How to Regulate Children from Eating Too Much Candy

How do you regulate this kid from eating too much candy?

Some possible solutions are:

1. You leave the kid alone, but tell her to only eat one every day.
2. You just leave it to her to decide how much she wants to eat (and can manage to eat!).
3. You take her away from the candy (alternatively, simply remove the candy).

Any sensible grown up would know which one of the above is the correct answer, even though the choice could be a tough one to take as the result could really be heartbreaking.

The moral of this regulatory exercise is simply let's hope the Federal Reserve never gets involved in regulating children's intake of candy.
