33 Risky Woohoo & Try For Baby Chances

In The Sims 4, Sims know what they're getting in for when they decide to WooHoo. In real life, people do not share this luxury. Add some realism and surprise back to the game by downloading the Risky WooHoo & Try For Baby Chances mod.

Players will need to be mindful while messing around with their partners. Trying for a baby won't be a straightforward process anymore either, with everything from a Sim's mood to their traits governing their current rate of fertility. A high rate of fertility isn't necessarily a good thing either, since this can lead to unwanted pregnancies more often than not.

For Sims With Extreme Baby Fever

While the game already has a trait for Sims who are family-oriented, this trait just doesn't seem to focus enough on wanting more children or babies. After all, some are eternally in a constant baby fever mode and just can't get enough of the parent lifestyle.

That's where the Baby Maker Trait mod by Kialauna steps in and introduces a brand new custom trait called BabyMachine. Sims with this trait are often in a flirty mood and will want to seduce those around them to try for a baby. Moreover, they also get a boost when it comes to the Charisma skill, so they can better find romantic partners.

The Moment Of Surprise And Suspense

Players will no longer be able to just know from specific cues if their Sim is pregnant, such as certain idle animations like thought bubbles with baby items or appearing nauseous. This adds a lot of excitement and anticipation to gameplay, and it's also realistic in the sense that pregnancy isn't always easy or straightforward to detect.

30 Instant Morning Sickness

Not at all pregnancies are obvious. In real life, surprises take place all the time, and it can make for really great storytelling to have that same aspect of surprise in a game as well. In past Sims games, this was very much the case, as there was no option to take a pregnancy test.

The Instant Morning Sickness pregnancy mod by PolarBearSims ensures a Sim doesn't get a moodlet before experiencing morning sickness, which essentially spoils players with the surprise of what's happening. Whether they have food poisoning or they're pregnant, only time or a pregnancy test will tell.

29 No Pregnancy Spoilers

No Hints, No Spoilers, Just Surprises

No Pregnancy Spoilers mod

Building on the idea of maintaining suspense during pregnancy gameplay, the No Pregnancy Spoilers mod takes things a step further. Unlike the Instant Morning Sickness mod, which removes moodlets to keep the news under wraps, this mod eliminates the "Throw Up" interaction from toilets entirely.

By doing so, it prevents players from accidentally discovering their Sims are pregnant before they officially find out. This mod is perfect for those who love a good surprise and want to experience pregnancy reveals organically, just as their Sims would. Simple yet effective, it ensures that the big moment remains exciting and unexpected.

It's a creative way to make every pregnancy reveal more memorable and unique.

Players can use these items to create immersive storytelling moments, from preparing for the baby’s arrival to taking care of postpartum needs. With its thoughtful touches and wide range of objects, this mod pack celebrates the complexities of pregnancy in a way that feels heartfelt and engaging.

26 Pregnancy Overhaul

Pregnancy definitely doesn't look the same on everyone, and the way EA designed it seems a bit cartoonish at times. LittleMsSam's pregnancy mod for The Sims 4, Pregnancy Overhaul, introduces a much more toned-down version of a pregnant Sim's appearance and its range of animations.

A pregnant Sim will no longer have a massive belly that might seem exaggerated. Moreover, a Sim will now walk normally regardless of being pregnant. Plus, while a Sim is still in their first or second trimester, they can participate in more physical activities, namely jogging, and yoga.

25 Pregnancy Weight Gain

A More Realistic Post-Pregnancy Journey

If players still don't think their pregnant Sims have realistic weight fluctuations, the Pregnancy Weight Gain mod can solve their problems. Unlike the base game, where Sims snap back to their pre-pregnancy physique immediately after giving birth, this mod introduces gradual weight gain throughout each trimester.

Factors such as age, lifestyle, traits, and mood influence the likelihood and extent of this change, creating unique experiences for each Sim. After delivery, Sims retain their pregnancy weight until they naturally lose it through exercise or lifestyle adjustments. This small yet impactful mod reflects the physical changes that accompany pregnancy, perfect for those who value realism and nuanced pregnancy playthroughs.
