It may not be as easy as you think to build a foundation for your child of family values. Often we believe that our child will pick up on our values if they live in the same home. While they may pick up many of our values, parents need to remember they are not the only influence in their child's life. These outside values often compete with family values for your child's attention. If we do not make a conscious effort to instill our values into our children, they may not get instilled at all.
I wish I had learned that lesson a little earlier. I thought if I lived my values for my children they would pick them up and make their own. Sometimes this happened and sometimes it didn't. I often see twenty-something “kids” who have no faith in many of the values of their family in favor of the values of their friends. Children will often pick up the negative you show quicker than the positive, so the positive things need extra focus to set them.
Some of the influences your children face every day include their church, their school, their friends, any clubs or sporting groups they are part of and more. Kids spend many hours a day at school and with their friends. Sometimes in the business of life, we suppose our children will obtain that foundation we want for them.
Instilling a foundation of family values to sustain(维持) your child requires more than living it in front of them. That is important, but building up your child with this important foundation must become intentional.
That means we plan times to gather as a family. We plan activities together that show the values we want to pass on. We talk about our values; we live our values; we discuss the values of others and how they differ from ours; we constantly look for opportunities and make our own opportunities to share these values in word or deed with our children.
Family values give our children a foundation to build upon. It helps them know they are loved and gives them a sense of belongings. Upon this sure foundation, they can spread their wings and grow to become parents who share these same values with their own children.
