There are many things I think the game still needs, but as a family/generations player I hope they overhaul babies completely and make them a Sim instead of a simple object no one wants to be bothered with.
Gives them also a good reason to bring back the Changing table for example, but there are so many things they can do with babies to make them better..
I would also love to see ''proper teens'' (that means for example they make them shorter, which probably will never happen because animations reworking blablabla). And more stuff for the Elder life stage to enjoy. Canes for example.
In general I think they have to flesh out a lot of the life stages more.
But I know, that's probably not going to be it anyway.
