The Neuroscience behind the ‘Parenting Paradox’ of Happiness
Separate brain processes cope with moment-to-moment versus big-picture experiences, which helps explain how parenting both increases and decreases aspects of well-being

Deciding whether to have kids can be one of the most momentous decisions a person makes. Countless factors can sway this choice. How will it affect your finances, your relationships or your career? Are you feeling pressure from your family or community? But one of the simplest, most personal considerations is whether, and how, having a child will affect a person’s quality of life.
Here, psychologists studying well-being have encountered what’s sometimes called the “parenting paradox”: parents report lower mood and more stress and depression in their daily lives than adults without children; yet parents also tend to report higher life satisfaction in general. How do we make sense of this contradiction?
My colleagues and I have conducted research that can help us answer that question—and, along the way, highlight the complexity of what makes for a good life. I’m an emotion neuroscientist by training, and I want to use brain science to understand the messy and complicated feelings that people experience in modern life. Feelings such as bittersweetness in reminiscences about an ex, simultaneous excitement and fear before a performance or ambivalence about a big life change are not easily quantified in the positive-negative scales scientists use in research—yet they can tell us a lot about how we process emotion when it matters the most. During my postdoctoral training, I worked at the University of Southern California in a laboratory focused on the parenting brain. That team has been following a group of first-time fathers through their partners’ pregnancy and their development as parents. I realized that studying these new dads over time would give me a chance to investigate how parenting relates to a meaningful life and what occurs in the brain as people’s life changes.

Focusing on “meaning in life” allowed me to study an aspect of well-being that transcends daily stressors—because parenthood is famously stressful. Unfortunately, I cannot tell you what the meaning of life is, but in psychology, it’s measured using people’s subjective reports that their life is coherent and has an overarching purpose. This abstract feeling of “things make sense” has been shown to be a powerful predictor of overall well-being and mental health, even when people are going through objectively difficult times. People who feel greater meaning in life are often more resilient against larger mental health problems that might arise from adverse events such as global pandemics, severe disease and war trauma, research has shown.
In our study, my colleagues and I predicted that most new fathers would report an increase in meaning about six months after the birth of their first child compared with their reports during their partner’s pregnancy. Instead, in 88 fathers, we found a roughly even split in those whose sense of meaning increased or decreased. Clearly, only about half felt that life was more purposeful because they had become a parent. But that was just the first of several important insights.
Of our participants, 35 agreed to be scanned with a form of brain imaging called functional magnetic resonance imaging (fMRI) both before and after the birth of their child. We used these brain scans to calculate how in sync each part of the brain was with the rest. For people with strong functional connectivity, when activity increases in one area, it also ramps up in the rest of the brain. Other scientists have conducted fMRI studies with hundreds of people and found that this measure is related to increased meaning in life, potentially because greater connectivity in the temporal lobe and other emotion-related regions of the brain allows for better integration of emotional, self-oriented and abstract thinking.
We wondered if this connectivity changes during a major life event such as having a child and, if so, whether this related to one’s sense of meaning and purpose. By comparing scans before and after our participants became fathers and reviewing people’s reports about their experiences, we modeled whether functional changes in different parts of someone’s brain predicted either their sense of meaning in life or their (positive or negative) feelings about parenting.
People with positive parenting feelings exhibited more connectivity changes in parts of the brain that are important for self-control (the middle frontal gyrus) and empathy (the supramarginal gyrus). Those with more negative parenting feelings showed changes in the sensory cortex and cerebellum, which may relate to hyperemotional sensitivity to sensory information. (If a baby’s cry always triggers a hyperstressful response, parenting is going to be very difficult.) Meanwhile fathers who maintained or increased their sense of meaning showed increased brain connectivity in regions such as the insular cortex and temporal pole. These areas are crucial for integrating a person’s emotions and senses with their broader sense of identity, suggesting that fathers who more effectively engage in this contextualizing process during this new life stage tend to flourish.
With these differences, we can start to think more deeply about the parenting paradox. A father might feel overwhelmed by sleepless nights yet still contextualize this as part of a meaningful existence. In other words, the challenging emotions people deal with in the short term can become independent from a long-term sense of satisfaction, potentially because separate brain processes underlie the two. Without this cognitive translation, day-to-day stressors may dictate overall sense of well-being, or the mix and shifts between positive and negative parts of parenting may make life seem overall incoherent for these fathers. Integrative regions such as the temporal poles and insular cortex allow both positive and negative events to fit together, potentially into a framework that facilitates long-term well-being.
This distinction fits into a larger body of research about how people build what scientists call a “coherent self-narrative,” or the story individuals tell about themselves. For example, past research has found that simply viewing oneself as being on a “hero’s journey” increases resilience. When someone can situate their feelings in a story that makes sense to them, it may not matter whether a particular situation is positive or negative so long as it fits into their longer-term goals. It seems the answer to whether parenthood makes people happier therefore has less to do with the children themselves (sorry, kids) and more to do with whether that goal of parenthood aligns with the individual person.
A recent analysis of a dataset that followed German adults from 1984 to 2021 actually found no average difference in the well-being of middle-aged adults with or without kids, though there was more variability for parents than there was for nonparents. What was really interesting, however, were the results for young adults. The most important factor for understanding their well-being was not whether they had kids but the importance they placed on the goal of having kids. Childless young adults who placed high importance on having kids experienced lower life satisfaction as they grew older—if their perceived importance of this goal remained high as they aged.
But those were a minority. Most of those child-free adults deemphasized that goal as they aged, and their happiness was then no different from adults with kids. This finding might highlight the takeaway for our study’s dads and for those questioning whether they want children: meaning can be created regardless of the choice made. The adaptive brain can shift journeys, reimagine stories and help people thrive, even when life throws us a curveball—or a screaming infant at two in the morning.
