Game guide:Making a child or younger live alone

How to do
(Note:This only works on The Sims 3.)

There are two ways of making a child or younger live alone. The first way consists of killing off the parents, then play the child again straight after it gets you off the household. Notice the babysitter will stay no matter what. The second way consists of playing another household and make the parent of the desired household with the child the player wants to live alone. Make the parents join the household through "testingcheatsenabled true", then go on to the newly alone child.

Cautions
When aging from Toddler to Child, unless you didn't do this before the toddler was trained toddler skills, you can't choose a trait. This is due to the babysitter not being programmed to teach them.

If you go into Edit Town, you can't play the alone child again.

If a child throws a party with a toddler in the household the babysitter will leave. However, this can make the child totally alone.

Try This
Make the child and then make a random adult (or use a pre-made family).

Pull up the cheat box (Ctrl, Shift, C) and type in "TestingCheatsEnabled true"

Shift click on the adult and go "object" and then "delete"

Enjoy
