How can we stop our child buying sweets?
When my daughter reached the age of six, my wife and I decided to give her a small amount of pocket money. However, access to money of her own would allow her to buy herself large quantities of sweeties. So instead of giving her cash in hand we keep track of the money she’s accumulated, which she can then use to purchase anything she wants so long as it’s not food or drink.
This worked well, but for her eighth birthday a number of kind friends and relatives gave her cash. She now plans to keep this money as an ongoing sweeties budget while buying birthday presents from her saved pocket money to show her benefactors.
Short of confiscating her birthday money, is there any way we can hope to discourage this?
Your daughter has discovered that money is fungible. As they say in the aid industry, you may think your grant is funding your favourite project, but it’s really funding the president’s favourite project. Thus, you give money on condition that it is spent on an extra hospital, the recipient builds the hospital he was planning to build anyway, sends you the receipts and increases his expenditure on limousines and AK-47s. (Did he spend your money on the hospital or the limousines? The question is meaningless, and that’s fungibility.)
Your plan worked only while your daughter had no access to outside sources of funding.
I can see three options. You rule out confiscation. The second is to offer incentives for low sweet consumption by increasing or reducing your daughter’s pocket money. The trouble is that sweet consumption may be hard to monitor. The third is to admit defeat and let your daughter make her own choices. Sweets have costs and benefits, and your daughter appears to be a better economist than you are.
