(Great name BTW.)
I’m not quite sure the solution but I found the babies to be too loud and distracting. I think if every account had a color and emoji it wouldn’t be as distracting, but I also might hate that more.
It might just be the yellow of it all, if it were black and white that might make it better, but that’s not how emoji works so I’m out of ideas.
I do think it’s a neat feature, but I had to turn it off. Figured by posting here other folks might have ideas.
Edit: Android PWA 1.14.0
The new version of Voyager has an option to put baby emojis next to new accounts. I think they are saying they are getting distracted by that.
