Is it Possible to Save Scum for Triplets?

Topic. I've made both Sims fertile, have the Ley Line from City Living, but only one child was born. Are Twins/Triplets determined at conception, or can I keep resetting?

I am pretty sure babies are set at 'Try For baby' but I can't quite find the info I had on this to post the details. The Lot Trait 'Ley Line' isn't a guarantee for triplets but does help as long as your pregnant Sim in on the lot when they give birth. Going to the hospital or being on another lot negates the traits boosts.

Thank you for the information. I ended up getting pregnant with triplet aliens shortly after posting this without needing to reset, but that will be useful for the future. I apologize for bothering you with this.

No bother at all. Getting the exact result from a Sim pregnancy is always a RNG endeavor. The Ley Line lot trait actually doesn't seem to give that much of a huge % bonus but it may also treat the Hospital lot as a 'special lot' and so going to the hospital 'may' still be ok. tbh Carl has a hard time figuring exactly what the bonuses do with this lot trait and in-game testing from me swings all over the place! But to be safe, keep the pregnant sim on the lot that has the ley line trait to give birth and if you do want to save scum it would need to be just before your Sim trys for baby.
