twinzr2cute does not work!!! just do force twins

One thing lots of simmers notice is if you give your pregnant sim desert at the right time, sometimes they'll have twins. I've tested this Cheat before, and it worked two out of four times, so it somewhat works, as long as you give them the desert at the right time (usually the first trimester)!

Well, my sims was on University. In University it's impossible to get pregnant. But I made my male sim alien pregnant and he gave birth to twin girls which I named Ashley and Maky Kate (lol). Too bad, it was too late for me to realized that once my sims left the University they can't bring the babies with them. Although I think it was the pizza that they were getting whenever they visit the campus that helped him get a twin! Not sure though.

open the cheatbox and type forcetwins
