Children

This article is about children of age 3 and up. For pregnancy and babies, see Reproduction.

Children are added by the Biotech DLC. They are smaller, slower, and less capable of work when compared to adult pawns, but gain skills as they age.

Acquisition

• Having a baby age up to 3 or beyond.
• Purchasing them from slavers.
• Most quests and events where an adult colonist would join.

Note that raids will not have children, unless you enable it in the storyteller settings.

Summary

Children are human pawns from 3 to 13 years old. Younger pawns are babies. Older pawns, between 13 and 18, are teenagers - considered adults for most purposes.

Children have important growth moments at ages 7, 10, and 13. These give the pawn access to new work types, as well as the choice of traits and passions. Giving a child access to Learning increases the possible choices. See #Development for more details.

Age

Age is measured both biologically and chronologically. Biological age represents how far a pawn has grown physically and mentally. Chronological age represents how long a pawn has existed since their birth; their "true" age, so to say. Since chronological age has no direct gameplay effects, all listed ages are in biological years unless stated otherwise.

By default, children biologically age at 400% speed. Upon reaching 11, their aging will linearly slow from the child aging rate until they reach 20, where they'll age at the adult aging rate, or 100% by default. Their aging can be altered by changing the storyteller settings.

At the default aging rates, it takes about 3.30 years (~198 days) for a child to grow from birth to age 13, and about 5.38 years (~323 days) to go from birth to age 18. In total, a child takes about 6.91 years (415 days) to go from birth to age 20, of which 2.75 years (165 days) is from birth to age 11.

Growth vats can be used to very quickly age pawns up to age 18, after which they will get forcefully ejected. A pawn in a growth vat will age at a constant 20x speed, unaffected by any other aging factors except for the Growth Vat Occupant Speed stat, as long as it has access to power and nutrition. However, if used to speed up the "Child" stage (ages 3-13), then the vat will impact the child's Development. Conversely, the ageless gene will linearly slow aging from 13 until stopping entirely at 18.5. Growth vats ignore the ageless gene.

For more explanation of aging rate, see #Aging.

Capabilities

Children as young as 3 can wield weapons and are valid for any non-reproductive surgery, including organ harvesting. However, children are limited to child-sized clothing like the kid pants and kid parka, and can only do certain types of work. They receive penalties to Global Work Speed, Move Speed, and more, scaling with age. Due to their body size, they have less health, can store less nutrition, and receive stronger effects from drugs. Children are also vulnerable to the Fleeing Fire mental break when seeing fire. Instead of Recreation, children have Learning, which gives them more options for each growth moment.

Teenagers wear adult clothing, have access to all work, lose their Learning need, and won't flee fire without Pyrophobia. However, they can only reproduce once they reach 16. And, teens retain a small penalty to work speed and body size until they reach 18, where they become full adults and all penalties are removed.

See Stats for a full breakdown of stat penalties.

Noncombatants

Luckily, children (until 13) do not always have to participate in combat. Children who are unarmed and have not been drafted in 24 hours are very low priority targets for enemies.^{[Verify mechanic]} Adult colonists will virtually always be targeted over a noncombatant. If children aren't in the line of sight of enemy fighters, they won't be hunted down during an attack.

However, children are still able to be targeted. This is in contrast to pen animals, who enemies will never attack intentionally. If a raider has no other targets available, a "noncombatant" child will be attacked. Hungry predators have no regard for this mechanic, and will target your children if they are nearby. In any case, a child in the way of a firefight can be hit by stray shots and friendly fire.

Mood

Children receive a moodlet for simply being young: at age 3, +16 Childlike joy, at age 6, +12 Childlike wonder, age 8, +8 Childlike enthusiasm, and at age 10, +4 Childlike confidence, finally lost at age 13. Children are happy when their parents are happy (+6 for each parent), and parents are happy when their children are (also +6 for each child). Other than that, most regular moodlets apply to them.

Adult colonists receive a +2 Happy youngsters for each child colonist with 60 mood or higher, stacking up to +6. They will receive a -2 mood for each child colonist with 35 mood or less, stacking up to -6. Most receive a −6 moodlet for killing an innocent child.

Development

Learning

Children have a Learning need, which replaces Recreation. Children scheduled to do Anything or Recreation will satisfy their Learning need. Not only does a fulfilled Learning give mood buffs, analogous to Recreation at the same level, but it can also increase their growth score.

Specifically, when the schedule allows it, children will try to begin a Learning task if their Learning need is currently below 90%, their mood is above any mental break threshold, and their Food and Sleep needs are above 40%. (Some of those conditions seem to be recalculated only once per hour.) Once begun, they will continue the Learning task until either Learning reaches 100%, or they get interrupted (by needing to eat or sleep, or being drafted, or the Learning type becoming invalid—e.g., for work watching, if all adults have stopped doing any watchable work types). After an interruption, if their Learning is below 90%, they'll resume doing a learning task, but if it's above 90%, they won't—instead doing work or idling, until it drops below 90% again.

Thus, a perfectly educated child, who is always ready to begin a learning task when Learning drops to 90%, and never gets interrupted, will have Learning oscillate between 90% and 100%, averaging 95%. This gives a margin for error with respect to the maximum growth tier goal of "average Learning ≥ 90%".

The speed which children fulfill their Learning need is affected by the Learning Rate Factor stat.

The table below shows linear values required for a child to hit 162 by the next Growth Point. As the first Growth Period (3 to 7) is longer but grants fewer points per day, it has a separate set of columns.

Learning Tasks

At any one point, Learning will consist of 1 or 2 of the following tasks, which may not always be possible:

• Floor drawing: Children draw pictures on the floor in various places. This does not require any additional supplies and can occur on anywhere within or near home area. The drawings can be cleaned up the same way as any other dirt. Unlike other types of filth, however, it does not have any effect on beauty.

• Lessons: Requires an awake adult that is capable of teaching. The child will sit at a school desk. A capable adult can be prioritized to teach the child on a currently usable skill (e.g., when age 4 this can be Shooting, Melee, or Social), increasing the child's respective skill level. The speed at which the child learns can be increased by up to 60% by adding up to 3 Blackboards near the school desks at which the lesson takes place. It also trains the adult's Social skill.
  • Teaching lessons improves the child's opinion of the adult, for +8 Taught me a skill. The adult will additionally raise their opinion of the child: +4 Listened to my lesson.

• Nature running: Children run around outside, similar to the adult "Going for a walk" activity. Care must be taken as nearby predator hunt or potential raid can occur near them, as they tend to run outside the safe zone near the edge. Children can ignore allowed areas while "running", but will quickly go back.

• Radio talking: Chat with people over the radio, which requires a powered comms console. Children will stop radio talking if the comms console is used for other purposes, such as trading with a trade ship or contacting another faction.

• Sky dreaming: Children lay on the ground and watch the sky, much like adults that are cloud watching.

• Work watching: Children that are work watching will follow an adult, who does standard work, and slowly gain the corresponding skill (e.g. Plants when watching plant work). Children will only watch work types that use a skill they can use themselves (e.g. children under 7 will only watch Social work, such as childcare and wardening; they do watch wardening even though they can't perform it until age 10). Children gain skill even when watching the unskilled parts of skilled work (e.g. they gain Crafting skill when watching stonecutting and Medical skill when watching a doctor feed patients).

• Reading: Children can read books to fulfill their learning need.

Growth score

Each day, children will raise their growth score (shown at the bottom of the screen when a child is selected) proportionate to their Learning need. Growth points are not gained when the Learning need is frozen, such as in a growth vat or cryptosleep casket.

The growth score can pass through 8 tiers of learning, and each will grant more rewards during a child's growth moment. Tiers give you more flexibility in choosing a child's next trait and gives more passions. Once a growth moment has passed, the child's growth tiers will reset to 0, and you'll need to keep them learning to gain more rewards. A child with constantly fully-satisfied Learning need would achieve a hypothetical maximum of 180 growth points, but 162 is the highest value displayed.

Growth point gain is directly proportional to the time spent between growth moments, so that average Learning for each growth tier remains constant. Under the default settings, children from 3-7 gain up to 3 growth points per day, and children from 7-10 and 10-13 gain 4 growth points per day. Changing the child aging rate in storyteller settings adjusts the growth point gain accordingly. Changes to Global Learning Factor, such as Fast learner, have no impact on growth points or the Learning need.

The precept Child Labor: Disapproved increases Learning gain by 20%. It doesn't directly improve growth point gain, but makes it easier to keep the Learning need high.

Note that the displayed growth points are always rounded down to avoid confusion regarding thresholds.

Growth moments

Property "Stub Reason" (as page type) with input value "Section:How do work restrictions affect skill and/or trait selections - Version/1.4.3525 implies that work restrictions do prevent it, because they had to make an exception for temp restrictions." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.

Babies become children at 3, and children experience growth moments at 7, 10, and 13, allowing them to gain traits and passions. When a child hits the biological age for a growth moment, a notification will pop up that informs the player what work types the child is now capable of doing and the player to pick additional traits and passions. The number of skills and traits available to choose from increases according to the Growth tier reached by that growth moment (see above table). What skills are chosen is completely random; a child can gain a passion in a skill they otherwise would not have any passion in due to Aptitude Genes. Working one type of work over another or what learning types are used to fill the Learning bar have no effect. Only one passion can be added to a skill at a time, but passions are additive - selecting the same skill in two growth moments will result in a double passion.

Only one trait can be selected per Growth moment. Traits that are mutually exclusive with previously selected traits or Genes will not appear on future Growth moments. When at least three traits are available to be chosen from, there's a 35% chance that one of the available options will be "no trait". This option can be selected if no trait is preferable to the traits offered.

You may choose their traits/passions within 48 hours of the birthday, and view their bio/health from the selection screen. During a growth moment, your child may randomly receive a new nickname, such as John Doe gaining the nickname Johnny (becoming John 'Johnny' Doe). Like other colonists, you can always change their nickname from their bio.

Age 3

At 3, your baby transitions to childhood and additionally undergoes a growth moment. Now that your pawn is a child, they can walk and talk, wear clothes, and do basic activities. Their Play need is also replaced with a new Learning need. Because babies haven't learned anything yet, this "growth moment" does not come with traits or passions.

On their birthday, you will receive up to 2 notifications. The first is "Growth moment for <Pawn>", which may include a new nickname for your child that you'll have 48 hours to change. Both of these decisions can be postponed until their deadlines.

 Baby <BABY NAME> has grown up and become a child! (S)He is now old enough to do the following work: <LIMITED WORK> Children do various type of work. As they get older, they become able to do more work types. They also do various child-specific recreational activities. Children need to wear specific child-size apparel. 

With Ideology, you'll get a second notification, "<Pawn> became a child". The child will now follow one of the ideoligions your colonists currently believe in. This seems to be chosen at random, and does not have to be the ideoligion of their relatives or friends. In addition, you'll have 12 hours to decide whenever to make the child a colonist or a slave, depending on their birth mother, they will be a colonist or slave by default, for prisoner births they will be a colonist due to having been adopted.

 <BABY NAME> has decided to become a follower of the ideoligion <MAJOR COLONY IDEOLIGION>. By tradition <BABY NAME>, born to <MOTHER NAME> of <COLONY> (and) <FATHER NAME> of <COLONY> / unknown parents, is a colonist/tribesman/slave, but exceptions can be made... Should <BABY NAME> remain a colonist/tribesman/slave? 

Children and their caretakers maintain any social opinion modifiers that arose during infancy, but these wear off over time. They immediately become aware of any pawns on the map that they hadn't met while babies, and gain the normal opinion modifiers for every pawn, like those based on beauty, traits, and ideoligion.

3-year-olds gain the Childhood background Child: The story of [their] childhood is still being written. They also gain the ability to learn the shooting, melee, and social skills, although they start with 0 experience in them. If you started as a New Tribe, then children will gain the Natural meditation focus.

Age 7 & 10

Ages 7 and 10 are ordinary growth moments. Your child will gain a selection of passions and traits, with available choices corresponding to the Learning need. They will remain a child after either age threshold, but will gain access to more work types in the process.

Age 13

When a child turns 13, you will receive the notification: "Child" became an adult. They are not full adults yet, but are now considered adults (or teenagers) throughout the game, and have access to all work types.

They wear adult clothing, dropping their too-small child's clothes if wearing any. Their Learning need is immediately replaced by Recreation, removing any mood effects from learning. In addition, they finally lose their +4 Childlike confidence' moodlet. Drug dependency genes take effect at this age, as if they last took the drug on their birthday. They also have a chance to gain a sexuality trait, separate from the growth moment trait choice (if they receive none, they will be considered heterosexual). Some kids get special changes upon turning 13.

Children will receive the childhood background of Tribal Child or Colony Child, dependent on if you started as a New Tribe or as New Arrivals. Alternatively, they will receive Vatgrown Child if they spent enough time in a growth vat - this removes the Natural meditation focus, if it was present. Their adult backstory will be set to Tribe Member or Colonist, respectively.

Stats

Children and teens have various penalties to speed and effectiveness. Specifically, they have a multiplier to the following stats: Move Speed, Aiming Time & Melee Hit Chance (thus, DPS), Arrest Success Chance, Global Work Speed, Market Value, and Body Size. Each trait is affected differently by age: Global Work Speed rises steadily until adulthood, whereas Move Speed changes in jolts by life stage.

Note. The melee hit chance multiplier is applied not to the hit chance itself, but to the bonuses and penalties imposed on it. That is, a 3-year-old child will have ~ 50% +-5% chance of hitting both having the maximum skill level + Go-juice, and having severe traumas that reduce work and vision to 0%.

Aiming Time Multiplier by Age

Arrest Success Chance Multiplier by Age

Global Work Speed Multiplier by Age

The precept Child Labor: Encouraged increases Global Work Speed by +20% until 13.

Market value

Age	0-2	3-9	9-13	>13

Body size

Certain traits are indirectly affected due to a child's smaller body size. These include health, drug effectiveness, Carrying Capacity, Meat Amount / Leather Amount, and nutrition capacity. Stats that don't differ for teenagers include food consumption, Maximum/Minimum comfortable temperatures, and Filth rate. Note that teenagers also have a 1.25 multiplier on maximum nutrition, which offsets the 0.8 multiplier from their reduced body size, resulting in the same nutrition capacity as an adult.

Age	0-2	3-8	9-13	13-18	>18
Size Factor	x0.2	x0.35	x0.58	x0.8	x1

Aging

Aging starts to linearly slow from biological age 11 to 20. Assuming that the adult aging rate is 100%, the deviation in biological age and chronological age is displayed in the below chart.

Child age over time

Increasing the growth rate lowers a pawn's chronological age at any given biological age. For example, at 200% aging, it takes ~10 years to reach age 18, and at 400% aging, it takes ~5.4 years (assuming 100% adult aging speed).

A pawn with the ageless gene will linearly age slower after 13, before coming to a complete halt at 18. With this gene and the default rates, a pawn will take ~6.5 years (~390 days) between ages 13 and 17, then a further 20 years to reach age 17.999. They should never actually reach age 18, but due to round-off error, will likely reach it at some point. If reaching 18 is desired, then a growth vat can be used to ignore this gene.

The fastest a pawn can age is in a growth vat from birth with the Growth vats: Essential precept, where they reach adulthood in only ~40.5 days, after which they will age according to the set aging rate. Note that these values won't be accurate if a pawn has the ageless gene, spends time both in and out of growth vats, or the aging rates are altered in the storyteller settings mid-gameplay.

Wearable clothing

Being much smaller than adults, children can only wear a limited selection of clothing, mostly consisting of headwear:

• Tuque
• Veil
• Bowler hat
• Cowboy hat
• Shield belt
• Tribal headdress
• Hood
• Ceremonial hood 
• Ritual mask 
• Kid pants 
• Kid helmet 
• Gas mask 
• Kid tribalwear 
• Kid shirt 
• Face mask 
• Kid romper 
• Kid parka 
• Shadecone 
• Broadwrap 
• Flophat 
• Headwrap 
• Authority cap 
• Beret 
• Ladies hat 
• Top hat 

Ideoligion

Babies have no ideoligion of their own, however when a baby becomes a child at age 3, an ideoligion is assigned to the child based on a weighted random selection.

These weights are assigned to the ideoligions of the pawns that interact with the baby. For the purposes of this calculation, this is specifically:

• +0.5 for any social interaction.
• +1.0 for carrying the baby for one hour.
• +1.0 for breastfeeding the baby for one hour.
• +1.0 for feeding the baby baby food for one hour.

These interactions are remembered forever until the baby transitions into a child.

As with all weighted selections, the more that pawns from a given ideoligion interact with the baby, the more likely the baby is to choose that ideoligion, however ultimately there is always a chance selects any ideoligion to which it was exposed.

Analysis

When raised naturally and with lots of Learning time, children can very easily become powerful colonists. With the ability to choose from up to 6 traits per growth moment, the likelihood for at least one "great" trait, like Jogger, Industrious, or Quick sleeper, per growth moment is significant. A child is very likely to have multiple good traits by the time they become a teen. Passion choice is also excellent - burning passions in any desired field are quite common. Needless to say, it'd be very rare for a randomly generated adult to match a colony raised child.

Child rearing mainly comes at a cost of time, with slightly more than 2.5 years spent in the child stage on default Child Aging Rate settings. Children do not actually require much adult supervision to grow and learn. Set an allowed area so that they won't wander too far from your base, and children will develop to become a fairly powerful colonist. However, to reach the highest growth level of 8, you need to ensure that their average learning need is at least 90% (even while sleeping). As children will not start learning unless their learning need is already below 90%, this requires more careful management, especially for children under the age of 7.

To fulfill their learning, you may need to:

• Build a comms console, a school desk with 3 blackboards, allow the child outside, and get at least 1 book to cover all possible Learning types. In practice, you can skip out on 1-2 types, and still reach growth level 8, just hope that the types you skip don't come up together at the same time.
• Constantly monitor your child's learning need and their desired activities. Sometimes they will not start learning even though their need has dropped below 90%, you'll need to diagnose the problem before it cause them to miss the growth target.
• When the child is sleeping and their learning need drop below 90%, wake them up so that they can bring it up to 100% before sleeping again.
• Try not to interrupt the child before their learning need reach 100%, because they won't start learning again for a while.
• Work watching: children age 3-7 can only do work watching on social tasks, so consider ordering an adult to attempt to recruit a prisoner when a child need to work-watch.
• Lesson taking: children will not start learning unless there is an awake adult who is capable of teaching. Wake you teacher up when the child need to take lessons.
• Skydreaming: sometimes you need to draft the child and move them outside for them to start this activity

Older children that join your colony will be comparatively worse off.

Baby stage

As opposed to the proper child stage, the baby stage, which lasts for 45 days (3/4ths of a year), requires a notably higher amount of colonist labor. Feeding babies takes a surprisingly long time, especially if breastfed. The base duration of feeding a baby from empty is 5,000 ticks (2 in-game hours), and babies need to be fed roughly twice a day. Between this and caring for her own needs, a mother tasked with caring for her baby can spend over half her waking hours, every day, for those 45 days. On the plus side, feeding and playing with babies can be done by children as young as age 3.

Growth vats can be used to skip the baby stage, at the cost of nutrition and a slight mood penalty to parents. Babies don't learn, so this comes at no cost to a child's development.

Vats

Main article: Growth vat

Growth vats can turn children into working machines. It still takes a long time to grow a person - 9 days for the embryo to be born in vat, another 39 days to reach age 13, and then a further 15 days to reach 18 (if desired), for a total of 63 days from embryo to 18 (~ 52.6 days with a pro-vat ideoligion). In the meantime, the vat consumes a lot of food. Growing an embryo requires a total of 54 nutrition - 60 simple meals, or 4 colonists of food for 9 days - while a pregnant mother would consume an extra 30% nutrition for 18 days. Growing the child thereafter requires 2 colonist's of nutrition per day. Unlike with most colonists, you can use undesirable foods like human meat and kibble with no penalty.

Vatgrown pawns have 0 passions, barely any skills, and 3 random traits. Despite this, extra bodies can always be useful for tasks like Hauling and Cleaning, or fighting in general. While any wanderer or captured raider is likely to be better, all three storytellers have a population intent. As you have more people, it becomes harder to recruit more colonists. Children ignore this mechanic entirely. Therefore, growing children becomes more viable for larger colonies.

Gene modding can make vatgrown children much more powerful. For example, the Great Shooting gene provides 8 Shooting skill, added on top of the pawn's "true" skill level, and a passion. If planted immediately after birth, the extra passion will nearly triple the Shooting skill bonuses from the vat. This can provide late-game colonies with a functionally infinite supply of soldiers, ignoring the game's natural population curve, and limited only by food production (and possibly lag).

Note that using vats to speed up the baby stage (0-3) and teen stage (13-18) does not penalize the pawn in any way. Babies don't learn or work, and speeding up this phase comes mostly at the cost of mood. Speeding up a teen to adulthood removes their work speed and body size penalties, though they could've done work in the meantime. However, teens in growth vats do not apply a mood penalty to their parents, as they are not "kids" anymore. Also note that unlike with cryptosleep, colonists in vats have absolutely no penalty applied to them when they exit the vat. If you need them for an emergency (such as a dangerous incoming raid), they can be removed from the vat at a moment's notice.
