It is very interesting to discuss money, according to its function as a medium of exchange that is generally accepted in the community to make payments for the purchase of goods or services.
I have 2 sons, every day I give them pocket money, teach about using money well and discuss money matters casually.
From an early age I taught my child to use money as needed and save money. Set aside a portion of the money I give for savings for later use. Even though he can get a lot of money later, don't forget to save or invest.
Of course not only theory, I apply it also in everyday life when my child wants to shop at a supermarket, to buy products as needed and the rest is stored for other purposes such as: if he wants to buy more quality goods there is a reserve fund, want recreation and contribution social can be taken from money saved in savings.
I do not limit my children to making money, always teaching them to work hard and lead a simple life.
Have a nice day.
