Pregnancy

Overview

Pregnancy in inZOI lasts 3 in-game days and progresses through three visible stages. It requires a specific action separate from intimacy, is not guaranteed on the first attempt, and produces a newborn that ages into a Toddler after 1 day. The system has received significant updates since launch. Earlier versions required marriage, but v0.2.0 (June 2025) removed that restriction and added two alternative methods for having children: adoption and Medical Birth. The v0.7.0 anniversary update (March 2026) added pregnancy due date tracking on the in-game calendar, baby customization in the Edit Appearance menu, infant bathing, and a suite of new parent-child interactions.

There are now three ways to add a child to a household: biological pregnancy, adoption, and Medical Birth. Only female Zois can become pregnant in the current Early Access build.

Requirements

For a biological pregnancy attempt to be possible, several conditions must be met:

• The couple must have a strong romantic relationship. Casual acquaintances cannot attempt pregnancy.

• The household must have fewer than 8 members. At maximum family capacity, pregnancies automatically fail.

• Only female Zois can become pregnant.

• Both Zois must be at the Young Adult life stage or older (Young Adults and above).

• Marriage is not required. This restriction was removed in v0.2.0 (June 2025). Unmarried couples with a strong enough romantic bond can now have children.

Initiating Pregnancy

Pregnancy is initiated through a dedicated action, not through the general intimacy interaction. To start:

1. Click on the partner Zoi.

2. Select More, then navigate to the Romance category.

3. Choose "Suggest Having a Baby."

4. The couple typically moves to a bedroom.

Success is not guaranteed. The game rolls a probability check, and failure means the Zoi simply did not conceive. Multiple attempts may be necessary. There is no visible probability number or fertility stat.

Confirming Pregnancy

When conception succeeds, a red exclamation mark appears on the female Zoi's portrait icon. Click it to prompt the Zoi to take a pregnancy test. She will walk to a toilet, use it, and a notification will confirm or deny the pregnancy. Until the test is taken, pregnancy is not officially confirmed in the game's records.

Pregnancy Due Date Tracking

As of v0.7.0 (March 2026), confirmed pregnancies are tracked on the in-game calendar. The new 28-day calendar displays due dates for pregnant Zois alongside seasonal holidays, birthdays, and other important events. This allows players to plan ahead for the birth and arrange schedules around the expected delivery date. The due date appears automatically once the pregnancy test is confirmed.

Pregnancy Stages

The 3-day pregnancy divides into three distinct stages, each lasting approximately one in-game day (roughly 48 real-world minutes at the current default speed since v0.4.0):

Throughout all three stages, appearance editing is disabled. The player cannot change the Zoi's clothing, hair, or body through the character creation editor until after the birth.

Special Pregnancy Interactions

Giving Birth

After 3 in-game days, a Give Birth prompt appears as a red exclamation mark over the Zoi's head. Clicking it causes the Zoi to automatically travel to the hospital. A loading screen plays, followed by a brief cutscene showing the Zoi in a hospital bed holding the newborn. The player is then prompted to name the baby and assign a gender.

If the Give Birth prompt is missed or dismissed, the birth still happens automatically after approximately 5 in-game hours. The baby will appear in the household crib with a random first name and the father's last name. The name can be changed later through the Zoi's profile.

Baby gender is random and cannot be influenced in the current build. Players have requested gender selection or influence mechanics on the official forums, but these remain wishlist items.

The Newborn

The newborn appears in a crib in the household. A trait is randomly assigned at birth. Physical features like hair color, eye color, and facial structure are inherited from both parents through a genetics system that blends traits from both parents. The v0.2.5 hotfix specifically fixed an issue where "facial features of newborn Zois generated via genetics appeared unnatural."

Baby Customization (v0.7.0)

The v0.7.0 anniversary update introduced the ability to customize baby Zois in the Edit Appearance menu. Players can now open Create-a-Zoi for their babies to change outfits and use the photo studio. Six new baby outfits were added in this update, providing a variety of clothing options for newborns and infants. Before this update, baby Zois were locked into a default appearance with no way to change their clothing.

Tooth Development (v0.7.0)

Starting with v0.7.0, newborn Zois are born without teeth. This visual detail was added for realism, as real newborns do not have visible teeth. As the baby grows and ages, teeth gradually appear. This cosmetic change does not affect gameplay or feeding mechanics, but it adds a layer of visual authenticity to the early life stages.

Newborn Care (Day 1)

The Newborn life stage lasts exactly 1 in-game day, after which the baby automatically ages into a Toddler. During the Newborn stage, interactions are very limited:

• Check Their Temperature (the only Parenting menu option)

• Talk to the baby and show affection (builds relationship)

• Socialize and observe the baby

Newborns cannot be fed (feeding only unlocks at the Toddler stage), cannot be held or carried around, and are confined to their crib at all times.

New Baby Interactions (v0.7.0)

The v0.7.0 update significantly expanded baby-related interactions. New interactions were added between Zois and babies, between babies and objects, and between babies and their environment. Key additions include:

Baby Needs and Urges (v0.7.0)

Baby Zois have had their needs system rebalanced in v0.7.0. The update adjusted need decay rates to create smoother interactions and less frantic care routines. New urges have been added specifically for newborn, toddler, and children Zois, giving them more autonomous behaviors. Some of these new urges lead to parent-child conflicts, adding depth to family dynamics. Additionally, family members will now die less frequently from low needs, reducing the risk of unexpected deaths during busy household management.

Toddler Care (Days 2 to 3)

Once the baby ages into a Toddler, the range of available interactions expands significantly:

If a toddler's needs (particularly hunger) are severely neglected, the Child Protection Agency will remove the child from the household rather than the child dying.

Babysitter Service

Parents can hire a babysitter through the Pocketmarket phone app. Two service tiers are available:

Babysitters handle feeding and diaper changes. The service is only available for households with toddlers, not newborns. Note that v0.7.0 fixed an issue where babysitters would persist abnormally after their service period ended.

Birthday System and Aging Up

The v0.7.0 update introduced a birthday system tied to the new 28-day calendar. Zois now advance to the next life stage on their birthdays rather than after a fixed number of days. There are two ways for a Zoi to age up:

• Birthday party: Throw a birthday party and have the Zoi blow out candles on a cake. Birthday parties can include gift-giving and pinata smashing. Note that birthday parties can only be thrown for Zois who are older than babies.

• Solo celebration: If no party is held, the Zoi will spend their birthday alone and age up without a candle-blowing animation.

Birthdays are tracked on the calendar automatically, making it easy to plan celebrations ahead of time. The system ties into the new memory system, which records significant life events from a Zoi's first steps to having their own child.

Life Stage Durations

For reference, here are the durations of each life stage. One in-game day equals roughly 48 real-world minutes at the current default speed (changed from 96 minutes in v0.4.0).

The ageUp cheat can force instant aging. Day length can be adjusted in settings, which affects real-world time for each stage. With the v0.7.0 birthday system, aging now occurs on the Zoi's birthday rather than strictly after the listed number of days.

Twins

Twins are not currently available in the game. Early Access promotional materials showed families with two babies, hinting at twins, but no player has confirmed getting twins in regular gameplay despite extensive testing. No cheat code exists for forcing multiple births.

The official 2026 roadmap explicitly lists "Implement multiple pregnancies such as twins and triplets" as a planned feature under the "Fundamentals First" initiative, but no specific release date has been given.

Adoption

Adoption was added in v0.2.0 (June 2025) and provides an alternative path to expanding a family without biological pregnancy. This allows same-sex couples, single Zois, and anyone meeting the requirements to add children.

To adopt:

1. Go to a computer or laptop in your home.

2. Select "Adopt a Child" under General Actions.

3. Choose the child's age: Newborn, Toddler, or Child.

4. Confirm the adoption.

Medical Birth

Medical Birth ("Create a Child with Medical Help") was also added in v0.2.0 and provides a third method for having children. It costs 1,000 Meow and works for all gender combinations, including same-sex couples.

To use Medical Birth:

1. Go to a computer or laptop.

2. Select "Create a Child with Medical Help" under General Actions.

3. Choose to go solo (child inherits only your traits) or with a partner (child inherits both parents' traits).

4. If choosing a partner, the other Zoi must give consent.

Known bug: For unmarried couples (especially same-sex), the baby may only recognize the Zoi who initiated the Medical Birth as family. The partner is not recognized as a parent. This has been reported on the official forums.

Patch History

Planned Features (2026 Roadmap)

The official 2026 roadmap includes several pregnancy and family features still in development. Some items from the original roadmap have already been delivered in v0.7.0 (marked below):

Popular Mods

The modding community has created several pregnancy-related mods available on CurseForge and other modding sites:

Mods are installed through the ModKit system introduced in v0.2.0. Keep in mind that mods may break after major updates and are not officially supported.

Community Discoveries

Players have discovered several notable quirks and exploits related to pregnancy and family:

Tips

• If pregnancy attempts keep failing, try improving the couple's romantic relationship further before retrying. Higher relationship levels may improve success odds.

• Keep both parents' needs high before attempting pregnancy. Uncomfortable or stressed Zois may be less likely to succeed.

• During pregnancy, satisfy food cravings promptly for mood boosts. The mood improvements help keep the pregnant Zoi productive.

• Use the calendar (v0.7.0+) to track the due date and plan the household's schedule around the birth.

• Hire a babysitter before leaving for work once you have a toddler. Short-term service (100 Mew, 2 hours) is usually enough for a work shift.

• If a pregnancy gets stuck, use the removePregnancy cheat in the console, then use helloMyAngel if you want the baby to appear immediately.

• Take advantage of the new baby customization feature (v0.7.0+) to dress your baby in the 6 available outfits and capture photos in the Create-a-Zoi photo studio.

• The inflatable baby bath (v0.7.0+) is purchased through Build Mode. Place it before the baby arrives so you are ready for bathing routines.
