 Second mistake, the kids are thirsty, so keep them happy with a few cans of Mountain Dew. It's very easy to sip soda pop in the car. I'll be the first to admit it tastes good. But most sodas have those evil twins, sugars and caffeine. We all know the dangers of too much sugar. Empty calories, weight gain, high blood sugar. Kids are already facing these problems in ever-increasing numbers. Soda cans are easy to take away. Just do it.
