Kissy elves are neat.

Double-checking my understanding: in this universe, any gender can reproduce with any other gender, and d/d and e/e pairings can reproduce, but not m/m or f/f?

That's what I've got, yup.

Are there words for elf and dwarf children? Obviously in universe there would be but for use in discussion? Also, this is a good setting idea!
(If you decide to go back the route of making all the genders have their own complications, perhaps dwarves could have like, eggs/geodes or something that have to sit underground until they hatch? I do not have cool ideas for men or women because they are not conveniently archetypally themed with elements the way elves and dwarves are.)

Geode eggs are a cool thematic idea for some kind of dwarves!

I don't yet have names for elf or dwarf children, and I'm not aware of any in the literature like "fauntling" for little hobbits. My imagination suggests "beardling" for a dwarf child but I'm not sold on it.

Beardling sounds like teenager-equivalent to me.

It has that sound to it, yeah. So I don't have a good word for a dwarf child in general.

If dwarves and elves were rock and tree themed, maybe pebbles and saplings, but since they're not...

Fluffs/Floofs for smol dwarves, since they have beards? But "boy" and "girl" don't really refer to sex-characteristics so that might be weird.
Possibly-excessive conlanging, just picking out-of-universe names and saying they translate to something less weird, or continuing to try for a word?

...Would it be incorrect to call them gnomes and halflings? I'm tempted.

xD

Gnomes feels better than halflings to me.

Dwerrings, dwerlings, shards, roughs, ores?
