I always thought "Baby On Board" caution signs were placed on cars and minivans as a courtesy to other drivers. These signs let other motorists know that the sign-toting car will swerve wildly, stop unexpectedly and misbehave drastically because a self-centered, totally implacable baby is present inside, jealously and continuously demanding the driver's attention by screaming, vomiting and pretending to fatally gag on nothing in particular.
