I wrote about financial literacy that friends introduced for their two young girls, one a spender, the other not so much.
The thing is, the hole in the wall is, for most children, a cash cow, until you actually show them, what money comes in and what the obligations of the account holder are.
This was such an easy system where they dealt with real cash representing pocket money...some went into savings, some for spending and some for charity.
Once they could see how their personal savings were affected by their spending, things changed. They stopped being spenders, good for health, no treats, and better for the hip pocket.
These girls are learning as they go. One has just gone to high school, and wants to start real investing.
