The player will receive a notification when the pregnancy starts and when it progresses from one trimester to the next. The pregnant pawn will gain penalties to movement, manipulation, and hunger rate, increasing each trimester as seen in the chart below. Other than limitations due to movement, pregnant pawns have no restrictions on the activities they pursue. |

They vary in severity, direction, and duration, appearing as: "Pregnancy Mood (<duration>, <type>)" with the description ''This common side effect of pregnancy represents a rising and falling mood caused by unbalanced hormones.'' Accompanying this, the pawn will get a positive or negative moodlet labeled ''Pregnancy mood <type>''. Mood swings are short-lived, with the longest duration seen so far being 10 hours. |

− | + | Depending on the quality, the baby can be born healthy or sickly, or they may die during birth. At lower qualities, there is also a chance that the mother can die during childbirth. The quality needs to be >90% for the best possible outcomes. Since the probability of a bad outcome increases drastically below 20% birth quality, it's strongly recommended to provide at least the bare necessities, such as a bed indoors, as even a few percent above 0% in birth quality will contribute massively to the outcome. | |
