Sims 4 Cheats Twins
Like choosing a baby’s gender, there are two ways to influence if your pregnant Sim will have twins in The Sims 4 Cheats. The first and most efficient way is to use cheats. For this cheat code, you’ll need to get your Sim’s ID. You can do this by typing sims.get_sim_id_by_name (enter Sim's name here). When you enter this, you’ll get a long string of numbers that you’ll need to write down.
To make your pregnant Sim have twins (or triplets, quadruplets, quintuplets, or even more babies), bring up the cheat entry box and type in pregnancy.force_offspring_count (Sim ID here) (number of babies you want your Sim to have).
If you want to try for twins without cheats, you’ll have put in more work. You can get a Fertility massage if you know a Sim with the Wellness skill and have the Spa Day pack installed. Additionally, if your lot trait is “On Ley Line” you’ll have a higher chance of having twins. Again, though, the only way to make 100% sure you have twins is to cheat.
