I guess if upstead babies never exist on the show, that's one less thing for the writers to mess up. They can exist in our heads and everything works out!
I imagine they would have a little girl called Zoe. It is Greek but still common. It is also one of my favorite names and the name of my first doll so I might be biased. Maybe they would have a boy called Theodore (Theo). I have always told myself upstead and I would have similar taste in names lol.
That's one way to look at it!
Kids definitely seem like something that will only exist in fanon. It's so fun to see what people think Jay and Hailey would name a baby. Zoe and Theo are cute! I have always thought they'd stay simple and classic. Basically anything on the current top ten name list- Olivia/Emma/Ava/Sophia/Mia or Liam/Noah/Oliver/Lucas- would also be fully believable to me.
My current favorite names are Lucy, Avery, or Eden for a girl and Ellis or William (ha!) for a boy. I'm not sure they'd jive with some of mine too easily.
Also- props on having an actual, respectable name for your first doll! Mine was Blue Baby. It wasn't even trendy or unique like Beyonce's Blue. It was Blue Baby, her full and given name.
