How to Have Twins on Sims 4

The Sims 4 is an engaging life simulation video game that allows players to create and control virtual lives.

It’s no secret that players enjoy expanding their Sim families, and what’s more exciting than welcoming a set of twins into your virtual world?

If you’ve ever wondered about the intricacies of how to have twins on Sims 4, you’re in the right place.

In this detailed guide, we will delve deep into the mechanics, strategies, and hidden secrets that will increase your chances of having twin Sim babies.

How to Have Twins on Sims 4: The Basics

Having twins in The Sims 4 is not entirely under your control, but there are ways to increase the odds. From simple gameplay mechanics to cheats, we’ll cover it all.

  • Fertility Trait: In the Sims 4, adults can choose the ‘Fertility’ reward trait which increases the likelihood of having twins or triplets. This trait can be purchased using satisfaction points, which are earned by fulfilling your Sim’s desires and objectives.
  • Fertility Massage: If you have the Spa Day game pack, pregnant Sims can get a Fertility Massage at the Spa. This increases their chances of having multiples.
  • Ley Line Lot Trait: This lot trait, available with the City Living expansion pack, can be added to any lot. It increases the chances of your Sims having twins or triplets.

Understanding the Role of Genetics

The Sims 4, like real life, utilizes genetic mechanics. This means that if twins or triplets run in your Sim’s family tree, their chances of having multiples could be higher.

  • Dive Into Your Sim’s Genealogy: Understanding your Sim’s lineage can give insights. If their parents or grandparents were twins, there might be a higher likelihood of them having twins too.
  • Look for Patterns: If you’ve been playing a particular Sim family for generations and notice a pattern of multiples, it could be worth considering when planning for a baby.

Increasing Your Odds With Gameplay and Cheats

For those who are eager to skip the odds and guarantee a set of twins, there’s a cheat for that!

  1. Enable Cheats: Press CTRL + SHIFT + C on your PC or Command + SHIFT + C on a Mac to bring up the game’s console. Type “testingcheats true” to enable cheats.
  2. Input the Pregnancy Cheat: Once cheats are enabled, shift-click on the pregnant Sim while they are selected. Navigate to ‘Pregnancy’ and then ‘Pregnancy Phase’. Here, you can choose the ‘Twins’ option.

Factors That Don’t Affect Twin Births

It’s essential to dispel myths around factors believed to influence twin births in The Sims 4:

  • Food: While some believe eating certain foods in the game increases the chances, there’s no factual basis or evidence to support this in the game’s coding.
  • Watch Kids Network: A popular rumor is that watching the ‘Kids Network’ on television increases twin births. However, this has also been debunked.

Personal Experiences With Twins in The Sims 4

First-hand experiences provide valuable insights. I remember the joy of unexpectedly having my first set of twins in the game.

It made managing the household more challenging, but also more rewarding. One key takeaway from my gameplay hours is the importance of preparation.

Twins require more attention, more space, and can be a handful. It’s always beneficial to have a nursery ready and perhaps even consider hiring a nanny for the initial days.


Having twins in The Sims 4 can be an exhilarating experience. While there’s no surefire method to guarantee twins without cheats, understanding the game’s mechanics and enhancing your chances can lead to delightful twin surprises.

Whether you’re using the Fertility Trait, opting for a Fertility Massage, or diving into cheats, the joy of having twins is just a few clicks away. So, are you ready to take on the delightful challenge of twins in The Sims 4?
