Sims that are already confirmed pregnant can use this without the force twins/triplets stuff. It's very simple. SAVE, then type into the console: Sims.Add_Buff Buff_Pregnancy_Inlabor - now the Sim goes into labor immediately and has the babies. We can save again in a new slot to divert it from our original branch in case something goes wrong.
