"The Truth About 'Eldest Daughter Syndrome': Surprising Findings from a New Study"

A new study suggests that "eldest daughter syndrome" may have scientific backing, as first-born daughters tend to mature earlier, potentially due to their mothers experiencing high levels of prenatal stress. This early maturation may enable them to help rear younger siblings. The study tracked families for 15 years and found a correlation between prenatal stress and early signs of adrenal puberty in first-born daughters. The findings contribute to the understanding of fetal programming and shed light on the long-term effects of maternal stress during pregnancy on children's development.
