Bestselling Author Jane L. Rosen Banned from Upper East Side Mommas Facebook Group Over Book's Critique of Elitism

Jane L. Rosen, a seasoned Upper East Side resident and author of the 2020 novel *Eliza Starts a Rumor*, found herself at the center of a digital feud that has since spilled into the public eye. The bestselling writer, who had spent over three decades navigating the social intricacies of Manhattan's most exclusive neighborhood, was eager to share her latest literary success with her online community. Her plan: a virtual book club for members of the UES Mommas Facebook group, a 44,000-member forum known for its exclusivity and combative tone. But when Rosen checked the group's invite list ahead of the event, she discovered a shocking reality—she had been banned. The moderator, Tiffany Ma, cited a passage from Rosen's novel as the reason, a section that poked fun at the neighborhood's elite culture. "If you can't joke about a Birkin bag on the Upper East Side, where can you?" Rosen told the *Daily Mail*, her voice tinged with disbelief and frustration.

The incident has exposed the undercurrents of rivalry that simmer within these mom groups, where social standing is often measured in the clout of one's digital presence. UES Mommas, along with its counterpart Moms of the Upper East Side (MUES), has long been a breeding ground for both camaraderie and cutthroat competition. Members frequently share details about their financial portfolios, boast about their children's achievements, and air grievances that range from petty squabbles to full-blown betrayals. One mother, who joined both groups during her children's early years, described the environment as "a keyboard-armed fight club." She told the *Daily Mail*, "There are mean girls. These women are crazy. I think they're all going to f**k up their kids, honestly, I really do." Her words, while harsh, reflect a sentiment echoed by others who have witnessed the group's more toxic tendencies.

The exclusivity of these forums is enforced with ruthless precision. Members who cross the invisible boundaries of acceptable behavior—whether by humor that veers too close to satire or by failing to align with the group's unspoken rules—face swift and severe consequences. Exile from the group is often the ultimate punishment, a social death that can ripple through the neighborhood's tightly knit circles. For Rosen, the removal was particularly jarring. Her book, which centers on a suburban mother whose online posts ignite a scandal, had been intended as a lighthearted commentary on the absurdities of elite mom culture. Yet the passage in question, which mocked the Upper East Side's fixation on luxury brands and the surreal spectacle of nannies playing mobile games while their charges collected syringes from playgrounds, struck a nerve.

Beyond the drama of Rosen's exclusion, the *Daily Mail* uncovered a broader landscape of posts that reveal the groups' obsession with wealth, status, and the minutiae of affluent life. One member, who described her household income as $700,000 annually and her assets as $1.5 million, questioned whether she was eligible for financial aid at a K-12 school—a query that sparked a flurry of responses from peers debating the ethics of private education funding. Another post asked, "If you had $2 million plus a cash gift from grandparents, would you use it to send two kids to private school?" A third wondered if it was now "normal" to include a 529 account link in a child's birthday invite instead of traditional gifts. These exchanges, while ostensibly about parenting, often veer into the realm of social signaling, where even the most mundane details are dissected for their implications on status and privilege.

The groups also serve as a marketplace for services, albeit one that can feel absurd to outsiders. A recent post from a mother seeking help packing her suitcase for a trip drew comments ranging from bemused to outright judgmental. "To me, that's nuts," the former member said, recalling her own time in the forums. "These people have so much money they'll pay for anything." Others shared stories of lost luxury items, like a Chanel bag misplaced at an upscale restaurant, or requests for recommendations on sleep trainers for toddlers—services that, to some, seem excessive but to others are simply another facet of life in a world where even basic needs are met with extravagance.

As the feud between Rosen and Tiffany Ma continues to play out in the public sphere, it has become a case study in the paradoxes of elite mom groups. They are spaces where women ostensibly come together for support, yet they often devolve into arenas of social exclusion and backstabbing. The lines between humor and insult, solidarity and rivalry, are blurred by the very wealth and privilege that define the community. For now, the UES Mommas group remains a closed chapter, its inner workings known only to those who have survived its trials—or perhaps those who have been cast out.

Hey, does anyone else have a story about scoring a Hermes bag at the Madison Avenue store?" one member wrote, sparking a firestorm of debate in the exclusive Upper East Side mom group. The post, which quickly drew dozens of replies, included a string of pointed questions: How much did people spend before getting an offer? How long did it take? And who was the most helpful sales associate? The exchange quickly turned sour as one poster snapped, "Why would you want to spend thousands of dollars only to be 'invited' to spend thousands more?" Another chimed in with a sharp critique: "The whole reason Jane Birkin was an icon is that she didn't have to try so hard. Stop trying so hard."

The conversation wasn't just about luxury goods. A mom posed a bizarre question about replacing party favors with contributions to her child's investment account, while another asked if it was acceptable to ask guests to donate to a 529 plan instead of giving toys. Meanwhile, a different mom raised concerns about "boundaries around food" for her nanny, sparking a detailed exchange about whether it was typical for caretakers to eat from the family's kitchen. One member shared, "Our nanny usually makes herself breakfast using our food—two eggs, a bagel, sometimes a banana every morning. And when she cuts fruits for my daughter, she'll have some too. We also let her drink anything in the fridge and eat snacks from the cabinet. Is this typical? Do you set any boundaries around food, or is it more of a 'help yourself' situation?"

The group, once a lifeline for parents seeking advice on everything from pediatrician recommendations to playdate ideas, has become a breeding ground for drama. One longtime member, a speech pathologist, said she stopped participating because the tone had shifted. "Feels a bit like high school," she told the *Daily Mail*. "No thanks." Another, a physician and 14-year UES Mommas veteran, admitted she now relies on ChatGPT for planning vacations. "The group was indispensable for me for so many years," she said. "Now I use AI, so I don't need the group."

The drama isn't limited to private conversations. At lunch meetings, members joke about who they're bashing that day. "We meet for lunch and we're like, 'All right, who are we bashing today?'" one said. The group's exclusivity has only intensified since 2020, when high-powered lawyer Ma took over as moderator after a series of scandals. Sources told the *Daily Mail* that the group now requires ultrasounds, pregnancy photos, proof from OB/GYNs, and even birth certificates for membership. "I was told the admins were asking for ultrasound photos," one member said. "That is bananas."

The group's reputation for gossiping, nanny-shaming, and exposing affairs has led to outside scrutiny. When the *Daily Mail* infiltrated the forums, they found posts bragging about 401Ks, savings accounts, and assets. One controversial post, which was publicly criticized by TikTokker Bryce Gruber, asked if it was wrong to fly private while sending a child to soccer camp in coach. Over 130 moms responded, with one defending the parent's choice: "Having preferences doesn't make you a bad parent—at least you're not depriving your child of an experience."

Valerie Iovino, who runs MUES, the group's parent organization, told the *Daily Mail* that the community has grown to nearly 40,000 members and hosts regular in-person events. But for many, the group has become less about support and more about social climbing. "It's all behind closed doors," one source said. "But the walls are thin."

As the group tightens its grip on exclusivity, some members wonder if it's still worth the cost. For others, the drama is just another part of life on the Upper East Side.

A growing number of mothers on the Upper East Side are finding themselves entangled in a web of controversy, as one of the region's most influential Facebook groups faces renewed scrutiny over its increasingly contentious internal dynamics. The UES Mommas group, which started in 2011 as a community for mothers seeking advice on everything from school choices to holiday traditions, has become a lightning rod for drama, with members clashing over everything from political discourse to deeply personal privacy concerns. Recent revelations about the group's alleged membership practices have sparked fresh debates about online accountability and the boundaries of digital communities.

"I have never required the submission of private medical records or personal documents as a condition of entry," said one group administrator, who spoke to the Daily Mail under the condition of anonymity. She described how some rival groups reportedly demand invasive documentation—such as ultrasound images, adoption papers, or birth certificates—as a barrier to entry. While she dismissed such practices as unnecessary, her comments come amid growing unease about the role of online forums in policing personal information. "When in doubt, I simply deny entry," she added, though she acknowledged that group administrators are not legally bound to protect voluntarily shared data.

The UES Mommas group has long been a fixture in local news cycles, with its history marked by escalating conflicts. Four years after its founding, in 2015, the group erupted over Wednesday Martin's book *Primates of Park Avenue*, which painted a critical portrait of UES mothers as women who "earn wife bonuses" through their domestic performances. By 2017, the group had ballooned to 27,000 members—and with that growth came a bitter ideological divide. A fierce debate over the Black Lives Matter movement led to legal threats and expulsions, with two mothers sending cease-and-desist letters to critics before being banned themselves.

The group's reputation for inciting drama only deepened in 2020, when members accused moderators of silencing voices of color following George Floyd's murder. That same year, the forum briefly shut down after author Golbarg Bashi's post about her children's book *P is Palestine* drew accusations of anti-Israel bias. Upon its return, moderators imposed new rules explicitly banning political discussions, a policy that has since been repeatedly tested.

Fast forward to 2023, and the group finds itself once again in turmoil, this time over New York's newly elected mayor, Zohran Mamdani. Members have accused each other of Islamophobia for suggesting they might flee the city to Florida after Mamdani's inauguration. In response, moderators have introduced "Anonymous Posting Rules," which prohibit members from attacking or threatening others—even when posting anonymously.

For many longtime members, the group has become a double-edged sword. "Everybody's anonymous now," said one mother who has been part of such groups for 14 years. "It's really easy to be nasty if you're hiding behind your iPhone." She described the group as a place where users often present idealized versions of themselves, creating a toxic environment where comparisons and jealousy fester. "You could get in these groups and think everyone has perfect lives," she said, "but we know it's not like that."

Some members have even chosen to disengage entirely. "I have friends who refuse to be on Facebook anymore because it gives them so much anxiety," another mother noted. For others, the group remains a source of both connection and frustration. As one expelled member put it, the appeal lies in the "voyeuristic aspect" of scrolling through other people's lives. "People just love a good scroll," she told the Daily Mail. But as the group continues to grapple with its own internal tensions, the question remains: can a community built on shared parenthood survive the very drama it once sought to escape?
