While most of the larger pregnancy overhaul-type mods will give you the ability to change the duration of a pregnancy, for players who don’t want to deal with too many options or changes to their game, a mod like this is useful. All it does it change the duration of the pregnancy, no more and no less. Options range from 1 day to a whopping 147 days for those playing with aging off or who just really, really like their sims being pregnant.
