Parenting advice has never been static. Every generation inherits a set of “commonsense” rules that feel airtight in the moment, only to look baffling a few decades later. Some of the practices parents once followed without question would today raise eyebrows, trigger a call to social services, or simply leave a pediatrician speechless.
The practices below weren’t fringe ideas. They were mainstream, doctor-recommended, and often sold in major catalogs. That’s what makes them so unsettling to read about now. Here are six old-school parenting facts that genuinely strain belief in 2026.

In the mid-19th century, Mrs. Winslow’s Soothing Syrup was considered a godsend for parents of fussy children. It was purported to treat teething pains, indigestion, and colic. The patented syrup was actually a dangerous concoction of morphine and alcohol, making it effective but exceedingly dangerous. Parents didn’t think twice about reaching for the bottle, because doctors and advertisers alike endorsed it.
The American Medical Association labeled the medicine a “baby killer” in the early 20th century after countless children died from overdoses or respiratory failure. Yet despite the AMA’s evidence, the product continued to be sold in the United States until 1930. In its extensive advertising across calendars, newspapers, and recipe books, Mrs. Winslow’s Soothing Syrup was also recommended to freshen breath and clean teeth. The marketing was as bold as the product was dangerous.

In 1928, psychologist John B. Watson published “Psychological Care of Infant and Child,” warning that maternal affection was dangerous. He promoted rigid schedules and discouraged cuddling, rocking, or any physical comfort, claiming this would build independence and self-reliance. Watson wasn’t some fringe voice, either. He was, at the time, one of the most prominent psychologists in America.
This approach was considered progressive and scientific at the time, influencing a generation of parents. Watson later admitted his own children struggled with the emotional distance he imposed. Today, leading experts in child psychology uniformly agree affection is a crucial piece of child development and parent-child bonding, which makes Watson’s advice read less like science and more like a cautionary tale.

As urban life became increasingly common for families, parents took unusual measures to make sure their children were still able to get “fresh” air. “Airing” was a term coined in the late 19th century referring to a practice wherein parents would periodically expose their children to the outdoor elements to toughen up their immune systems and aid in development. The concept was introduced by Dr. Luther Emmett Holt, who posited that exposing children to cold outdoor air would help them grow accustomed to it while “renewing and purifying” their blood.
By the early 1900s, countless parents, including future First Lady Eleanor Roosevelt, began improvising their own “baby cages” so their children could get exposure to the outdoors even while living in densely populated cities. Multiple patents for portable “baby cages” were awarded through the 1920s, and the trend continued through the first half of the century. These cages, primarily made of wire and fastened to highrise apartment windows, later fell out of fashion, likely due to a combination of safety concerns and increased urban air pollution.

As recently as the 1980s, some physicians were reportedly recommending pregnant women consume Guinness for its nutrient value. Guinness even co-opted the questionable medical advice for a misleading advertising campaign more than half a century ago. The logic was built around the stout’s iron and caloric content, which seemed convincing enough in an era before modern nutritional science.
Though Guinness does have some health benefits not seen in other beers, namely its higher levels of fiber and Vitamin B when compared to other stouts, this hardly proves the beverage’s antiquated “Guinness is good for you” slogan. Alongside being recommended to expectant mothers, Guinness was also routinely given to patients after operations to aid in their recovery. Today, no safe level of alcohol during pregnancy has been established, making this old advice particularly striking.
Children as Young as Four Were Sent to Work in Coal Mines

Throughout the Industrial Revolution, children in Britain became a prime source of cheap, unskilled labor for opportunistic businessmen. Children as young as 4 years old were frequently employed in British coal mines during the early 19th century, often working 12-hour days. This wasn’t hidden or treated as scandalous. For many working-class families, a child’s wages were simply part of the household economy.
Following the 1842 Children’s Employment Commission Report, public support for child labor weakened significantly after testimony from child workers depicting horrid conditions shocked the public. Subsequent legal acts and the expansion of compulsory public schooling largely eliminated child labor in mines by the turn of the century. The shift took decades and required public outrage, legislation, and a fundamental rethinking of what childhood was supposed to be.
Babies Were Put to Sleep on Their Stomachs, on Doctor's Orders

Stomach sleeping was doctor-recommended for 50 years before we discovered it increased SIDS risk. The reasoning at the time seemed perfectly sensible: placing an infant face-down was thought to prevent choking and allow the lungs more room to expand. Pediatricians repeated this advice confidently, and parents followed it without a second thought.
The reversal, when it finally came, was dramatic. The American Academy of Pediatrics launched its “Back to Sleep” campaign in 1994, and rates of Sudden Infant Death Syndrome dropped sharply in the years that followed. Most of the advice on taking care of infants and children was morally guided versus scientifically, and as a result, such advice often sounds strange or even downright alarming by contemporary standards. The stomach-sleeping story is perhaps the clearest example of how confident medical consensus can be, right up until it isn’t.
What’s striking about all six of these facts isn’t the ignorance behind them. It’s the confidence. Each practice came with expert backing, societal approval, and often a commercial product to make it easier to follow. The real takeaway may be the humility it invites: some things we treat as settled wisdom today will almost certainly look just as strange to the generations that follow us.
