Sims 4 A Child Sim Can Live Alone But Can They Survive?

Gracie has been abandoned and is going to try to survive on her own.
Will she be able to live on granola, cereal and yoghurt or is she going to get so bored that she will have to resort to eating verdant mushrooms.
And a bear suit is a must.

How did you get a child sim alone without a game over? I thought that was automatic.

Hi, I actually used a cheat. If you shift click on the adult sim you get an option to remove them from the family. They disappear but do occasionally turn up to visit.
