The newest round of the mommy wars over balancing work and life came when Mayer, chief executive of Yahoo, broke new ground by being one of the first CEOs to speak publicly about parenthood.
"The thing that surprised me is that the job is really fun . . . and the baby's been easy. The baby's been way easier than everyone made it out to be. I've been really lucky that way," Mayer said last week at Fortune's Most Powerful Women event, prompting a firestorm.
Some women thought that Mayer, with her huge salary and paid support staff, was setting too high a bar for other women, who might struggle with not-so-easy babies, financial constraints, and a job outside the home.
Of course, that means that Krispy, the shift manager at the local diner, will now certainly be empowered to fire his swing-shift waitress when she's late after a night with a collicky baby.
It's hard to say that fear is wrong - we have light years to go before we're a nation that truly has family-friendly workplaces.
Underscoring this truth was this year's talker by Anne-Marie Slaughter, a Princeton professor and former top aide to Hillary Rodham Clinton, who explained in Atlantic Magazine "Why Women Still Can't Have It All."
But here's the deal: Every kid is different, every mom is different and talking about it is the only way to make progress.
Yes, Mayer undoubtedly has great paid support. She probably isn't running out to get groceries on her lunch hour or vacuuming while attached to a breast pump.
But the truth is, those of us who do or have done all that also aren't chief executives of a multibillion-dollar company with 12,000 employees whose strategies are analyzed by Goldman Sachs and whose leadership decisions are instantly translated into percentage points on the New York Stock Exchange.
I sure as heck hope she's got a supportive spouse and quality child care that will help her with the baby while she takes the helm of a major tech company.
Hearing Mayer addressing her role as a mother in any fashion is refreshing. It busts down the idea that women have to act like men and leave behind anything that reminds people they are women to make it in the business world.
Take the empowerment talks of Sheryl Sandberg, chief operating officer at Facebook, who encourages young women to forge ahead while admitting that she concealed for years that she left the office at 5:30 p.m. to be home with her kids.
Talking about that is daring. Women made up only 14.1 percent of executive officer positions in Fortune 500 companies last year, even though women are 46.6 percent of the workforce, according to the research firm Catalyst.
But it can't only be up to chief executives to be the role models representing all working moms.
Ann Romney was right - even with a huge pot of resources and no outside job, raising five children is harrowing.
Imagine how hard it is for a parent with no partner, limited income, and no choice but to work outside the home. It's an issue that was barely addressed in the presidential campaign.
Each time one of these women speaks publicly about the balance of work and parenting, we get a little closer to understanding that this is an issue about families, about society, about the wellness of our community.
You want to know when real progress is made? When we hear a CEO speech about leadership that includes tales of long, collicky nights - from a dad.
