When I was childless and knew everything, I said things like:
1. I won't let my kid eat in the car.
2. I won't give my kid much sugar.
3. I won't get my kid fast food.
4. I certainly would never give my kid sugar as a reward for good behavior.
I now have a toddler, I know nothing and he loves Sonic ice cream. It seems to be working out okay...and carseat covers can be washed....
