Educate your children to save

Buy a piggy bank to your son, or if you prefer to demonstrate that you intend to save money, use a cylindrical container for this purpose. Tell him that the money there, will not be put to use in the near future.

My suggestion is to offer your children an allowance, eg 10 €, and tell them that they should be teh one´s to define a weekly value of compulsory saving.

Teach them to set targets in order to acquire their first purchases, even though the value they can save is very low, this will inspire them with the notion of responsibility and show them the difficulty that adults sometimes have to spare.
