I disagree that there hasn't been enough feedback about the babies. There's been plenty.
I wish that EA could send the furniture babies back to the year 2000, where they came from. It's 2018 and there's so much more that could be done with the infant life stage.
I know that there were lots of complaints about cold, naked babies, left to fend for themselves in the snow. But couldn't that problem be solved by creating other docking stations for the babies besides the bassinet? Changing tables, play mats, infant seats, strollers, play pens, swings, bouncy chairs, the middle of a double bed... All of those could be places to "park" the baby when a Sim isn't interacting with it.
Real life babies are so much fun. EA, you've captured some of the magic of toddlers. Please, turn your attention to the babies so that they can be a part of their Sim families, too -- like they used to be.
Edited to add: I also didn't mind the rancid diapers and fuming green bottles all over the place. Details like that are what makes TS2 the pinnacle of the series, to this day. When Sims had babies in the house, it was easy to tell.
Babies are a lot of work and the house should look like it with all kinds of baby paraphernalia all over the place. I would love fully kitted out nurseries, plus bottles, bottle warmers, clothes, toys... No more Sims pulling bottles out of their pants. No more disappearing diapers. Bring the details back. Please.
