Younger adults love their boomer parents and relatives, but that does not mean they understand them. From money secrets to old-school parenting, certain habits feel wildly out of step with how Millennials and Gen Z live now. Here are 11 classic boomer traits that younger generations say drive them up the wall, and why those patterns clash so hard with modern expectations.
1) Withholding financial details from partners
One big generational clash is over money transparency. Younger adults increasingly expect couples to share account logins, debt numbers, and long-term goals, and a recent survey found that younger generations explicitly value financial openness in relationships. Baby Boomers, by contrast, often grew up with “his money” and “her money,” or with one partner quietly handling everything while the other stayed in the dark.
That habit can feel secretive or even unsafe to younger partners who are juggling student loans, rising rents, and shared subscriptions. When one person keeps separate “rainy day” accounts or hides credit card balances, it clashes with the expectation that long-term partners should be teammates. The frustration is not just about trust, it is about trying to plan for housing, kids, or retirement when half the financial picture is missing.
2) Relying on physical discipline like spanking
Another sore spot is the way many Baby Boomers were taught to parent, especially around discipline. Millennials in one viral thread described how their boomer parents treated spanking, slapping hands, or grabbing arms as normal, even loving, ways to keep kids in line, and they shared those experiences in detail through personal stories. For younger generations who grew up with conversations about trauma and child development, that approach feels harsh and outdated.
Today, a lot of Millennial and Gen Z parents lean toward time-outs, natural consequences, and calm explanations instead of physical punishment. When they see older relatives joke about “a good spanking” fixing behavior, it can reopen old wounds and spark arguments about what counts as abuse. The stakes are high, because these disagreements shape whether grandparents are trusted to babysit and how safe younger parents feel in their own family homes.
3) Letting kids roam freely without supervision
Letting kids disappear on their bikes until the streetlights came on is a classic Boomer childhood memory. Millennials responding in that same discussion about quirky habits said their parents still brag about being “free-range” kids, walking to school alone or wandering malls for hours. To younger adults who grew up with Amber Alerts on their phones, that level of freedom can sound less like nostalgia and more like neglect.
Modern parents are constantly reminded of worst-case scenarios, from viral news stories to location-sharing apps like Life360. When Boomer relatives roll their eyes at playground supervision or insist that kids should “toughen up” by roaming the neighborhood, it creates tension over safety standards. Younger generations are not necessarily against independence, but they want it balanced with realistic risk management, not just “we survived, so it must be fine.”
4) Smoking cigarettes indoors around children
Smoking inside the house, the car, or even over a baby’s crib used to be routine, and many Boomer parents still talk casually about lighting up anywhere. Millennials recounting their childhoods in the same set of frustrated memories described parents and relatives who smoked in living rooms, restaurants, and cramped cars with the windows barely cracked. Another common quirk among Boomer parents is their tendency to save everything, from old receipts to outdated manuals, often cluttering the home, and those smoky, cluttered spaces are burned into younger people’s memories.
For adults who grew up with anti-smoking campaigns and strict smoke-free laws, that habit feels shocking in hindsight. It also feeds ongoing conflict when older relatives still minimize secondhand smoke or insist on smoking near doorways during family gatherings. Younger generations are more likely to set hard boundaries, like no smoking anywhere on the property, which can feel like a personal attack to Boomers who once saw cigarettes as a normal part of daily life.
5) Skipping car seats and seatbelts for young kids
Car safety is another area where Boomer norms clash with modern expectations. Stories about Riding in cars without seatbelts or car seats are practically a genre of their own, with Boomer children piling into station wagons and lying in rear windows. Many Millennials say their parents still joke that they “turned out fine,” even though safety standards have changed dramatically.
Today, parents are told to keep kids in rear-facing seats for years and to use booster seats well into elementary school. When Boomer grandparents roll their eyes at the extra buckles or try to hold a baby on their lap “just for a short drive,” it sets off alarm bells. Younger adults see strict car-seat rules as non-negotiable life-or-death protections, not overprotective fussiness, and that difference can lead to serious arguments before anyone even leaves the driveway.
6) Enforcing strict gender roles in play and chores
Strict gender roles are another habit that grates on younger generations. Many Boomers grew up with clear lines about what boys and girls should do, and Millennials in those younger perspectives say their parents still default to that script. Baby Boomers often underestimate the financial challenges that younger generations face, offering simple cost-cutting solutions without fully understanding modern pressures, and that same mindset can show up in how they divide labor at home.
When a Boomer grandparent buys trucks for grandsons and dolls for granddaughters, or expects daughters to help in the kitchen while sons relax, it clashes with how Millennials and Gen Z talk about equality. Younger parents want kids to see all chores and hobbies as fair game, regardless of gender. These small, repeated moments send big messages about who is valued and who is expected to serve, which is why they spark such intense pushback.
7) Dismissing talks about mental health struggles
Mental health is one of the sharpest generational divides. Many Boomers were raised to “tough it out” and avoid discussing anxiety, depression, or burnout, and Millennials say their parents still treat therapy as something for people who are “really sick.” In collections of Survey responses, Millennials and Gen adults describe Baby Boomer relatives who dismiss panic attacks as drama or insist that work stress is just part of life.
Younger generations, by contrast, are more likely to talk openly about diagnoses, medication, and boundaries at work. When they hear “we did not have time to be depressed,” it feels like their real struggles are being erased. The stakes are serious, because this gap can keep people from seeking help or from confiding in family members who might otherwise be a support system.
8) Prioritizing material rewards over emotional support
Another pattern that shows up repeatedly is the focus on providing things instead of feelings. Millennials sharing their experiences with Boomer habits describe parents who worked long hours, bought big Christmas gifts, and kept every receipt and manual, but rarely said “I am proud of you” out loud. The clutter of saved stuff, from old appliances to stacks of paperwork, becomes a symbol of how material security was prioritized over emotional connection.
For younger adults who value quality time, verbal affirmation, and mental health, that dynamic can feel hollow. They appreciate the sacrifices that paid for college or sports, yet still wish their parents had been more emotionally present. As Millennials and Gen Z raise their own kids, they are trying to keep the best parts of that work ethic while also building homes where affection and vulnerability are not treated as luxuries.
9) Using television as constant childcare
Endless TV time is another habit that younger generations question. Many Boomers saw television as a harmless way to keep kids occupied while they cooked, cleaned, or relaxed, and Millennials recall entire afternoons spent in front of cartoons or game shows. In the same collections of Millennials sharing frustrations, people describe parents who treated the TV as a default babysitter whenever they needed quiet.
Today’s parents are not screen-free, but they are flooded with research about attention spans, sleep disruption, and targeted advertising. They also have more options, from interactive apps to supervised YouTube playlists, and feel pressure to curate every minute. When Boomer relatives shrug off those concerns and turn on whatever channel is handy, it can feel like they are ignoring both science and parental boundaries, even if their intentions are simply to entertain the kids.
10) Avoiding open discussions on sex education
Sex education is another area where Boomer silence frustrates younger adults. Many Millennials say their parents relied on school programs, vague warnings, or religious rules instead of clear, factual conversations. In threads about boomer parenting, people describe getting cryptic comments about “saving yourself” but no real information about consent, contraception, or LGBTQ identities.
By contrast, Millennials and Gen Z are more likely to see open, age-appropriate talks as essential safety tools. They want kids to understand their bodies, boundaries, and options long before they are in risky situations. When Boomer relatives push back on that approach, insisting that too much information will “encourage” sex, it creates a tug-of-war over who gets to shape the next generation’s values and health decisions.
11) Insisting on traditional nuclear family norms
Finally, many Boomers still treat the traditional nuclear family as the gold standard, and that insistence can feel suffocating to younger generations. Millennials in collections of younger frustrations describe parents who assume everyone will marry young, have biological children, buy a suburban house, and stick to that script for life. Any deviation, from staying single to choosing not to have kids, is treated as a phase or a problem to fix.
For Millennials and Gen Z navigating gig work, high housing costs, and more fluid identities, that one-size-fits-all model simply does not match reality. They are building chosen families, co-living arrangements, and blended households that look nothing like 1950s sitcoms. When Boomer relatives refuse to recognize those structures as valid, it strains relationships and makes younger adults feel unseen in the very families they are trying to modernize.
