In gaming, pregnant characters are often made immortal and in the Sims 4, it goes so far as to have them defy aging as well. While it would be absolutely lovely if every pregnant person was protected from father time and the grim reaper, that’s now how it works in the real world, unfortunately. With this mod, your pregnant sims will continue to age up like they normally would and they are also susceptible to the various deaths possible for non-pregnant sims. There are also optional add-ons for toddler & children death too, if you really want to go gritty.
