@sumpsychochic. You can get twins of mixed gender but you need to know a sim who is fairly high up in the medical field. I am not taking credit for discovering this myself, by the way, but I have tested it and it works. If you are pretty sure your sim will have twins because she has the fertility treatment, get your doctor friend to 'examine' your sim. The doctor will tell your sim if she is having a girl or boy and then you must make your sim either eat three servings of watermelon or apples - depending on what you want.
I love this sim. She is so pretty in game and very popular with all the guys. Everyone has three bolts for her. I called her Halle Berry because she reminds me of her.
Yay! I finally got her and I did it in Russian too Using the translated sites didn't work for me but I picked up where to look for the links from trying them.
She is really lovely and worth the extra work to get her. You did a great job.
Thank you. She is lovely and is now in my game. I have made her knowledge/family. I called her Maggie - only because I knew a Nualah and she wasn't nearly as beautiful as your sim
