This mod allows you to change the pregnancy time to be longer or shorter than the default of three days.

The mod comes in 4 flavors. Choose your favorite:
1 day pregnancy (8 hour trimesters)
9 day pregnancy (3 day trimesters)
18 day pregnancy (6 day trimesters)
30 day pregenancy (10 day trimesters)

Install Instructions

1. Choose only ONE flavor of the mod. Extract the file into Documents/Electronic Arts/The Sims 4/Mods (or wherever you normally put mods)

2. In the mods folder, create an empty folder named "unpackedmod"

3. Open resource.cfg, and add the following line if it is not already there:
DirectoryFiles unpackedmod autoupdate


This mod overrides XML resource 03B33DDF 00000000 06F6554A25E46FD0 and will conflict with other mods using the same resource. This resource controls the length of pregnancy, as well as the chances for twins and triplets.

This should be compatible with AgonistAgent's "Babies for Everyone".

Love this mod, but seem to run into issues with aging. The pregnant sim (both times) has stopped aging during her pregnancy, and then resumes once she has had the baby. Just pointing it out, I can simply age her with a birthday cake if need be.

i love this since i hate the 3 day crap resulting in sims who can have like 20+ kids in 1 life span (i use the long life span, obviously). that many kids would be pretty ridiculous, so i chose the 30 day 1 for the closest to realistic i could get, however i noticed 1 thing: when my sim got pregnant: she would only age like 1 day each trimester, while her husband kept aging normally, so he's now like 20 days older than her, when they had been the same age at the start :o

I tried making a 280 day (9 months) version using the technique you mentioned and I am not getting anything near what it needs to be. Any ideas why?

I feel like the creator may have given up on this mod since i don't the problem being resolved, nor the creator even remarking about it. I hope someone tries to figure out the aging bug that this mod has.

I think it's because it overwrites the same thing I have the same problem. I guess you have to choose wich one you want to have

I've had this mod installed for quite some time and I was only having 1 kid per pregnancy even with both parents having the fertility treatment. I removed it and had 2 sets of twins. . Of course they came at the worst time possible. . Parents were living in a 1 bdrm house.
