Some non-human Sims can have a baby, which will typically have characteristics from both parent species. Zombies, SimBots, Servos, and Mummies cannot have children. [1] X Research source
100% chance: Vibromatic heart bed (High End Loft stuff pack) — baby will have Excitable trait 75%: Normal bed 75%: Sarcophagus (World Adventures expansion) 50%: Hot tub (various expansions) — baby will have either Hydrophobic or Party Animal trait 50%: Treehouse (various expansions) — baby traits depend on specific treehouse
It doesn’t matter whether you control the male or female Sim.
This option will not appear if your household lot already has 8 Sims living in it. There may be a small chance of pregnancy from the “Woohoo” option as well, but that’s an unreliable method. [3] X Research source
One way to know for certain if a female Sim is pregnant is if you click “Go Here” anywhere on the ground. If you do not have the options “Automatic,” ‘Run" or “Walk,” then you’re Sim is definitely pregnant. A short song right after the attempt is another sign of success. If this doesn’t happen, just try for a baby a second time. You can keep trying as many times as you like.
On day two, the mother will be visibly pregnant. She will also get a few days of maternity leave (paid time off work), starting today. On day three, meet the mother’s needs and address negative moodlets fast. If she is unhappy during this stage, you will not get to select the baby’s traits. At any point while pregnant, eating 3+ apples makes a boy much more likely. Eating 3+ watermelons makes a girl much more likely. [4] X Research source
The birth can happen very quickly, or last several game hours. Don’t let the noise or the panicking husband worry you — nothing bad can happen.
The Sim must be on his or her home lot to adopt.
The traits and appearance are always random, but you can improve future traits with a good upbringing.
Install the Seasons expansion. Collect Space Rocks if you can. (They appear mostly at random, but a Collection Helper speeds it up. ) Have a male Sim stargaze outside at night, using a telescope. Repeat each night until abducted. If the Sim has the Unexpected Weight Gain moodlet when he returns, he is pregnant. If not, try again.
