You’re playing The Sims 4. Your teen Sims just had their first "Mess Around" session in a shower or a bush. You wait for the morning sickness. You wait for the little confetti pop or the nausea moodlet. But it never comes. Honestly, if you're looking for a teen pregnancy feature in the base game, you’re going to be waiting forever. EA just doesn't put that kind of stuff in their T-rated titles. It’s a legal thing, mostly.
The truth about pregnant teens Sims 4 gameplay is that it exists almost entirely in the world of mods. People get really confused by this because they see screenshots or YouTube "Let's Plays" where a teen has a baby bump. They think it's a hidden cheat. It isn't. Without external software, your teenagers are effectively biologically incapable of conceiving.
Let's get into how this actually works.
The Technical Reason Why Your Teens Aren't Conceived
In the vanilla game, "Try for Baby" is an interaction strictly reserved for Young Adults, Adults, and Elders. Teens only get "Mess Around." It’s basically a PG-13 version of WooHoo that builds the romance bar but has a 0% chance of resulting in a pregnancy. Even if you use the sims.add_buff buff_pregnancy_trimester1 cheat on a teen, the game often glitches out because the teen character model isn't rigged for the pregnancy belly animation by default.

Many players think the High School Years expansion pack changed this. It didn't. It added prom, graduation, and "sneaking out," but it kept the reproductive mechanics the same. If you want pregnant teens Sims 4 stories, you have to look toward creators like Deaderpool or Lumpinou.
How Mods Change the Game (The MCCC Method)
If you've been in the community for more than five minutes, you've heard of MC Command Center (MCCC). It's the Swiss Army knife of Sims mods. To enable teen pregnancy here, you actually need two parts: the main MCCC mod and the MC WooHoo module.
Most people mess this up by only downloading the base file.
- Open the MCCC menu via an in-game computer.
- Navigate to MC WooHoo.
- Find "WooHoo Settings" and then "Allow Teens."
- Go back to MC Pregnancy and adjust the "Pregnancy Age" settings to include Teens.
Once those are toggled, the "Try for Baby" interaction suddenly appears for your younger Sims. It’s that simple, but keep in mind that every time the game updates, MCCC usually breaks. You’ll be staring at a "Script Call Failed" error if you don't keep your files current.

Realism with the Relationship and Pregnancy Overhaul
If MCCC is the technical fix, Lumpinou’s Relationship and Pregnancy Overhaul (RPO) is the storytelling fix. This mod is massive. We're talking about 15+ modules that cover everything from paternity tests to "the talk" with parents.
What makes RPO special for pregnant teens Sims 4 gameplay is the reaction system. In the base game, if a Sim gets pregnant, everyone is just... happy? They clap. They cheer. In RPO, you can have a teen Sim "confess" the pregnancy to their parents. The parents might be supportive, or they might be absolutely furious. You can even be kicked out of the house. That’s the kind of drama that makes the "Teen Mom" challenge actually interesting.
The "No-Mod" Workaround (Kinda)
Can you do this without mods? Technically, yes, but it’s a bit of a cheat-y workaround that feels a little hollow. You can use the cas.fulleditmode cheat to age your teen up to a Young Adult, get them pregnant, and then immediately age them back down to a teen.
The game will recognize the pregnancy state even after they’ve shrunk back down to their high school self. However, their body might look a little weird. Since the teen and adult heights are now the same in The Sims 4 (unlike in The Sims 2), the belly usually scales correctly, but you might see some clipping with their clothes.
Why EA Won't Ever Make This Official
There is a lot of debate on the forums about why this isn't a feature. Some players want the realism. They want to play through the struggle of a Sim trying to finish high school while raising an infant. Others think it’s too dark for a game about "playing with life."
EA's stance is pretty clear: they want to keep the "Teen" life stage as a romanticized version of high school. Including teen pregnancy would likely push the game’s ESRB rating from "Teen" to "Mature" in many regions. That would hurt sales. It’s also a PR nightmare they’d rather avoid. This is why the community has taken the reins.
Actionable Tips for Your Save File
If you’re planning to run a pregnant teens Sims 4 storyline, don't just download a mod and hope for the best. You need to prep your game or it'll break.
- Check your clothing CC: Many custom content creators don't enable their clothes for "Pregnancy." If your teen Sim is wearing CC and gets a bump, her torso might just disappear. Look for "Pregnancy Tagged" CC.
- Manage School: If your teen is pregnant, they still have to go to school in the vanilla game. Use MCCC to allow "Quit School" for teens if you want them to stay home with the baby.
- The Science Baby Loophole: Interestingly, the "Science Baby" feature added recently allows for some weird family trees, but it still honors the age gate.
Start by installing MC Command Center if you want a quick toggle, or Lumpinou's RPO if you want the deep, emotional baggage. Always clear your localthumbcache.package file after installing these to make sure the new interactions show up properly in the pie menu.

Next Steps for Your Gameplay
To get started with this storyline, your first task is to verify your game version against the current mod version. Download the MC Command Center base and MC WooHoo modules from Deaderpool's official site. Once installed, use the in-game computer to enable the "Teen" age group in the Pregnancy and WooHoo settings. This will unlock the "Try for Baby" interaction immediately.
