How you get a sim pregnant?

u can only get them pregnant on my sims 2. this is what u need to do...firs you need to buy a bed or a hot tub and put them in the bed make sure you put them in relax mode not sleeping mode or put them in the hot tub. then perhaps there will be a choice to try for baby and click on it. make sure ur the man when u go in the bed if ur the girl... the man will be pregnant ew.....!!!! anyway when the finish and u here a lullyby...BOOM your sim is pregnant. if u want one just leave it as it is if u want twins u need to eat a cheese cake. four eat 2 cheese cakes. HOPE THIS HELPS !!! ; )
