I would do anything to not go to the playground," Cara says. "I am bored to tears in playgrounds."

The mother of two children under the age of 10, the 39-year-old Calgary lawyer also hates kids' birthday parties and took only three months of maternity leave -- both times. She now has a live-in nanny who she says "basically raises my kids."

Cara is not alone. American expatriate Helen Kirwan-Taylor recently admitted in Britain's Daily Mail that her children "bore her to death." 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. They've lived and learned before having children. They've travelled. They've worked. They are adamant that Mother Love does not (and should not) conquer all. You could even call them a new wave of straight-talking feminists.

Take Amalia Jimenez. The Torontonian says bluntly, "We would be in complete denial to say that every element of child rearing is interesting. In one of my postpartum moments, with three sons, I looked at my mother in terror and said, 'When does it ever stop?' She said, 'Never!' I started to sob."

Ali Martell, a children's book editor and the mother of two young children, is equally frank. Her version of freedom is leaving her kids behind (at least sometimes): "You envy your single friends, the ones who can just go out at a moment's notice for dinner, or a movie, or even to the supermarket without having to think about the kids first."

Or, as journalist Ms. Kirwan-Taylor put it so candidly, she finds taking her kids to the park 'tedious" and can't bear a family film outing without "texting friends."

"Research tells us that mothers drink the most when they have young children," she wrote. "Is that because talking to anyone under the age of 10 requires some sort of lobotomy?"

Of course, as Ms. Paesel points out, mothers have been complaining subtly about the monotony of parenting for years.

But she says, "In the past, the complaining has been accompanied by equivocation. A mother might say, 'I adore my children, but sometimes I think it might be fun to have a few minutes to myself.' When said that way, no one hears it. Everyone hears it when you say, 'My children bore me to death.' "

Catherine Connor is one mother who avoids equivocation. A former university instructor, she now writes a weblog called Her Bad Mother that pulls no punches about the downside to breeding. "Mommy bloggers remind each other all the time that bitching and moaning does not equal bad mother," she says. "Those who complain about motherhood, especially if they do so intelligently, let other women and mothers know that it's okay to be honest about what motherhood is really like."

Joanne Snider goes one step further. "People who admit it's boring are heroes," says the 37-year-old single mother of a 17-year-old son. "Some parts of parenting, no matter what age your children are, are dull as dishwater. That's okay. For people to pretend all of it's exciting is a big lie, and doesn't serve anyone."

Which raises the question: Why the backlash, more painful than natural childbirth, against women like Ms. Kirwan-Taylor? In the aftermath of her article, the 42-year-old has said she's the most "vilified" woman in England because she doesn't find changing diapers "interesting." Are modern mothers, who have grown up in wealthy and democratic countries, believing the world is their oyster, simply spoiled? Or selfish?

Sarah Bingham, a mother of two and the founder of an on-line directory for new and expecting parents called Canadianbabies.ca, thinks spending time with your kids is part of a mother's job description. She says parenting is about balancing and that "uninvolved" mothers are really "unattached" mothers.

"Parents bored of their children? Come on! . . . Find a way to get involved with your children and spend time with them," she says, listing off mother-child activities such as movies for mommies, sign-language classes and infant massage.

But Ms. Paesel suggests that the hostility of what some call Martyr Mommies or sanctimommies against SMUMs isn't totally selfless. "We all were children once. And we find it hard to accept that possibly we weren't endlessly fascinating to our parents," she says.

"I remember being hurt when my mother revealed to me that the happiest time of her life was the period when she went back to work after I was in high school. Now, I think it's wonderful she didn't build her existence around me. But at the time, I thought, 'How can raising me not have been the most fulfilling thing on the planet?' "

(Interestingly, although Ms. Kirwan-Taylor's son defended her in an interview, saying he would be driven to drink if he were a mother, one reader wrote in response to her piece: "There's nothing more calculated to demolish your sense of self-worth than a parent who doesn't think you're the centre of their universe.")

Devra Renner and Aviva Pflock, authors of Mommy Guilt: Learn to Worry Less, Focus on What Matters, and Raise Happier Kids, on the other hand, see wider social pressures at work in the outrage against bored mothers. When women admit that mothering isn't always as fulfilling or exciting as getting a new haircut, they rebel against notions that women have some sort of inborn, single-minded maternal instinct. (Where these women's husbands are in the child-centric debate is another issue.)

"Women are not supposed to feel negative about mothering," Ms. Renner says. "We define 'mommy guilt' as all the negative emotions associated with parenting: anger, frustration, lack of control, fear, sadness, boredom. These are things that society does not support women feeling when it comes to taking care of our own children."

Dare we ask Ms. Pflock, a child-development specialist and mother of three, if she finds motherhood boring herself?

"Of course it is. As is our work, as is our favourite hobby -- even a marriage or other relationships can be, at times, boring. Not everything in life is going to entertain us all the time. There may even be entire segments of parenting you find boring, not just a day or a time of day. One mother may love thinking up activities to entertain her preschooler all day long, while another can't wait for all-day kindergarten to start. As long as we love and care for our children in a way that is fulfilling to everyone over the course of time, we are doing just fine."
