So if my cousin has a baby, how is that baby related to me? In my head, I call them “nieces” and “nephews,” though I know that’s not accurate. Out loud, I say “my cousins’ kids” so that others don’t think that my 20-year-old brother is a baby daddy.
Are they second cousins? Cousins once removed?
I don’t actually care. All I know is that they are adorable, and I have another one as of late last night/ early this morning. Her name is Gianna, Gia for short, and I cannot wait to meet her.

Ooh, just looked it up, and your cousin’s child is your first cousin, once removed.
Your child and your cousin’s child will be second cousins. 🙂
