Therapists warn of a quiet but widespread challenge for firstborn girls: an overwhelming sense of over-responsibility that erodes happiness and well-being. Known in some circles as “eldest daughter syndrome,” this collection of expectations uniquely affects firstborns and shapes long-term mental health. The idea resonates in Thai families, where traditions often place heavy duties on the eldest child.
In Thai society, family structure and filial duty are deeply valued. Eldest daughters often serve as the emotional backbone of the household. They are expected to care for younger siblings, coordinate family activities, and handle numerous unseen tasks that keep daily life running smoothly. When these roles start early, they can foster perfectionism, self-criticism, and burnout over time.
Some therapists point to research suggesting firstborn daughters mature more quickly due to prenatal stress experienced by mothers. This early maturation can lead to “parentification,” where daughters assume mini-adult roles and internalize the belief that they must be the person no one needs to worry about. The impact extends beyond home life, shaping behavior at work, in friendships, and within other social settings.
The pattern is reinforced by gender expectations. In many households, especially within traditional family dynamics, eldest daughters are seen as partners to mothers in managing the family, sometimes compensating for less-involved fathers. This can deprive girls of a carefree childhood and entrench a lifelong cycle of self-imposed demands and relentless self-criticism.
The emotional toll is real. When adults carry the weight of responsibilities they could not realistically manage as children, they often feel inadequate. As one therapist notes, placing adult tasks on children sets them up to feel like they’re failing because they aren’t equipped for those roles. The result is a persistent drive to do more, seeking an elusive sense of accomplishment.
These dynamics collide with cultural expectations in Thailand, where caregiving roles for women are commonly emphasized. Eldest daughters may be urged to oversee household rituals or support aging relatives, reinforcing perfectionism and the belief that self-worth derives from constant dependability. Educators in Bangkok report that many eldest daughters shoulder extra academic and extracurricular burdens to “set a good example,” frequently accompanied by heightened anxiety.
Experts recommend practical steps to curb these pressures. The first is awareness—recognizing the “eldest daughter” role and distinguishing what is helpful from what is harmful. Boundaries are essential: sharing duties, encouraging siblings to contribute, and learning to say no when overwhelmed. Self-compassion matters, too: permit mistakes, slow the pace, and reclaim opportunities for joy that were missed in childhood.
Therapists also advocate inner-child work. Giving oneself the experiences denied in youth—such as attending a friend’s birthday party or enjoying a favorite activity—can be a healing act. This approach helps dismantle rigid perfectionism and builds resilience.
Beyond family, seeking support through friendships, women’s circles, faith groups, or mental health communities can provide safe spaces for vulnerability. In Thailand, these networks can offer practical help and emotional relief without burdening family members.
A key shift is rejecting the old creed that “If I’m not hard on myself, I’m not safe.” Healing involves kindness toward oneself, setting reasonable expectations, and embracing rest. As a leading somatic therapist emphasizes, even on busy days, choosing gentleness can reduce fatigue and improve overall well-being.
Awareness and dialogue about eldest daughter pressures can help reduce stigma and foster healthier norms in schools, workplaces, and homes. Schools and mental health professionals can develop programs that acknowledge the hidden burdens carried by eldest daughters and promote equitable family dynamics. Campaigns encouraging parents to share responsibilities more widely can reshape longstanding cultural expectations.
For now, Thai readers can take practical steps: start open conversations about family duties, redistribute chores, and support eldest daughters in prioritizing self-care. Eldest daughters should practice gentle boundary-setting, seek supportive communities, and allow themselves moments of joy. By moving away from perfectionism, they can regain balance and happiness at every life stage.
