The Surprising Science Behind Being the Eldest Daughter
Raising as the eldest brother, the writer Y.L. Wolfe She often felt that the boundaries between her role and her mother’s role were unclear.
Once my youngest sibling arrived and I was nearly 11 years old, I felt an overwhelming sense of duty towards ensuring his well-being," Wolfe, who is the eldest among four siblings, shared with GudangMovies21. "I would often find myself sitting beside his crib watching him sleep just to ensure everything was alright.
It wasn't that I believed my mother lacked competence — rather, I felt we were both Responsible for the family at that stage of my life," she said. "It felt like I was truly their 'second mother' instead of just being an older sibling.
In other terms, Wolfe has an intimate understanding of “eldest daughter syndrome.” The internet is rife with thinkpieces regarding the challenges faced by eldest daughters tweets About how we — I should disclose my prejudice here — ought to organize unions: "Should you be the eldest sister, you could qualify for monetary reimbursement," One woman made a joke on Twitter, the platform previously called Twitter.
Although "eldest daughter syndrome" is a term from popular psychology — you won't see it officially recognized in the DSM-5 — recent research indicates that this quasi-diagnosis might have more scientific backing than was earlier believed.
A study led by researchers from UCLA has revealed In some cases, first-born daughters often develop more quickly. allowing them to assist their mother in raising their younger brothers and sisters.
The study revealed that an association exists between initial indicators of adrenal puberty appearing in first-born daughters and their mothers undergoing significant prenatal stress.
Why does age of adrenal puberty Changes such as acne and alterations in body hair occur during this stage, along with developments in brain function. It is thought that adrenal puberty processes promote social and cognitive transformations; essentially, these external physical modifications align with advancements in emotional maturity.
When facing difficult times and stress during pregnancy, it serves the mother's adaptive interests for her daughter to rapidly accelerate social maturation, according to Jennifer Hahn-Holbrook, one of the study's co-authors and an assistant professor of psychology at the University of California, Merced.
"It provides moms with an earlier 'helper at the nest,' which assists the females in ensuring their younger offspring survive in challenging conditions," she explained.
Significantly, adrenal puberty does not encompass breast growth or the start of menstruation in girls (nor testicle expansion in boys). According to the research, this stage makes girls mentally ready to look after their younger brothers and sisters without yet possessing the physical capability to bear children themselves, thus potentially reducing their focus on duties related to elder daughters.
Elder brothers appear to be excused from this sort of thing. parentification :The researchers did not obtain similar findings among sons or non-firstborn daughters.
"One potential explanation for why we did not observe this effect in first-born boys is that male offspring tend to contribute less frequently to hands-on child care compared to female offspring. As a result, mothers may have fewer reasons to accelerate the social puberty of their sons," Hahn-Holbrook clarified.
Moreover, she pointed out that previous studies indicate female puberty timing is more adaptable to early-life experiences compared to males.
The outcomes of this research, featured in the February edition Of Psychoneuroendocrinology (try saying that five times quickly — or just once) took quite some time: The researchers followed the families over a span of 15 years, starting from the prenatal phase through the children’s teenage years.
The researchers enlisted participants from two obstetrics clinics located in Southern California when the women were undergoing their standard first-trimester pregnancy checkups. Typically, these individuals were around 30 years old and expecting a single child rather than multiples like twins.
Approximately half of the participants were experiencing their initial pregnancy. These women did not smoke or use steroids, tobacco, alcohol, or any recreational drugs throughout their pregnancy. All of them were older than 18 years at the time.
During five distinct phases of pregnancy, the expectant mothers' stress, depression, and anxiety levels were evaluated and subsequently aggregated for analysis. To assess their depressive states, these women rated the accuracy of phrases like "I experienced feelings of loneliness." For gauging anxiety levels, participants indicated how frequently they encountered specific sensations, including feeling 'on edge.'
Among the children born to these mothers, 48% were girls and 52% were boys.
As the children grew older, separate measurements for adrenal and gonadal puberty were taken — including features such as body hair, alterations in skin appearance, increases in height or growth spurts, breast development, and the start of menstruation in girls, along with changes in voice and the emergence of facial hair in boys.
The research additionally assessed childhood adversities such as parental loss through death or separation due to divorce before the child reached five years old, along with the lack of a father figure and financial instabilities during the later stages between seven and nine years of age, all of which can be linked to earlier development or indications of puberty in young individuals.
Considering all factors, it was the oldest sisters who developed more quickly when their mothers went through significant prenatal stress.
Other research indicates that there might be certain late-life advantages for notably dutiful elder sisters: A 2014 study discovered that firstborn daughters benefit from these traits. most likely to succeed among all types of siblings, a 2012 study revealed that firstborns tend to be more prone to taking up leadership positions .
The observations hold valid for Wolfe, the mentioned author who expressed feeling akin to a second mother to her siblings during her upbringing.
I'm completely unsurprised by the findings of this study," Wolfe stated. "However, my personal experience differs somewhat—I underwent full puberty rather than just adrenarche at age 12, although I believe I also had an accelerated development of cognition.
The research also piques interest for an additional rationale: The results contribute to social scientists' expanding comprehension of fetal programming This intriguing field examines how various stresses, including emotional and environmental influences that women encounter during pregnancy, can impact their offspring for years following birth.
"This represents a unprecedented discovery and offers intriguing insights when viewed from an evolutionary perspective," stated Molly Fox, a UCLA anthropologist and also a co-author of the study, in a press statement.
During an interview with GudangMovies21, Fox elaborated further on the mechanisms of fetal programming.
"One intriguing hypothesis suggests that while you're still a fetus in your mother’s womb, you receive signals about what the world will be like, allowing your body to adaptively modify the stages of your lifecycle to best suit the conditions you anticipate encountering," she explained.
Fox and her fellow authors are thrilled that their research is now available for everyone to read, particularly since they have been closely tracking these families over an extended period. The timing of the publication coinciding with broader discussions around firstborn daughters has added extra excitement, especially for Fox, who herself grew up as a co-firstborn (she has a twin).
"As the eldest sibling, I believe it's a unique position within any family due to the opportunity for a close relationship with my mother and the ability to assist in caring for my younger brothers and sisters," she stated.
spoken like a true firstborn daughter.
