We have a baby. She has a diaper bag. You know that, as a parent, you have to shove all different kinds of things into the bag when you go out. Outfits, diapers, wipes, burp rags, toys, binky, bottle, blankets, etc. This list goes on. After you shove the diaper bag full of all this stuff, how do you get to the things on the bottom? You have to unpack the whole thing. Time consuming and not a pleasant prospect when you are faced with a diaper blow-out on a nasty changing table in a public restroom!
