How do you make children act like adults on sims 2?

you have to have 3 adults.type in that boolprop testingcheatsenabled true cheat.spawn a sim modder.make 2 of the adults children and quickly delete one of the them and go to the garbage, shift click it and click, reset age duration.if the social worker comes, press pause or p and shift click her and choose make selectable.then spawn rodneys death createrand make her die by flies.she might come again so, do that again. but shes going to lecture u so theres plenty of time, and the social worker wont clame the adult children.do this again to the other one and you will know when u did it right.
