How do you speed up pregnancy in The Sims 4? If you’ve ever watched your Sim waddle around for what feels like an eternity and wondered if there’s a way to bring that baby into the Sims world a little sooner, you’re in the right place. The simple answer: yes, you can dramatically fast-forward pregnancy in The Sims 4 using a handful of powerful cheats. Whether you want to skip straight to labor, choose the number of babies, or even pick the baby’s gender, Sims 4 makes it possible. In this guide, you’ll discover all the tried-and-true methods to speed up pregnancy, plus a few extra tips and tricks to help you control exactly how and when your new Sims arrive.

Your Sims Are Expecting—But Who Has Time to Wait?

If you’re the type of player who loves storytelling and capturing dramatic family moments—but dreads the slow crawl of Sim pregnancy—speeding things up can keep your game moving at a pace you enjoy. By default, pregnancy in The Sims 4 lasts three full Sim days (with each trimester spanning about a day), which can feel slow if you’re eager for your family to grow. Fortunately, the game’s built-in cheat system lets you manipulate time itself—well, at least where your Sims’ pregnancies are concerned.

How Pregnancy Progression Works in The Sims 4

Before jumping into cheats, it helps to know how pregnancy progresses by default:

  • Trimester One: Lasts 24 in-game hours. Your Sim will feel a bit queasy and get the telltale “eating for two” notification.
  • Trimester Two: Another day passes, and your Sim’s belly visibly grows.
  • Trimester Three: Final pregnancy day, complete with mood swings and discomfort.
  • Labor: After three days, your Sim automatically goes into labor and can give birth at home or the hospital.

With everything on “normal” lifespan, this sequence is set in stone—unless you intervene.

Speeding Up Pregnancy with Cheating

The most efficient, foolproof way to fast-forward pregnancy is by using cheat codes. If you’re comfortable with a little creative manipulation, this is the best route. Here’s how to do it step-by-step:

Step 1: Open the Cheat Console

  • PC: Hold Ctrl + Shift + C
  • Mac: Hold Command + Shift + C
  • PlayStation/Xbox: Hold down all four shoulder buttons

A slim white input bar appears at the top of your screen. Ready to work some magic?

Step 2: Enable Cheats

Type the following and hit Enter:

testingcheats true

If you get a confirmation message, you’re set. (If not, try testingcheats on instead—one of these will do the trick.)

Step 3: Use Pregnancy Advancement Cheats

Select the pregnant Sim as the active Sim, then pick the cheat to match your needs and paste it in:

  • Advance to First Trimester: sims.add_buff buff_pregnancy_trimester1
  • Advance to Second Trimester: sims.add_buff buff_pregnancy_trimester2
  • Advance to Third Trimester: sims.add_buff buff_pregnancy_trimester3
  • Start Labor: sims.add_buff buff_pregnancy_inlabor

You can jump to any stage instantly. Want to go all the way? Use the “inlabor” cheat and your Sim will be clutching their belly, ready for the delivery room.

What If Pregnancy Cheats Aren’t Working?

Cheats in The Sims 4 should work for every player, but sometimes they can act up. Here are a few troubleshooting steps:

  • Type cas.fulleditmode in the console and try cheats again.
  • Make sure the correct Sim is active (the one who’s pregnant!).
  • If you’ve got mods or expansion packs running, try disabling them temporarily. Rarely, certain mods/expansions conflict with pregnancy cheats.

Fun Modifiers: Twins, Triplets, or More

If you’re craving chaos or just want to fill up that nursery quickly, you can also determine how many babies your Sim will have. Here’s the format:

pregnancy.force_offspring_count [SimID] [number]

  • Find the Sim’s ID with sims.get_sim_id_by_name [First Name] [Last Name]
  • Replace [SimID] with the actual Sim ID, and [number] with how many babies (up to seven!) you want.

To skip the code-hunting, some players prefer using mods or pregnancy overhaul tools. For a deep dive, check out guides like The Sims 4 Pregnancy Complete Guide or experiment with community tweaks like the one featured on Sims Community.

Natural Ways to Nudge Pregnancy (Without Cheats)

Maybe you’re a purist and want some “organic” methods. While you can’t directly speed up pregnancy without cheats, there are a few ways to make the experience feel less tedious:

  • Shorten Game Lifespan: Go to Game Options > Gameplay and choose Short for lifespan. All Sims—including pregnancies—will age and progress quicker.
  • Use Fast-Forward: The “Ultra Speed” feature (three little triangles icon) makes game time zip along. It isn’t instant, but it can make those pregnancy days pass in a blur.

These tricks won’t let you jump from trimester to labor instantly, but if you want a slightly heightened sense of urgency (without breaking the immersion of your story), they help.

Other Pregnancy Controls—Gender, Parents, and More

While you’re playing with pregnancy, why stop at speed? Here are a few cool options for additional control:

  • Pick the Baby’s Gender:
    • Girl: Eat strawberries and listen to Pop music during pregnancy.
    • Boy: Eat carrots and listen to Alternative music.
  • Edit Pregnant Sims in CAS: With cas.fulleditmode enabled, you can even switch up traits or appearances.

Handy Tips for Making Sims Pregnancy Stress-Free

  • Remember, pregnancy cheats don’t harm your save file, but make sure you save before experimenting—just in case.
  • Mix and match cheats: Want twins and instant labor? Make it happen!
  • If you have the City Living or other expansion packs, use the on-lot traits “On Ley Line” to influence twins and triplets naturally.
  • If you get stuck, community guides like Carl’s Sims 4 Guide are packed with troubleshooting advice.

Feel free to get creative—after all, in The Sims 4, you’re the storyteller.

Frequently Asked Questions About Sims 4 Pregnancy Cheats

Why would I want to speed up pregnancy in The Sims 4?

Lots of players are interested in advancing their Sim families quickly—whether it’s for challenge runs, story progression, or just because waiting three Sim days feels like watching paint dry. Speeding up pregnancy helps keep things moving and lets you get back to the gameplay you enjoy most (whether that’s raising generations or causing chaos with surprise twins).

Can using pregnancy cheats mess up my save or game?

Pregnancy advancement cheats are safe for your save file and game stability. Still, if you’re experimenting with lots of cheats, it never hurts to make a backup save just in case.

Is there a way to have twins or triplets without cheats?

Absolutely! As mentioned earlier, try using lot traits like “On Ley Line” for a higher chance of multiples, or influence outcomes with features and foods found in the game. But if you want a guaranteed result, the cheat is your best bet.

Can you speed up pregnancy on console versions?

Yes! The cheat console (by pressing all four shoulder buttons) works on PlayStation and Xbox. The same pregnancy cheat codes work, as long as cheats are enabled.

Can I reverse pregnancy or delay labor with cheats?

Interestingly, you can also use the first or second trimester cheat to effectively “reset” the pregnancy to an earlier point. That way, if your story demands a dramatic delay, you have options.

Do mods offer better pregnancy control than cheats?

Some mods, like relationship or pregnancy overhauls, offer truly granular control—you can adjust time, stages, outcomes, and more. If you want a super-tailored experience (and don’t mind a little setup), exploring mods from trusted creators can expand your options. For inspiration, try resources like this overhaul mod guide.

Will the pregnancy speed-up cheats work with every expansion or game version?

For the most part, yes. However, unusual mod setups or rare conflicts with expansion packs sometimes cause hiccups. If a cheat isn’t working, try disabling custom mods/expansions, restart The Sims 4, and attempt the cheat again. Reliable guides like EA’s official pregnancy help page can keep you up to date.

Make Your Sims 4 Family Stories Unforgettable

There’s no right or wrong way to nudge, speed, or entirely control pregnancy in The Sims 4. Some players love the anticipation of three slow-moving Sim days, while others would rather race to the first diaper change—whatever your style, the game hands you the tools. Now you’re ready to play matchmaker, parent, and time wizard all in one. Happy Simming!
