In the official version of the game, only Young Adults (who are implied to be in their early 20s) and Adults can get pregnant. Sims have seven stages of life, from Babies to the Elderly. Teenage pregnancies aren’t possible in The Sims 4 by default. Their descriptions sometimes specify how many children they’re expecting, and many of them are pregnant with twins. More often than not, however, these Sims are alone. Some of them come packaged with their mothers, who are often also pregnant, and some have the father of the baby in the household as well. There are teens pregnant with quadruplets and pregnant teenagers that also have dogs or cats. If you log into the game and check the box that allows Sims with custom content to show up in search, and then search “pregnant” in the gallery, the abundance of pregnant teenage Sims is startling.
