@Whirlaround Actually... it would be kinda cool if the adult sims could relive life again. Like age them down even younger.

Wow discovered this late thanks! gonna try

I'm so happy for this mod! Finally I aged up all the npc babies (33!) to toddler and now they can play at playgrounds with my playable toddlers.

I'm glad it worked out for you! :-)

Yay! I was looking for something like this! I like playing with aging off but then when my kids age up manually their friends don't age up with them, this solves it!

Cool! Hope it continues to work for you.

Dangit. Why am I *JUST* finding this mod? Could have saved me a ton of hours running around trying to age babies! THANKS!

The mod worked until 1.86. With version 1.87 began to cause LE.

Still works for me.

Hi! are you planning on updating this for the infant update? I absolutely love this mod!

That mod is OUTDATED. Electronic Arts has updated Sims 4. That mod dates back to 2022.

Since Whirlaround hasn't been seen in a while, I've taken the liberty of attempting to update this mod since I use it quite heavily. After this, I will only try to fix something if it is broken now or breaks in the future. Should Whirlaround return and update the mod, I'll remove my version.

Added commands:
list_infants
age_up_all infants

Removed:
There was something in the old code, "sim.relationship_tracker.update_bits_on_age_up(sim.age)", that appears to have been removed by EA in 1.96. I don't know what it did, and I don't know what replaced it. I hope it wasn't important.

Ah thanks for that update. His old out of date mod was driving me UP the wall ><

Thanks you're awesome!

Thank you very much! When my Sims have babies with a Sim that's not in the household, until the baby ages to infant, I can't even see it. This mod is fundamental!

Thank you for updating! This mod has always been essential and it's great to see it updated.

I can't see the button, 'getting older', or, 'getting younger'...

Is there anyone among you who can help me?

Are you using the updated version linked in comments here?

HI! I just find this mod, and this is a need in this game !!!
I hope its still work with 1.108 game Lovestruck... But for now i cant download it, i have this

Uh oh!
There seems to have been a slight problem with the database.
This error has been logged and our technical team will look at it as soon as we can.

We apologise for any inconvenience.

Is the updated version still working with the new patch?

Thanks so much for updating this mod a while ago, I am happy to report whirlaround_AgeUpOrDownAll_1.96.zip (posted in a comment above) is still working in July 2025!

Tested my updated version (link on my previous post) with the August 19th (1.117) patch. Was able to load households. Tested age_up, age_down, age_up_all, age_down_all, and the various list_ commands. All seemed fine.

Reminder that newborns are still referred to as babies when using this script.

If you find any issues, let me know.
