Make Kids Grow Up in The Sims

You can't make your kids grow up naturally on the sims, but if you buy certain versions of the games, there is a way. Read on!

Steps

Purchase the Sims Makin' Magic expansion pack.
Learn the magic spells and charms.
Buy a bookshelf and read the spell book and cook book to find out what you need for specific magic.
Gather the ingredients for the spell, The Age of Instant. (two dragon scales and one toadstool-you must be an adult to get and use these items-children can not).
Get the child to take it out, and put in the kid spell maker (this makes a charm). Simply cast the spell and voila, you're done!

Open the cheat window (ctrl+shift+c) and then type in "boolprop testingcheatsenabled true" and press enter or return.
Go to the person you want to age.
Left click the person at the same time as pressing the shift button.
Continue holding down shift and the left mouse button until you find SPAWN.
Press "SPAWN".
Continue clicking "SPAWN" until you get to "SIM MODDER".
Click on "SIM MODDER" and a baby doll will appear.
Click on the baby and continue clicking until you see "SET AGE"
Click on "SET AGE"
Choose from Toddler, Child, Teenager, Adult or Elder.
Once you choose, your character is now that age!

For the Sims cheat you need a magic wand (this can be bought from the Magic Man).
Doesn't work out for Sims Free Play.

Kids will still be living with adults until they get married or move in with someone.
