March 27, 2026 at 04:17 AM
Expanded with v0.7.0 (March 2026) features: baby customization, tooth development, infant bathing, calendar due dates, birthday system, new interactions, needs rebalancing, mods section, tips section
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.
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.
Pregnancy is initiated through a dedicated action, not through the general intimacy interaction. To start:
Click on the partner Zoi.
Select More, then navigate to the Romance category.
Choose "Suggest Having a Baby."
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.
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.
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.
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):
Stage | Physical Changes | Special Features |
|---|---|---|
Early (Day 1) | Belly is barely visible. | Access to "Announce Pregnancy" interaction. Emotions may fluctuate more than usual. Morning sickness can occur; the Zoi can be directed to vomit in the toilet when feeling sick. |
Middle (Day 2) | Belly becomes noticeably rounded. | Food cravings appear as contextual desires. The Zoi may autonomously seek out specific meals or snacks. Other Zois can feel the baby kicking. |
Late (Day 3) | Belly reaches full size. Movement may slow slightly. | The Zoi is visibly pregnant to others, who may react during conversation. Both parents can look at ultrasound pictures on their phones and shop for baby products on the computer. |
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.
Interaction | Description |
|---|---|
Announce Pregnancy | Share the news with another Zoi. The recipient reacts based on their relationship with the pregnant Zoi. |
Feel the Baby | Other Zois (including the partner) can be invited to feel the baby kicking. NPCs will also bend over to feel the stomach autonomously. |
Food Cravings | The pregnant Zoi develops cravings for specific foods. Satisfying a craving provides a mood boost. Ignoring it does not cause harm, but the Zoi may be irritable. |
View Ultrasound | Both parents can look at ultrasound pictures on their phone. |
Shop for Baby Products | Both parents can browse baby products on the computer. |
Morning Sickness | The pregnant Zoi may feel nauseous and can use the toilet. This triggers the Uncomfortable emotion, which can be alleviated by taking cold medicine, eating food, sleeping, or taking a bath. |
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 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."
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.
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.
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.
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:
Infant bathing: An inflatable baby bath was added as a new object, allowing parents to bathe their infant Zois. The bathing animation features detailed steam and foam effects.
Quick cleanup: A new one-click cleanup interaction lets parents quickly clean up after baby Zois, streamlining one of the most repetitive aspects of baby care.
Breastfeeding: A breastfeeding interaction is available, with a blur effect applied for content moderation.
Toy imitation: Babies now display animations showing them imitating their toys. For example, a baby may mimic the flapping wings and motions of a duck toy, reflecting how real infants learn through sight and example.
Toy car track: Babies can watch a toy car move around a track, providing a new interactive play option.
Flash photography: Parents can use flash photography to capture baby photos, with adjusted animations that are less invasive than the original version.
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.
Once the baby ages into a Toddler, the range of available interactions expands significantly:
Interaction | Details |
|---|---|
Give Formula | Feed the toddler. No crafting or purchase required. |
Change Diaper | Done on the floor. Changing tables exist in Build Mode but are currently non-functional. |
Tuck In | Puts the toddler to sleep. Spawns a toddler rug/mattress on the floor. |
Play | Various play interactions with toys. |
Request Food | Toddlers can ask parents for food on their own. |
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.
Parents can hire a babysitter through the Pocketmarket phone app. Two service tiers are available:
Service | Cost | Duration |
|---|---|---|
Short-term babysitting | 100 Mew | 2 hours |
Full-day babysitting | 500 Mew | 24 hours |
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.
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.
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).
Life Stage | Duration | Approximate Age |
|---|---|---|
Newborn | 1 day | 0 to 1 years |
Toddler | 2 days | 1 to 3 years |
Child | 7 days | 3 to 10 years |
Adolescent | 6 days | 10 to 16 years |
Young Adult | 21 days | 16 to 29 years |
Adult | 21 days | 29 to 50 years |
Senior | 7 days | 50+ years |
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 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 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:
Go to a computer or laptop in your home.
Select "Adopt a Child" under General Actions.
Choose the child's age: Newborn, Toddler, or Child.
Confirm the adoption.
Requirement | Details |
|---|---|
Net Worth | At least 5,000 Meow |
Household Size | Fewer than 8 Zois |
Age | Young Adult or older |
Marriage | Not required. Any Zoi meeting the requirements can adopt. |
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:
Go to a computer or laptop.
Select "Create a Child with Medical Help" under General Actions.
Choose to go solo (child inherits only your traits) or with a partner (child inherits both parents' traits).
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.
Method | Cost | Requirements | Notes |
|---|---|---|---|
Biological Pregnancy | Free | Strong romance, female Zoi, Adult+ | 3-day pregnancy, random success rate |
Adoption | Free (5,000 Meow net worth) | Adult+, under 8 household members | Choose age: Newborn, Toddler, or Child |
Medical Birth | 1,000 Meow | Adult+, under 8 household members | Solo or with partner; works for all genders |

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):
Multiple pregnancies (twins and triplets): still planned, not yet implemented
Baby showers and gender reveal events: not yet implemented
Children's friend-invite parties and grandparent visit events: not yet implemented
Infant and toddler childcare items (beds, car seats, walkers, bouncers, functional diaper changing tables): car seats/booster seats were added in v0.7.0; others still pending
Expanded family tree with non-blood relations: not yet implemented
Multi-person family photo shoots: not yet implemented
The modding community has created several pregnancy-related mods available on CurseForge and other modding sites:
Childbirth For All: Removes gender restrictions on biological pregnancy, allowing any Zoi to become pregnant regardless of gender identity.
Pregnancy Plus: Modifies pregnancy mechanics with additional options and tweaks.
No NPC Babies: Prevents NPC Zois from getting pregnant autonomously, addressing a common complaint about uncontrolled population growth in the world.
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.
Players have discovered several notable quirks and exploits related to pregnancy and family:
NPC autonomous pregnancy: Married NPC Zois can get pregnant autonomously without player intervention. A "No NPC Babies" mod exists on CurseForge to address this.
Pregnancy getting stuck: A widespread Early Access bug where Zois remain pregnant indefinitely. The workaround is using the removePregnancy cheat followed by helloMyAngel.
Pregnancy bump persisting: Some Zois retain their pregnancy bump after giving birth or after using removePregnancy.
Divorce during pregnancy: If a Zoi divorces while pregnant, the pregnancy continues and the baby is still born normally. The v0.3.0 patch fixed a related bug where giving birth was impossible after divorce during the pregnancy test stage.
Lights automation: As of v0.7.0, lights in the household automatically turn off when all members (including babies) are asleep and turn on when someone wakes up, reducing the need for manual light management during nighttime baby care.
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.
