Are they ever going to update babies?

I doubt it. People have been complaining for 7 years, and nothing has been done. I’ve given up.
They have time to give us things most people don’t want (Journey to Batuu, Scenarios,etc.), but not things we’ve been asking about for years. They keep saying “we hear you”, but nothing happens.
Maxis/EA have earplugs and won’t listen.

I hear you on that. My last hope is that they’ll update babies if they release a generations pack.

I hope they do come but it's been 7 years now so maybe they will never come. As with cars, it's possible those will never come too.

I don't have much hope for that. Mostly because it would probably require them to remove the existing babies from the game and replace them with new ones that can move around, which would break saves.

I don't think they have said that they want to update babies either, apart from the "we know what the community wants" and "we are listening" when asked about it and I'm not sure if that means much after 7 years.

It would be easier for them to add minor updates to babies but major to other life states, like teen age or a more distinct young adult age and better adult. I hope that this changes will come in an *eventual *future Generations pack

I personally am inclined to believe that "updated babies" will never come. Not true sims-like babies that can be created in CAS.

I do think it might be possible for them to update them to be tied to other objects, like a swing, play mat, changing table, etc.

It could be similar to how chairs "snap" to slots at dining tables or desks, etc and the animations still work regardless of what object the chair is snapped to. Babies could be moved away from the crib and snapped to a new object. But of course, these would also require different animations (sitting up for a swing, laying on tummy for floor mat time, etc).

Of course, I'm not sure how this could be done in "live mode" since we can't move chairs around in live mode unless they worked like deco slots like the ones that sims use to set down books and dirty plates, empty glasses, etc. But then again you'd have the community up in outrage the first time the sims placed the baby down on an inappropriate slot (like on a grill or bookcase, fireplace, etc).

But, I'm also not confident the teams feels like it's a priority. I know they can monitor playing styles and statistics from game play sessions. Maybe they have noticed a trend of the majority of players skipping over this life stage. There's a lot of people who state they immediately age babies up, now I'm not sure if it's because they're kinda pointless the way they are, or they just don't enjoy that type of game play and babies are just an unpleasant step to get to more interesting life stages.

But I do hope they improve them in some way before TS4 ends, just for those people who do enjoy babies.

I have been waiting for updated babies for a long time. And they did say they heard us on that one. I think more people would play babies if they were updated. There are quite a few us us out there that play with aging turned off most of the time. If there were real babies, I would have my sims have them more often.

If they had clothing ( they do have some knitted outfits ), a changing table, and several bits of clutter for a nursery, cribs, a playmat, a swing, a blanket you can put on the floor or sofa, a baby bath ( or sink bath), sims being able to sit while they nurse babies or feed a bottle to babies ( the rocking chair would be great for that ), a snuggly and a stroller or baby buggy, and sims could take them off the lot with them. I think they would become much more popular. Heck I’d buy a game pack made for babies ( and hopefully toddlers ). I’d also buy kits for clothes and stuff packs for babies as well. I think EA would really miss out on a bundle of money if they didn’t update them. Also I think some people would be a bit less likely to buy Sims 5 for fear that babies might be the same as they are in sims 4. As it is, until people know there will be better babies for sure before they come out I doubt they will preorder Sims 5. If they want to keep a lot of people that play this game, and pull them into playing a sims 5 game that has online options, I think they are going to have to show a lot of sandbox players that the play alone game is going to be much better than 4 started off with, cause it looks like they are going to have some competition.

I do think some sort of Baby update is in the works. I just hope that whatever it is, it doesn't disrupt my play too much. (I don't age babies up right away and don't want to, but I also don't really care if they ever free the babies.)

No, I don't think they will at this point.

I'm positive that they're working on updating babies.
