I'm sorry. ; ~ ;
Being an aunt can only happen if your siblings have a child.
If your cousins have a child, they become your second cousin.
And if your second cousins have a child, they're your third cousins.
And so on and so forth.
Of course, your cousins can always have their baby grow up calling you Aunt.
Especially if it's normal within your family for them to do that.
But it'll be confusing to the rest of the world if you tell them they're your cousins baby.
