sibling's

Belonging to kin

Sibling's is the possessive form of sibling, indicating something belonging to or associated with a brother or sister: my sibling's apartment, her sibling's opinion.

The word sibling itself is somewhat clinical, more common in formal or medical contexts than in everyday speech, where people typically say my brother's or my sister's.
