siblinghood
Brother-sister bond status
Siblinghood is the state or condition of being siblings—brothers or sisters to one another.
The word captures both the biological relationship and the broader experience of growing up together: The bond of siblinghood shaped who they became.
It can extend to non-biological relationships that feel sibling-like: a siblinghood forged in foster care.
