Hello,
I've had the Sims 3 for Playstation 3 since its debut, and while I haven't played it every day or anything absurd, I still have yet to successfully conceive triplets with any Sim pairing. I'm beginning to get frustrated.
My latest attempt failed just this afternoon. The father is a World Reknowned Surgeon, the mother a Dynamic DNA Profiler. Both had their lifetime goals fulfilled early on in their Young Adult age, both have fertility treatments and are family oriented. During conception, the father had his needs at 100%, the mother had just been super satisfied and was under get lucky. The children's channel was on the television, and kids radio playing. Each day during the pregnancy, the mothers needs were kept at 100%, she read pregnancy and children's books, ate perfect quality food and went to the day spa, as well as having all of her wishes fulfilled as quickly as possible. Meanwhile, the father gave her medical advice daily.
What more can I possibly do?!
