Disable Aging

Instead of using a cheat code to toggle "aging on" and "aging off" like in The Sims 2, you can de-activate the age in "Game Options" under "Options". When you uncheck the box next to "Aging", your Sims will no longer become older. You can also slow aging down in this menu by setting the "Lifetime" bar. It can be set from 25 days to 960 days.

Magic Lama Time

Click the start button and press LB, LT, RB, AND RT all together and click the top bar that says yes and then go to build and buy and go to decor miscellaneous and it's in the first box and voila!
