When we think about newborns, we often imagine them as tiny beings who do little more than eat, cry, and produce endless tears. However, this perception isn’t entirely accurate. In fact, newborns have surprisingly rich inner lives, and there’s much more to them than meets the eye. Let’s explore some common misconceptions about babies and uncover the fascinating truths behind them.
One surprising fact is that newborns don’t actually cry tears right away. Most babies don’t produce visible tears during the first few weeks of life. The lacrimal glands, which are responsible for tear production, typically start functioning around two weeks after birth. It’s common for tears to become noticeable only weeks or even months later. Interestingly, many people mistakenly believe that tear ducts are responsible for producing tears, but that’s not the case.
The idea that babies are born as “blank slates” has been around for centuries, with philosophers like John Locke and David Hume discussing the concept. Locke described the mind’s starting point as a blank piece of paper, devoid of any knowledge. While this was more of a philosophical starting point than a literal description of a baby’s mind, many people still view infants as having no prior knowledge or awareness.
However, recent scientific advancements have challenged this notion. Researchers like Robert Fantz discovered that the amount of time a baby spends looking at something can indicate interest or surprise. For instance, studies have shown that four-day-old infants prefer the language their mother speaks, suggesting some level of awareness or familiarity, possibly acquired in the womb.
With the help of new technologies like functional near-infrared spectroscopy, scientists can now study babies’ brains by measuring blood oxygen levels. This has led to fascinating insights, such as the discovery that babies at risk for autism show different brain responses to social cues compared to their peers. Such findings could pave the way for earlier detection of neurological differences.
Research has also revealed that even three-month-old infants may have a basic sense of numerosity. In experiments, babies showed signs of boredom when repeatedly shown images of four dots but became interested again when presented with an image containing eight dots. This suggests that babies might have an innate ability to perform simple mathematical assessments.
Another intriguing area of study is whether babies can make moral judgments. In one experiment, eight-month-old infants preferred a character that rewarded a helper over one that punished them. When a hindering character was introduced, the babies favored the punisher, indicating a possible instinctive sense that good behavior should be rewarded and bad behavior punished.
There are several popular beliefs about babies that don’t hold up under scrutiny. For example, some people claim that the shape of a pregnant woman’s belly can reveal the baby’s sex, with a high belly indicating a girl and a low belly indicating a boy. However, research has shown no correlation between abdomen shape and gender.
Similarly, the “Mozart effect” suggests that listening to classical music can make babies smarter. The original study was conducted on college students, not infants, and its findings cannot be generalized to babies. While music may have some minor positive effects, there’s no strong evidence that it enhances cognitive abilities in children.
Educational DVDs like “Baby Einstein” have also been marketed as tools to boost babies’ intelligence. However, studies have found no improvement in language acquisition among babies exposed to these videos compared to those who weren’t. In fact, infants who watched the content at a young age had lower language scores than those who didn’t.
Baby walkers are often advertised as aids to help babies learn to walk, but they can actually delay independent walking and pose safety risks. The American Academy of Pediatrics advises against their use for typically developing infants.

All newborns do is eat, cry, and create oceans of tears. However, that sentiment isn’t entirely accurate for several reasons. We’ll explore the surprisingly rich interior lives of babies shortly. One unexpected reason this idea is false is that newborns don’t actually cry tears at all. Most babies don’t shed tears in the first few weeks of their lives. The lacrimal glands generally start ramping up tear production around two weeks into a baby’s life, and it’s typical for visible tears not to be noticeable until weeks or even months after that.
By the way, if you’ve never heard the term “lacrimal glands” before, you might be surprised to learn that the tear ducts are not responsible for tear production. This is a common misconception.
Welcome to “Misconceptions.” I am your host, Justin Dodd. There’s a lot of misinformation out there about babies, and analyzing some of these misconceptions can shed light on humans of all ages. From anatomy to psychology to commerce, we can learn a lot about ourselves by identifying what we might have wrong about infants.
Many influential thinkers, from John Locke to David Hume, have proposed some version of the “tabula rasa” or blank slate theory of knowledge. Locke asked readers to think of the mind’s starting place as resembling white paper, void of all characters. While that was more a point of departure for an analysis of how we acquire knowledge than an actual proposal for how a baby’s mind functions, it’s fair to say that many of us view babies as essentially blank slates.
Recent developments have helped scientists explore what babies may know. For example, scientists like Robert Fantz realized they could use the time a baby spends looking at something as a rough indicator of interest or surprise. Four-day-old infants, for example, were shown to have a preference for the language their mother speaks. This suggests some sort of knowledge or awareness of what they’ve been exposed to, perhaps even in the womb.
Newer technologies like functional near-infrared spectroscopy allow scientists to analyze babies’ brains by measuring levels of blood oxygen in the brain. This technology has shown that four to six-month-old babies at risk for autism exhibit less brain response to social cues than a low-risk group of peers. Insights like that could lead to earlier detection of a range of neurological differences.
Studies have also indicated that even three-month-old infants may have a sense of numerosity. For example, when shown a sequence of images of four dots in various configurations, babies showed evidence of boredom but perked up when shown an image containing eight dots. Other studies suggest that babies can do a kind of rudimentary math.
Researchers have also explored whether babies can make moral judgments. In one experiment, eight-month-old babies preferred a character who rewarded a helper over one who punished him. In a different setup, when a hindering character was introduced, the babies preferred the punisher. This suggests they may have an instinctive sense that bad behavior should be punished and good behavior should be rewarded.
Now, let’s address a common belief: that a pregnant woman’s belly can reveal her child’s sex. Some say a high baby bulge indicates a girl while a low belly indicates a boy. This reasoning is based on folklore and doesn’t hold up to scrutiny. Research has shown no relationship between abdomen shape and gender.
Another popular belief is the “Mozart effect,” which suggests that listening to classical music makes babies smarter. However, the original study was conducted on college students, not babies, and the findings cannot be generalized to infants. While there may be some minor positive impacts from music, there’s no compelling evidence that it improves cognitive abilities in children.
Similarly, educational DVDs like “Baby Einstein” have been marketed as tools to make babies smarter. However, studies have shown no enhanced language acquisition among babies exposed to these videos compared to those who were not. In fact, infants who watched the content at a young age had lower language scores than those not exposed to the DVDs.
Lastly, baby walkers are often marketed as tools to help babies walk, but they can actually delay independent walking and pose safety risks. The American Academy of Pediatrics advocates against their use for typically developing infants.
