@Murry2211 I think you would need a mod for that. I suppose you could save as soon as you go into labor, and if you find you have twins you could exit without saving, then re-enter and do the birth again and use the twin names.
@Murry2211 There was another cheat called pregnancy.force_offspring_count that you might still come across in various game guides when researching this topic (i.e. multiple babies). It used to allow a player to force a specific number of babies for a pregnant Sim. This cheat was disabled by EA about a year or so back because it had the potential of REALLY messing up your game save. If you see that cheat still listed anywhere just ignore it.
@Murry2211, in addition to what @SheriGR and @RandomBuzziness have suggested, you can also try Reward Traits and Lot Traits to increase your chances of having more than one baby. The Lot Trait is free and is called "On a Ley Line" and increases the chance of having a baby, and supposedly increases the chance of multiples.😇
But for multiples it would probably best to get a Reward Trait from the Aspiration Rewards Store on your Sim's Aspiration Panel. There are a lot to choose from, the one that increases the chance of having twins or even triplets is the "Fertile" reward trait.🙂 To be extra sure you can have both the mother and the father get this trait.
However, there is a Bug Report on the Fertility reward trait. 😞 There isn't a lot of information on if this is an actual bug or not, as only a few people have reported it.🤔 Here is the thread on it https://answers.ea.com/t5/Bug-Reports/NEEDS-INPUT-Fertile-Trait-not-working/td-p/8632454
But it can't hurt to give it a try! 😉
