Hi guys, today I am going to show you how to add a sim to your family in Sims 3. The first thing to do is go to the menu (that dot icon at the bottom left of the screen) and click town edit. Then you will see your sims family and others that the game made. Then you click create a sim. After you're done making your sim and push done you might get confused because it says that the sim you just made is in a different household. Don't worry, you click on the sim then place a copy in the house that your other sim is in. They then move in. So that's it. I hope you enjoyed this post. If you want more info on sims be sure to leave a comment. Thanks.😉
