Gender Neutral Term for Nieces and Nephews

Emily from Madison, Wisconsin, has three nieces and a nephew, and wonders if there’s a gender-neutral term for the group of them, in the same way cousins can designate one or two genders. German has the single word Geschwisterkind, meaning “a child of a brother or sister,” English doesn’t have a single established term for this. Some have proposed that English speakers use the word niblings, formed by analogy with siblings. Other suggestions include niephlings, nieflings, or nieblings. This is part of a complete episode.
