How do you introduce a child to money and saving?

Concretely and early, because abstract explanations do not land. A small regular amount they control, including the freedom to spend it badly, teaches more than any lecture — the lesson comes from running out. Use physical cash initially since digital money is invisible to young children. Involve them in real decisions at the shop: comparing two options, noticing the difference between wanting and needing. Introduce the idea of saving towards something specific with a visible container or chart. Around ten to twelve, bank accounts and simple discussions about earning and interest become meaningful.
