A new analysis of family dynamics and parental stress has upended common assumptions about the optimal number of children to raise, revealing that, counterintuitively, four may be the magic number for the least stressful parenting experience, according to a widely shared 2013 survey by TODAY Parents. This finding, echoed by research and commentary from mental health professionals, is especially relevant in Thailand, where changing family structures, economic pressures, and social expectations are reframing the debate on ideal family size.
The belief that more children means more headaches for parents has long guided reproductive decisions globally, including in Thailand, where birth rates are at historic lows and small families are becoming the norm. But the TODAY survey of over 7,000 mothers in the United States revealed a significant twist: Moms of three children report notably higher stress than those with one, two, or even four or more children. In fact, parents with four or more children self-reported lower stress levels—a phenomenon dubbed “The Duggar Effect.” The average mother in the survey rated her daily stress at an 8.5 out of 10, painting a vivid picture of contemporary parenting pressures (TODAY.com).
What drives this unexpected finding? According to a psychiatrist interviewed for the report, once parents reach four children, the relentless pursuit of parental perfectionism fades. “There’s just not enough space in your head for perfectionism when you get to four or more kids,” explained the psychiatrist, herself a mother of four. The result is a shift from micromanagement to “survival mode,” where parents focus on practicalities rather than unrealistic societal ideals. A significant majority—75%—of mothers surveyed said their greatest source of stress is their own pressure to be perfect, not external judgments. Financial strain, work-life imbalance, and maintaining personal wellbeing also ranked high among stressors, but the internal drive for perfection created a self-perpetuating cycle of anxiety and guilt (YourTango).
This insight is highly relevant for Thai families. Although recent government data and research from institutions such as PIER show that the average number of children per Thai family has plummeted—from more than six in the 1960s to less than two today (Nation Thailand), PIER), the cultural value of large families still subtly persists, especially in rural areas. Yet, urbanization, the rising cost of living, and modern parenting ideals are steering many toward smaller families, often out of fear that more children will translate directly into more stress and less economic security.
However, the U.S. survey’s findings defy this linear logic. For families with three children, parents often report feeling “outnumbered” and overwhelmed—a transition that brings chaos as the number of dependents outpaces the hands available to manage them. According to another expert quoted in the TODAY report, “Going from one to two [kids] was an easy, breezy transition. Two to three, everything was turned upside down.” In contrast, with four or more children, parents become more relaxed and less consumed by perfection. They instead focus on flexible routines and pragmatic parenting, a mindset shift that paradoxically lightens the emotional load (TODAY.com).
This phenomenon may also be linked to what psychologists term the “intensive mothering ideal,” a concept that has strengthened since the late 20th century. Intensive mothering, as outlined in a briefing by a psychologist at Ohio State University, dictates that mothers must devote extreme time, emotional energy, and expert-guided attention to their children’s development—pressures that are exacerbated in smaller or nuclear family settings. The guilt and fatigue associated with falling short in this pursuit have contributed to both lower birth rates and higher stress among modern mothers (YourTango).
In Thailand, this trend deserves close scrutiny. Thai parents are increasingly exposed to intensive parenting norms through social media and expert advice, borrowing from Western notions even as traditional support mechanisms—such as extended families—are dwindling in urban centers. Rapid social change, declining fertility, and increased female workforce participation create new pressures reminiscent of those described in the U.S. survey. Yet, as the Thai family shrinks, many parents still struggle with the burden of high parental expectations, echoing global trends.
Stress among parents, regardless of family size, is no trivial matter. The TODAY survey found that 60% of mothers were most stressed by “lack of time to do everything that needs to get done,” while 72% reported anxiety about how stressed they were—a recursive worry that compounds the difficulty of parenting in today’s fast-paced society (TODAY.com). These statistics resonate in Thailand, where working mothers and fathers often juggle employment, household duties, and childcare with little external assistance.
Culturally, the expectation for Thai mothers to embody self-sacrifice remains strong, even as society modernizes. Research on Thai families points out that mothers still shoulder primary responsibility for both emotional care and practical management of the home, a reality mirrored by survey results in the United States (PMC). Yet, the mental health consequences of this “supermom” syndrome are rarely openly discussed in local media, despite evidence of increasing parental burnout and emotional distress among Thai women.
What does this mean for the future of Thai families? As birth rates continue to drop—now among the lowest in Southeast Asia—Thai society faces a complex calculus: smaller families may ease some economic and logistical burdens, but may not guarantee happier or less stressed parents. The “least stressful” family size, according to research, may in fact be somewhat larger, aligned with the flexibility and confidence that come with relinquishing perfectionist ideals. For policymakers, educators, and healthcare providers, this suggests the urgent need to reframe parent education away from unattainable standards and toward support for all family sizes, with an emphasis on parental wellbeing.
Practical recommendations for Thai families emerge clearly from this body of research. First, parents should feel empowered to seek social support—whether from extended family, community organizations, or formal childcare, especially as the loss of large traditional households leaves many nuclear families isolated in cities. Second, both mothers and fathers should consciously challenge the myth of parenting perfection, embracing imperfection as not only normal but beneficial for family harmony. Parenting workshops and community outreach, spearheaded by governmental or non-profit organizations, should focus on strategies to reduce guilt and foster resilience—such as mindfulness, time management, and realistic self-care routines, as urged by the experts in the U.S. study.
For mothers feeling overwhelmed, the psychiatrist who contributed to the TODAY survey recommends a practical daily exercise: divide your day into a “reality pie chart” and a “wish pie chart.” Find one desirable activity missing from your real day and make a conscious effort to include it, even briefly. In Thailand, where time poverty is widespread among parents, such incremental changes can help combat chronic stress and improve overall family wellbeing.
As the debate around fertility, family size, and work-life balance intensifies in Thai policymaking and societal discourse, this research serves as a reminder that the relationship between number of children and parental stress is non-linear and culture-dependent. The key, say experts, lies less in the size of the family than in the willingness of parents, communities, and society to adapt expectations and provide meaningful, culturally sensitive support.
For Thai parents, the message is clear: more children do not necessarily mean more stress—and sometimes, giving up on perfection and embracing life’s messiness can turn the challenges of parenthood into genuine joy. As the country grapples with demographic shifts and evolving social norms, recognizing and addressing parental stress—not just counting children—may be the vital ingredient for building resilient, happy families in modern Thailand.
