What Age?

I think 2.5 years old is the perfect age for a kid to learn about quid pro quo, or bribery as I like to call it.

• If you eat three more beans, you can have a cookie.
• If you leave school and come with me quietly, your Tow Mater is in the car.
• If you remember to say 'please' and 'thank you', you get more Christmas presents.
• Open your mouth wide while I brush your teeth and you won't get cavities.
• Sleep through the night and I will play with you tomorrow.

OK, so it's not bribery per se, it's more like an elaborate reward system for doing what I want.
