Yes!
Vivi is a mom, she has a daughter named Mia!
There's isn't much lore for Mia yet, besides the fact that she's an adorable bundle of fluff that is curious about everything and loves fighting her vaporeon plushie (She's destroyed 4 now). Her curiosity makes her a bit of a trouble maker and there was a while shortly after she was hatched where she was afraid of Kai, but that's about it for her lore. But who knows what her future holds...
There's no real art of her yet besides two little emotes I made of her for my discord. But she'll probably have some in the future!
