Baby on board
Before having a child, I was always puzzled by 'baby on board' car stickers. I'd naively think: Does this sticker magically make people drive better around you? Should people care more for your family's life because there are children in the car?
Now that I've been driving around with a baby for 6 months, it makes a lot more sense to me. What the 'baby on board' sticker actually tells me is that the driver of the car could be distracted, and is likely driving on limited sleep. I consider myself a good driver and someone who is calm under pressure, but let me tell you... driving with a screaming infant in the back is enough to test even the coolest of cucumbers. Add sleep deprivation, and you've got a genuinely dangerous mix.
Here is my suggestion for what the sticker should display (and what 'baby on board' actually means):

All this to say, be careful on the roads. And regardless of the reason for the sticker, don't be a dickhead behind the wheel.
