You are that baby’s first cousin once removed.

Quick answer

• If your cousin has a baby, that child is your first cousin once removed.
• “First cousin” = you and your cousin share grandparents.
• “Once removed” = there’s a one‑generation gap between you and the baby.

Socially, a lot of families ignore the technical term and just use “aunt,” “uncle,” or “cousin,” especially if you’re very close in age to the baby’s parent or play a big role in the child’s life.
