Get a Certain Child Gender on Sims 3

There is a sneaky way to aim for a particular gender when your Sims 3 character is pregnant. Oddly enough, it involves a trip to the grocery store. There is no way to guarantee the result 100% of the time, but this works in most cases.

Steps

Encouraging a Girl or Boy

  1. Start early. Pregnancy only lasts 72 Sim hours in The Sims 3. If you hear music while the Sims are trying to conceive a baby, they succeeded.[1] For the best chance of influencing the baby's gender, start right away, before the pregnancy bulge is visible.
  2. Consider turning off Story Progression. Although unconfirmed, there's a rumor that Story Progression tries to keep your town's gender ratio balanced.[2] In other words, if your town has more women than men, the game might force the next baby to be male. It's worth turning this off in the Game Options menu, just in case.
  3. Eat at least three apples for a boy. According to the Prima strategy guide, eating three apples during pregnancy makes it very likely that the baby will be a boy. This does not guarantee it completely, but it's the closest you can get without downloading a mod.
    • To be safe, some people recommend three apples each trimester (first, second, and third day of pregnancy).[1]
  4. Eat watermelons for a girl. This works the same way in the other direction. Have the pregnant Sim eat at least three watermelons to make the chance of a girl very likely.
    • Ever since an early patch (1.3), the fruit will only work when raw. Eating cooked foods that contain apple or watermelon has no effect on the baby's gender.[3]

Trying for Boy-Girl Twins

  1. Have-Twins-or-Triplets-in-the-Sims-3. All Sim pregnancies have a small chance of twins. You can't guarantee it, but taking these steps makes a multiple birth much more likely:[4]
    • Get the Fertility Treatment lifetime reward for one or both parents.
    • During pregnancy, have the parents read pregnancy books, watch KidZone TV, and listen to children's music. You may do all three at the same time.
    • If you have the Showtime expansion, wish for a large family with a genie, or drink a procreation elixir.[1]
  2. Ask a medical expert to identify the gender. Find a Sim that's at least level 5 in the Medical career track (Resident or higher).[5] Have the pregnant Sim have a friendly conversation with this doctor and ask to determine the gender of the baby. You will get a popup saying that you expect a boy or a girl. This prediction is always accurate — but only for one baby.
    • The pregnant Sim needs to be visibly pregnant before this option appears.
  3. Eat fruit to change the gender of the other baby. As described above, eat melons for a girl or apples for a boy. If you're lucky and end up with twins (or triplets), this increases the chance of getting the gender you want for the second child.
    • For example, if the doctor predicts a boy, eat melons to increase the odds of a girl. One baby will be guaranteed to be a boy, but if he has a twin, there's a high chance it will be a girl.

Tips

  • If you adopt a child, you get to choose the gender.
  • If your male Sim was Be-Abducted-by-Aliens-in-the-Sims-3, save the game just before the birth. If you don't get the gender you want, just reload the game and try again.[6] (This will not work for normal births).
