I talk enough about chores and housework around here for you to know that this part of my job occupies much of my thoughts (and believe me, I don't have many thoughts to spare).
A year or so ago, we decided to start giving our kids an allowance. Their allowance is not tied to their chores--they are expected to do their chores because they are a part of our family, and I didn't want to give them the option of saying they weren't going to do their chores because they didn't want the money that week. But I wanted them to start learning to handle money as well, hence the allowance.
Since the institution of the allowance, we have always said that if our kids want extra money, they can earn it by doing chores beyond their normal, expected chores. It sounded good, but was problematic because we never had jobs at the ready for them to do when they asked us. And I've never been all that great at thinking on my feet (this is why I write instead of talk).
Until now. I thought I'd share my solution with y'all.
Happy work for hire-ing :)
