself or herself. If you communicate by your actions that your child never measures up in any way, your child will develop a negative self-image.
