Hey, I've been having trouble with the pregnancy duration! No matter what number I put in to multiply the base game duration by, each trimester is always 14 days. I've tried deleting the mod and redownloading, changing households, terminating pregnancies and restarting them, yet nothing has worked. I'm at a loss and could really use your help please as I love the idea of this mod and really want it in my game !

Hi, how do you assign the base duration?

SiimplyJessica · September 25, 2026

so i just want to confirm here, i don't have to input any of the belly value numbers myself from the google doc? i just have to download this and the injectors and then make sure the pregnancy duration is set long enough in game to be able to see the progression, which is done on MCCC or WW?

That's right! The preset already has required values, you only edit them if you want it

This mod is LIFE-CHANGING!!!! It has always bothered me so much that sims' baby bellies change so drastically from one trimester to the next, especially the difference between 1st and 2nd trimester. This has made the game SOOOO much more enjoyable!! THANK YOU!!!!

Love that you included belly size guides for those of us already using LIttleMsSam's mod. Thanks for putting in the effort to make it compatible with so many mods!

SonozakiSisters · August 22, 2026

You're welcome! It was essential, as I understand many people play with such mods, including myself

I have a mod that makes the max belly size 200% (100% is way too small for twins and triplets) could you make a version with the max size able to go to 200%? I loved your other pregnancy mod and was able to make the adjustment to the .package but I’m not very good writing .t4scripts

S
SonozakiSisters · August 16, 2026

Hi, it's impossible. You can "set" whatever value you want, but the size is strictly limited by the game code: self._pregnancy_progress = clamp(0, value, 1) if value is not None else None The function clump forces the value to be no lees than 0 and no bigger than 1 And even if it wasn't such function, any game sliders can't be bigger than 1 anyway. The pregnancy progress operates the sliders, so it's not possible on any code level

Just downloaded it. I use RPO so do I keep the EA injector that's in the zip folder or only use the RPO injector?

S
SonozakiSisters · August 2, 2026

You should keep both injectors
