Is there a cheat to make your sim have a baby early?

Yes, in the sims 2 for PC open the cheat bar by clicking 'ctrl, shift, c' and the type in the cheat bar 'boolprop testingcheatsenabled true' Then shift click on a sim, and find 'spawn..' in the menu. Click on it. The click on 'the tombstone of life and death' immediatley a tombstones should appear by your sim. select the pregnant sim, click on the tombstone and then the option 'speed up pregnancy now' your sim should give birth within three sim hours, even if she has just become pregnant.
