Want to double the joy (and the chaos) in your Sims’ household? Having twins in The Sims 3 is entirely possible, and there are several ways to increase your chances — both naturally and with a little help from the game’s mechanics. Here’s your ultimate guide on how to have twins in The Sims 3.
How to Increase Chances of Twins
- Fertility Treatment Lifetime Reward
The easiest and most reliable method is purchasing the Fertility Treatment Lifetime Reward. You can find it in the Lifetime Happiness panel for 10,000 points. Both parents having the reward increases the chances even more. - Listen to Kids Music or Watch Kids TV
During pregnancy, have your Sim listen to kids music on a stereo and/or watch the Kids Zone channel on TV frequently. This significantly raises the likelihood of having twins or even triplets. - Eat Specific Foods (Limited Effect)
While food types mainly influence the baby’s gender (e.g., apples for boys, watermelons for girls), there’s no proven meal that boosts twin chances. Stick with music and TV for results. - Use Cheats or Mods
If you’re open to it, you can use mods like NRaas MasterController to force twin or triplet pregnancies. You can also use the “testingcheatsenabled true” cheat and shift-click a pregnant Sim to manually trigger twins.
Managing Twins in Sims 3
- Prepare the House: Get two cribs, high chairs, and plenty of baby supplies ready in advance.
- Hire Help: A babysitter or butler can be a lifesaver when caring for multiple infants.
- Alternate Sleep Schedules: To avoid complete exhaustion, take turns with each parent caring for the twins.
