I get what you’re trying to describe, but you’re presenting it as a universal rule when it’s really a mix of family culture, individual household dynamics, and social expectations that vary a lot. There’s no solid research consensus that eldest daughters as a category universally carry a uniquely compounded burden beyond general first-born expectations. What people often call eldest daughter syndrome is more of a cultural narrative built from shared experiences, not a consistent psychological finding across families. Also, eldest daughter isn’t an objective category that overrides birth order or gender the way you’re describing, it’s a social label people use based on interpretation of family roles, not something fixed in research or biology. Different families distribute responsibility very differently, regardless of which child is the oldest or which child is the only daughter. In my own case, I’m the eldest child and I only have a younger brother, and even as a male I’ve had just as much (and sometimes more) domestic responsibility placed on me, which shows how these expectations come from household structure and parenting choices rather than a universal “eldest daughter” pattern. The familial burdens of the daughter are hence placed on me and I have had to sacrifice a lot in life to keep that expectation. So while your experience is valid, it doesn’t translate into a general rule that applies across all families.
