There is a mod out there, I believe I have seen it on mod the sims, that does take the social worker out of the game. Maybe you have that installed and don’t know it?
I don’t think i have that, because I can teleport the social worker, so she’s not removed. But what I think I have is a mod that lets you leave children and toddlers by themselves. Not sure why I installed it.
I decided to leave it in, and take care of the bbs myself.
