n. A woman who finds motherhood and her children tedious and uninteresting.
In her new book, Mommies Who Drink, U.S. actress Brett Paesel confesses she would rather hit happy hour with her friends than have "fun with felt." And the blogosphere is exploding with posts from mothers telling the dirty truth that motherhood is, well, mind-numbing.

Dubbed SMUMs — smart, middle-class, uninvolved mothers — these women are no longer willing to feign interest in watching Barney for the 538th time.

So now it's on between the SMUMs and the SCAMs (Smart, Child-Centered, Active Moms — my coinage). SCAMs are the superachieving moms who hand-letter birthday invitations, spend their days in imaginative play with their toddlers, bake from scratch and joyfully embrace each moment spent with their supergifted offspring.

I know (and have been known to like) these women. I even have moments when I wished I had their game, but I can only be the SMUM that I am: distracted, well-meaning, ambitious for myself. But my kids know I'll always be there for them when the chips are down, even if I'm not actually going to get up to serve them any chips.

Why did Helen Kirwan-Taylor have a second child when she finds motherhood utterly boring?

Was she shallow enough to simply want a 'matched pair' — she admits 'matching shoes to a skirt' is very important to her. Or did she think her first child needed a sibling for the entertainment she wasn't going to provide herself?

As a psychologist, I find her attitudes disturbing and ridiculous. They encapsulate the worst of modern motherhood and are prevalent in a group I call SMUMs — Smart, Middle-Class, yet Uninvolved, Mothers.
