Adults must teach their children how to save money, as this is going to play a very important role in their lives. This not only teaches them how to be responsible but also is going to show them that you need to have money in order to survive in this world.
Children are always watching, and they learn from what their parents do. When it comes to saving money, they can learn from watching you. As you save money and inform them how important it is, it will register in their minds. They will believe that if you are doing it, and benefiting from it, then it must be something important that they need to do too.
