In The Sims 4, your Sim can Try for a Baby, Have a Science Baby, or adopt. Romance is required for Try for Baby, but Have a Science Baby works solo or with a partner.
We’ll also cover adoption, gender tips, twins and triplets, and even Grim’s kids.
There are three ways to get pregnant or have a baby in The Sims 4: Try for a baby, have a Science Baby, or adopt.
How to try for a baby in The Sims 4
Have your Sims perform the Try for Baby action. Make sure to build up your relationship with another Sim, then click objects like the bed, shower, hot tub, or rocketship for the Try for Baby action to appear. Check out our WooHoo guide for all the locations your Sims can try for a baby.
How to have a Science Baby in The Sims 4
Use the power of science to have a baby alone or with another Sim by clicking on your Sim’s phone, opening the Home app, and choosing Have Science Baby.
How to adopt a baby in The Sims 4
Your Sim can adopt a baby over the phone, computer, or by adopting their partner’s baby.
Over the phone: Select your Sim’s phone and open the Home app. Choose Hire a Service then Call the Adoption Agency.
On the computer: select your Sim’s computer, then Household, and Adopt Sim.
Your partner’s baby: Adopt an infant, toddler, or child if your Sim is in a relationship with their parent. You’ll see the option to adopt under the Friendly action menu.
Elder Sims can Get Others Pregnant but can’t Become Pregnant. Teen Sims can’t get pregnant.
Yes, male Sims can get pregnant if you change the pregnancy options in Create a Sim under the gender selection dropdown menu. By default, only female Sims can get pregnant. Choose Become Pregnant, Get Others Pregnant, or Neither for any young adult or adult Sim. Read our sexuality, romance, and attraction guide for more help customizing gender and pregnancy options in The Sims 4.
How to tell if a Sim is pregnant
To know right away if your Sim is pregnant, select a toilet to take a pregnancy test for 15 Simoleons. You can also keep an eye on their Moodlets for signs of pregnancy and to see which trimester they’re in. Your Sim’s pregnancy will last about three days.
How to visit the hospital to give birth
Once your Sim goes into labor, you’ll have the option to select your Sim and choose to go to the hospital or have the baby at home. Although you can’t go to the hospital with them, they’ll return with their bundle of joy in no time.
Increase your Sim’s chance of having twins or triplets
None of these methods guarantee your Sim will get pregnant with twins or triplets; they just increase your chances.
What are the chances of your Sim having twins or triplets?
The odds of your Sim having twins or triplets are much lower than having a single birth.Your Sim has a:
10% chance of having twins
1% chance of having triplets.
To make twins or triplets more likely, use 3,000 satisfaction points to buy the Fertile trait in the rewards store. Your Sim earns satisfaction points by completing Whims.Buying this trait also increases the chances of the Try for Baby interaction working on the first try.
1
Open the Aspirations menu in the bottom right panel.
2
Select the Rewards Store.
3
Select the option with the baby bottle icon called Fertile.
If you own the The Sims 4 Outdoor Retreat Game Pack, you can make the Elixir of Fertility to increase the chance of twins or triplets. To create this herbal remedy, your Sim must be a Level 10 in the Herbalism skill. They’ll need these ingredients in their inventory, which can be found around Granite Falls.
1 Blackberry
1 Dust Spirit
2 False Morel
3 Morel Mushrooms
Select a stove, BBQ, or cauldron to brew up the potion.
If you own The Sims 4 Spa Day Game Pack, your Sim can get aFertility Massagethat increases their chances of having twins or triplets.
1
Select the Get a Massage option on the massage bed.
2
Choose Get a Fertility Massage. You can do this at the spa or on your home lot, but the Sim performing the massage must be a Level 9 in the Wellness Skill.
After the massage, your Sim will have a new moodlet, Fertility Boost, which lasts for around 12 in-game hours. Have your Sim Try for a Baby during this time to increase the chances of conceiving twins or triplets.
With the The Sims 4 City Living Expansion Pack comes a brand new lot trait, On Ley Line. Lot traits can be edited in Build Mode in the Venue Info menu found at the top left of the screen.
1
With theVenue Info menu open, click on the question mark icon to view the Traits Panel. This will bring up any traits your lot currently has so you can edit them.
2
Choose the On Ley Line lot trait. Using this trait means that twins and triplets are more likely when your Sim chooses the Try for Baby action.
How to influence a baby’s gender in The Sims 4
Trying some of the methods below while your Sim is pregnant can increase the chance of having a boy or a girl, but it’s not always guaranteed to work.
How to have a girl
Listen to the Pop Music genre.
Find a stereo.
Select Listen to.
Choose Pop.
Eat strawberries.
Find them growing in the wild (try searching Willow Creek).
Grow them yourself (you can buy seeds if you own Seasons).
If one of the parents of your baby is an Occult Sim like a Werewolf, Vampire, Spellcaster, Mermaid, or Alien, there’s a chance that your baby will be an Occult Sim. However, Ghost Sims can’t have children.These are the odds of your Sim baby being an Occult.
Relationship
Odds
Occult Sim + regular Sim
50/50 chance
Occult Sim + Occult Sim (different types)
Likely Sim baby will be either Occult type
Occult Sim + Occult Sim (same types)
Likely Sim baby will be the same Occult type, but can be a regular Sim baby
Regular Sim + Regular Sim
Not possible
There are other ways to have an Occult baby, plus ways to pass down special abilities and Traits:
Stargazing through the Telescope: There’s a chance your Sim could be abducted by Aliens and impregnated, resulting in an Alien baby. This can only happen to Young Adult or Adult Sims, who normally can’t become pregnant.
On a Dark Ley Line Lot Trait: this Lot Trait increases the chance that babies born on this Lot will be Vampires.
Spellcaster Bloodline Traits: For first-generation Spellcaster Sims, they’ll start off with no Bloodline Trait. Their children will have the Weak Bloodline Trait. If consecutive generations are Spellcaster Sims, this makes the bloodline stronger—it’ll go from a Strong Bloodline Trait to an Ancient Bloodline Trait. If consecutive generations aren’t Spellcasters, they’ll have the Bloodline Trait, but it’ll eventually disappear after a few generations.
Vampiric powers: the more powerful the Vampire parents, the more powerful a Sim will be when they begin their journey as a Vampire.
Werewolf Traits: some Werewolves can be born with no extra Werewolf Traits, but others can be born with:
Greater Wolf Blood Trait: they’ll gain additional experience when they unlock Werewolf powers.
Dormant Wolf Trait: They won’t become a Werewolf, but they can pass down the Werewolf bloodline to their children. Sims with this trait can Awaken the Werewolf Within, but it's optional. To do this, have them swim in Moonwood Mill’s Lake Lunvik at night during a full moon.
Having a baby with the Grim Reaper in The Sims 4
If you own The Sims 4 Life & Death Expansion Pack, the Try for Baby interaction is available with the Grim Reaper. For help initiating WooHoo with Grim, check out our WooHoo guide.If your Sim gets pregnant, the baby will be born with the Grimborn Trait. Sims with this Reward Trait will have a scythe birthmark behind their left ear and live longer. When these Sims have children, they’ll also have the Grim Descendant Trait, but they won’t have the birthmark or longer life span.Note: Young Adult or Adult Sims can get pregnant after WooHoo with Grim, regardless of pregnancy settings set in Create a Sim. If you also own The Sims 4 Growing Together Expansion Pack, when you have a baby with Grim, you’ll get the Had a Descendant of Grim! milestone.
