Your cousin’s kids are your first cousins once removed in correct family- relationship terms.

Simple answer

  • Your cousin’s child → your first cousin once removed.
  • You are also their first cousin once removed (the term works both ways).
  • In everyday speech, many people just say “my cousin’s kids” or even treat them like nieces/nephews, especially if you are very close.

Why “once removed”?

  • “Removed” shows a generation gap between cousins. “Once removed” = one generation apart.
  • You and your cousin are the same generation; their child is one generation below you, so that child is your first cousin once removed.

What are they to your kids?

  • Your children and your cousin’s children are second cousins to each other, because they are in the same generation and share great‑grandparents.

Cultural / informal usage

  • In English, the technical term is first cousin once removed , but informally many families just say “cousin” or “niece/nephew” depending on closeness.
  • Some other languages use a word closer to “second nephew/niece” for this relationship, which adds to the confusion when translating.
