Will the real dose of infant tylenol please stand up?

I've gotten more than a few calls lately from parents who are rightfully confused about the recent change in the formulation of infant tylenol.  The old infant tylenol drops (with that little awful medicine dropper attached to the lid of the bottle) are now a thing of the past. 
But...to confuse things as much as possible, many stores are still stocking the old formulation, sometimes right beside the new liquid formulation, not to mention that many parents still have the old infant drops in their medicine cabinets at home.  If you count yourself among the many confused parents out there, here's the skinny on the new infant tylenol dosing guidelines.  READ THE FRONT OF THE BOX OR BOTTLE THAT YOU HAVE AND MATCH IT UP TO ONE OF THE CHARTS BELOW.
