There are three ways to get pregnant or have a baby in The Sims 4.

• 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.
• 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.
• Adopt a baby over the phone or computer, or adopt your partner’s baby.
  • Over the phone: Click your Sim’s phone and open the Home app. Click Hire a Service, then Call the Adoption Agency.
  • On the computer: click your Sim’s computer, then Household, and Adopt Sim.
  • Your partner’s baby: You can also 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.

Note: if you own The Sims 4 Life and Death Expansion Pack, Child Sims (dependants) can be left to another Household in a Will. For more information on Wills, check out our guide.

Which Sims can get pregnant?

Although by default only female Sims can get pregnant, you can change your Sim’s pregnancy options under the gender selection dropdown menu in Create A Sim so that male Sims can get pregnant too.

You can choose Become Pregnant, Get Others Pregnant, or Neither for any young adult or adult Sim. Elder Sims can Get Others Pregnant but can’t Become Pregnant.

How do I know if my Sim is pregnant?

To know right away if your Sim is pregnant, click on 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 do I visit the hospital to give birth?

Once your Sim goes into labor, you’ll have the option to click on 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 your bundle of joy in no time.

If you own The Sims 4 Get to Work Expansion Pack, you can visit the hospital when your Sim gives birth.

Remember that none of these methods guarantee your Sim will get pregnant with twins or triplets; they just increase your chances!

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.

To have a girl:

• Listen to the Pop Music genre:
  
  • find a stereo
  • click Listen to
  • choose Pop.
• Eat strawberries:
  • find them growing in the wild (try searching Willow Creek)
  • grow them yourself (you can purchase seeds if you own Seasons)
  • buy them at a market stall if you own Cottage Living or City Living.

To have a boy:

• Listen to the Alternative Music genre:
  
  • find a stereo
  • click Listen to
  • choose Alternative.
• Eat carrots:
  
  • find them growing in the wild (try searching around Oasis Springs)
  • grow them yourself (you can purchase seeds if you own Seasons)
  • if you have Cottage Living or City Living, buy them at a market stall.

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:

There are other ways to have an Occult baby, as well as 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, when you have a baby with Grim, you’ll get the Had a Descendant of Grim! milestone.
