[Update with Pics] My Sim just had natural identical triplets. I am going to die.
I did nothing, no fertility help, no lot traits. I wanted one kid for my ridiculously wealthy fashion photographer who married his self-absorbed, spoiled model. Three kids. I don't even. I pee...
I also had the same reaction for my first triplet kids, i was like "Nice, a boy" - "Oh, he is having a twin" - "What the? Another one?" Good thing my sims still live with his parents to help him took care his triplets
