The humble schnoz may not come with an app, but your olfactory system is smarter than a sensor from Big Diaper

Diaper manufacturers are worried. American millennials aren't reproducing nearly as early or abundantly as their parents did, so the birth rate in the U.S. is falling. As are diaper sales. Cashing in on small humans' incontinence is harder than it's ever been.

To counter the effect of reproductive dwindling, diaper industry leaders have turned to price inflation, layoffs, and outright gimmickry. Pampers bumped the cost of their signature diaper by 4 percent last year, while Huggies' parent company Kimberly-Clark axed 13 percent of its workforce in January 2018. "You can't encourage moms to use more diapers in a developed market where the babies aren't being born in those markets," Kimberly-Clark CEO Thomas Falk told investors.
