I have got both dds saving in a money box that gets put into the bank and they both have saving books where they can see the interest being added yearly (free money for just leaving it there, they say!!!)
Ive also explained to them about my credit card looking like im not spending anything, and showing them the huge amount on it at the end of the month and that it needs to be paid or they add extra money on top if you dont...
I want them to be sensible...what about you and yours?
