I also found this interesting so here 'tis. 

THE DIAPER CHANGE: TV TROPES

Here's a pretty spot-on summary of the way the use of diapers by babies and the subsequent task of changing them is often handled in popular culture.

I would like to add two more:

Nobody ever shuts up the person whining about diapers by pointing out that someone had to change them.

Second, even when a newborn or infant has a dirty diaper, it still stinks, even though diapers don't begin to smell that way till the child starts eating solid foods, or so I am told.

At any rate, the examples stated below the main content in the link should invoke some feelings of nostalgia, if not also disgust and a sudden desire to cut the cord.
