I once read that values are like viruses because they’re caught in the environment within which they reside. That statement had a powerful impact on me as a parent and brought to my attention that you have to begin teaching your child values from the time they are very small.
Children learn from what they hear and observe so the best way to teach values is to set a good example.
Tell a story about how you learned a lesson when you were young that will help your child better understand the difference between right and wrong. Kids will listen. Explain your reasons for what you say and how you act. This will demonstrate how you use your values to make decisions.
