Neccessity is the Father of Invention?

In all of my consumer-oriented ranting, I have completely failed to throw a link to the New York Times story from a couple of weeks ago that was first on the scene with their dads-as-drivers-of-American-consuming story. Interesting stuff:

In the history of child care products from strollers to the odor-eliminating disposal known as the Diaper Genie, plenty have been dreamed up by men and women alike. But as more fathers have taken hands-on roles in child rearing, tackling some of the grittier and more odiferous chores of parenthood and even becoming stay-at-home dads, their inventions are increasingly inspired by personal experiences like Mr. Habeeb’s. In many cases they are designed specifically for fellow fathers.

(Still not sure that I'm down with the shocked-that-dads-participate tone of the whole thing. The "grittier" chores of parenthood? "Even" becoming stay-at-home dads?)
