Children must feel they are a vital part of something significant. One feels himself to be a part of that to which he lends significant contribution. A child that is served, but not called upon to contribute, will have low self-esteem. Everyone needs to be needed. Children will appreciate praise to the extent that it accurately reflects their real performance.
False praise is received as manipulation.
When children are part of a family team overcoming real obstacles, they know they are needed. Their contributions are essential, so they are essential. To struggle together and win together is the wedding of souls. Be what you want your children to be. More is caught than taught.
