Who knew I had something in common with the Kardashians? Surprise, surprise: The incredibly rich are not immune to working-mommy guilt. While promoting their new kids’ clothing line on CNBC’s Closing Bell yesterday, Kim, Khloe, and Kourtney were asked to respond to the recent comments by PepsiCo CEO Indra Nooyi that women can’t have it all. Whether or not you believe that what The Sisters K do actually counts as work—it certainly pays better than my job as an editor here at Money—their comments echo some of what I have heard from my fellow employed moms of the real world. “There are so many times I just didn’t want to get up and work on something, I just wanted to be at home with my baby,” Kim said. “I used to feel so guilty every time I left,” added Kourtney, who’s preggers with her third kid. I guess this is proof that every working mom has had regret about leaving their child with a caregiver at some point or another. (Though if I had three, I would probably feel elated about going to work, not guilty.) But for those of us who are the family breadwinners and those of us who simply love our careers, we know we have to power through. One way to beat back the guilt is to focus on the upside. And the good news is that there is a lot of research showing the benefits of being a mom who works (and this is not to vilify those who stay at home, who have the tougher job by my estimation). Remembering these four things helps me get through the tough mornings when my toddler breaks down in tears when I leave: 1. Working moms are healthier. A 2011 study from the University of North Carolina at Greensboro found that moms who work rate themselves in better health overall—more likely to say they feel “excellent”—than those who stay at home with their kids. This was confirmed by a 2012 paper from the University of Akron that looked at full-time working moms at age 40 who went back to work early on after having their children. These mamas reported higher levels of energy and mobility. I have to wonder, though, if either of these studies took into consideration what my husband and I have termed “daycare disease”—the family cold we pass between us from October to April. 2. Working moms are happier. Both the North Carolina and University of Akron studies showed that working moms exhibited fewer signs of depression than SAHMs. “Work is good for your health, both mentally and physically,” said Adrianne Frech, the lead researcher on the Akron study by way of explanation. “It gives women a sense of purpose, self-efficacy, control, and autonomy.” Additionally, a Gallup poll from 2012 found that moms who don’t work have higher levels of worry, depression, sadness, anger, and stress than those who do—which may speak to just how much harder that job really is. But you don’t need a study to tell you that you’ll actually be happier if you’re doing something you like. I mean, just take it from an expert like Kim Kardashian: “You know, for me, and I think I can speak for my sisters, it makes us feel good when we are out working and we can provide something for our friends and products that, you know, we can’t find that we really want. And it just makes you feel productive.” Of course, a lot of this depends on being in the right job. 3. Your kids will not suffer for it. In a recent Pew study, 60% of Americans said children are better off when a parent stays home to focus on the family, but there’s a lot of data showing the opposite. Kids of working moms turn out okay—and possibly better depending on what research you’re looking at. A 2010 review from the APA’s peer-reviewed Psychological Bulletin looked back at 50 years worth of studies on the children of working parents and found that those whose moms went back to work before the child turned three weren’t any more likely to exhibit behavioral or academic problems than those of moms who stayed at home. Among lower-income families, the kids actually did better on academic metrics. “Overall, I think this shows women who go back to work soon after they have their children should not be too concerned about the effects their employment has on their children’s long-term well-being,” said the study’s lead author, psychologist Rachel Lucas-Thompson. Other recent research has shown similar results, including a 2014 study out of Boston College which found that kids of middle-class working moms are as well prepared for kindergarten as childen of moms who don’t work, and children of lower-income working moms are better prepared. 4. Your kids will still love you. For her 1999 book Ask the Children, Ellen Galinsky, president of the Families and Work Institute, interviewed 1,000 kids ages 8 to 18 and found that a mom’s work status wasn’t a factor in how the children assessed their parents. In fact, the relationship between the parent and child was more important than whether or not mommy went to a job. Me, I’m reminded of this every day at around 6 p.m. While it’s awful to leave my kid in the morning—well, some mornings anyway—there’s nothing like the giant hug and sloppy kiss that’s waiting for me when I get home.
