"The Sims 4" Walkthrough: Guide to Pregnancy and Babies

All sims have to start somewhere, and for most next-generation sims, that means beginning as babies. Yes, your sims can give birth to children if they’re so inclined and can thereafter raise and care for those children. Such has always been a part of The Sims, and though The Sims 4 removes toddlers from the equation, all the joys of raising babies into children remain in the game.

Creating a child is easy, as you can do it in Create a Sim. You can even connect that child with pre-existing parents to create a family from the get-go. Creating a baby, though, ah, that’s a little trickier. Let’s have a look at how it’s done.

The first step to creating a child is pretty obvious: impregnating one of your female sims. In order to do this, you must first infatuate a male sim with a female sim. They don’t need to be married, but their affection needs to be sufficiently high that the two sims can WooHoo. This is probably the most difficult part of the process. Here are some tips for making it happen:

  • Choose sims with similar interests and attitudes to expedite the process. Sims that dislike each other can build a romantic relationship, but it will take longer - and it’s possible that they’ll rip down all your work a few times when they start to interact free of your meddling. Choose the Get to Know conversation option to puzzle out the stranger sim’s Traits to make sure you aren’t wasting your time.
  • Choose sims you know your sim can interact with on a regular basis. It takes at least a few hours of in-game time to build up a relationship, and your sims need to be available at the same times of the day to converse. Ideally, you want your sim to be in a good mood during these interactions, as a sour mood can turn a relationship nasty.
  • Try to make your sim Flirty before conversations. Flirty sims have an easier time building up a romantic relationship. You can make a sim Flirty through dialogue options alone, but it’s faster to make them have a Steamy Shower before the conversation. (You can also order the sim to purchase and use a Flirty Potion from the Rewards Store, but these things are expensive.) That said, don’t jump right to Flirty interactions with a stranger - the two sims should at least be friends before you turn on the romance.

Once you have two sims that are willing to WooHoo, look for the Try for Baby option on the conversation wheel. Select this with a double bed available, and sparks will fly.

Getting Pregnant

As in real life, Try for Baby is not always an automatic success. Your sims may have to Try for Baby several times before you’re successful. (The Fertile Reward Trait can help if things just aren’t clicking for your sim.) The only way to check if your female sim is pregnant or not is to select them as your active sim and click on a nearby toilet, which will display the Take Pregnancy Test ($15) option. Do this, and, assuming the two sims were successful, the female sim will receive the Eating for Two! bonus (as well as abruptly gain weight). If nothing happens, you’ll just have to try again.

The Pregnancy

The rest of this process is fairly straightforward. Your female sim will now have a pronounced baby bump, and she’ll proceed into the second and third trimesters of her pregnancy over the next two days. Not much changes in the second trimester, though in the third, your sim will likely become uncomfortable often from hefting around her new load. Avoid physical activities while in the third trimester. During these days, your sim can show off her baby to other sims, and to the father in particular; depending on how much these sims like children, reactions will vary. (And no, you don’t have to Share Big News with the father. He’ll figure it out on his own. You’ll usually get a mood bonus by doing so, however.)

During the sim’s third trimester, she will, at some point, hit Gone Into Labour status. Once this happens, the sim will become extremely uncomfortable until she gives birth. Put a bassinet in your home, and you’ll have the option to Give Birth or Give Birth at Hospital; either way, you have a baby. If your sim has twins or triplets, you’ll magically receive additional bassinets. (I have been told that the sim will eventually have the baby on her own if you don’t do anything to trigger the birth. In this case, you seem to get a free bassinet.)

Raising Babies

Babies in The Sims 4 are treated as highly interactive items. When not being carried by an older sim, babies remain in their bassinets and have no independent actions. They will, however, react to a lack of attention from older sims, and their moods fluctuate often. There’s a range of actions for appeasing babies; mothers receive a few more options beyond those afforded to other sims. Choosing these interactions, particularly those that feed the baby, usually appeases your tyke.

Tired of your baby and want it gone? Babies will age on their own, but you have an additional option from birth: Age Up. Aging Up a baby will instantly transform it into a child, regardless of how long the infant has been alive, and you’ll receive a new member of the household, complete with one of four child-unique Aspirations and one starting Trait. From this point on, the child occupies one of the eight slots in your household, and you can control them like any other sim. Ah, the cycle of life.

It worked but she ended up with triplets. I don't know how. They were all girls.

Really? I've had auto growth immediately every time my sims have had a baby. Could be a bug. Might also be an effect of turning off aging, if you've done that for your sims.

Dimensioni Creative on September 16, 2014:

How many days I must wait for the automatic growth? Cause my baby after 8 days is still in the cradle...

Matt Bird (author) from Canada on September 15, 2014:

I really don't know what to say on the hospital thing. I KNOW I've had the option to send a sim to a hospital, and it sounds like others have too. I'll have to take a screenshot. (And no, there's no physical hospital. As far as I can tell there's absolutely no difference whatsoever between having the baby at home and having it in a hospital.)

As for the Try for Baby / normal Woo Hoo thing, I believe your sims could get pregnant just by Woo Hooing in previous games - the chances were just much lower than if you were deliberately trying for a baby. Don't honestly know if that's the case here.

Clare on September 15, 2014:

Can sims get pregnant without clicking the "try for baby" action?

My fella is sure he never clicked that option and shes pregnant!

holly on September 15, 2014:

there is no hospital in the sims 4 :)

Valoofa on September 14, 2014:

Should I get sims 4??

Matt Bird (author) from Canada on September 09, 2014:

I've held off on replying to this mainly because I'm not sure if that's the only prerequisite. My fiancée was playing a few days ago and she didn't get the option for birth in a hospital either. I'll have to tinker before I can give a definitive answer. Normally, though, yeah, it's just clicking and choosing.

TeCh on September 08, 2014:

Just click on the pregnant Sim that's going into labor and you'll get an option to give birth in a hospital.

Chiara on September 07, 2014:

Sorry but I don't know how call the hospital!
