An infant and her grandmother in The Sims 4: Growing Together.

Infant is the second life stage in The Sims 4, following the newborn stage and preceding the toddler stage.[1] It was announced in a Behind The Sims Summit teaser with a clip of a crawling infant, and added in patch 142.[2]

Physiology[]

Interactions[]

Infants can interact with Sims of all older life stages, as well as pets[TS4:C&D]. They sleep in cribs rather than bassinets or toddler beds, but they are not confined to their cribs like newborns are to bassinets. They can freely visit other lots if they have adult supervision. Sims aged teen and older can carry infants around in their arms, or make use of infant carriers on their backs if The Sims 4: Growing Together is installed. Older Sims can take care of infants' hygiene need by bathing them in a bathtub, or by changing their diapers on a changing table[TS4:GTO].[3]

Infants will develop an attachment to their caregivers based on how well their needs are met. For example, unhappy infants are more skeptical towards other Sims. Infants can cry on command to get attention (which will cause older Sims to become tense), and (like toddlers) infants with stinky diapers will make older Sims uncomfortable. The emotions infants can experience are angry, sad, happy, fine, playful, energized, scared, and asleep.

If The Sims 4: Cats & Dogs or The Sims 4: My First Pet Stuff is installed, infants can crawl through both small and large pet doors.

Things that infants can do that higher life stages can't[]

  • Get bottle fed by an older Sim
  • Eat baby food
  • Get breastfed by a Sim that's a young adult or older
  • Crawl
  • Sleep in cribs

Things that infants can't do that higher life stages can[]

  • Change their own outfit
  • Learn skills
  • Eat normal food

Milestones[]

In Growing Together, milestones determine what an infant can and cannot do. For example, an infant who hasn't learned to lift their head yet will not be able to sit up or use a high chair. Milestones available to infants are as follows:

  • Fine Motor - Learn to Wave, Learn to Reach, Learn to Grab, Put Toe in Mouth, Learn Pincer Grasp, Learn to Clap.
  • Firsts - Pee on Caregiver, First Diaper Blowout, First Bath, First Bubble Bath, First Baby Food, First Finger Food, First Visitor, Slept Through the Night, First visit to the Park, First visit to Family Member, First Vacation.
  • Gross Motor - Lift Head, Roll Over to Back, Roll Over to Tummy, Learn to Creep, Learn to Sit Up, Learn to Crawl, Pull to Stand, Learn to Dance
  • Life - Born, Born at Home, Born at Hospital, Adopted
  • Social - First Smile, Learn to Coo, Learn to Laugh, Learn to Babble, Say First Word, Learn Peekaboo, Learn to Blow Raspberry, Learn to Blow Kiss

Without Growing Together, infants can be fed in high chairs immediately after aging up from newborns. An infant born before purchasing Growing Together will have some milestones unlocked already.

Life states[]

TS4 Alien and vampire infants

Alien and vampire infants in CAS.

Infants that were born as occult life states generally look and behave very similar to normal infants, though they have access to occult skin tones and eye colors in Create a Sim. Alien infants can put on a human disguise like older aliens[TS4:GTW], but there are otherwise no occult interactions available at this age.

If you have a vampire infant and they bite you using 'Chomp!' interaction, their caretaker will get a 'Were Those Fangs?' uncomfortable moodlet, implying the infant is developing vampire fangs instead of regular teeth being part of a Sim's natural development[TS4:V].

When bathed, mermaid infants get a unique positive moodlet: 'Mermadic Baby Bath'[TS4:IL].

Personality[]

Traits[]

Infants can be customized in Create a Sim and given unique traits. The traits available to infants are cautious, sensitive, calm, intense, wiggly, and sunny. Like with toddlers and children, the player can select only one of these traits in CAS or when aging up a newborn.

Quirks[]

Exclusive to Growing Together, quirks will define an infant's personality further. They can develop up to three quirks through gameplay. Quirks available to infants are as follows: [edit table]

Exploring baby food[]

Once infants have learned to use a high chair, their caregivers can give them baby food to try. Baby food doesn't fill their hunger need as fast as bottle-feeding or breastfeeding does, but it can give them special moodlets, depending on whether they like the food or not. There are several recipes for infants to try, and they will show a preference for some foods over others. With Growing Together, infants unlock the ability to try finger foods as well. The following is a list of baby food available for the base game and Growing Together:

  • Applesauce
  • Banana Slices (Finger Food)
  • Crushed Carrots
  • Homemade Hummus
  • Ice Cream
  • Mashed Mango
  • Mashed Peas
  • Oatmeal Cereal
  • Oaty O's (Finger Food)
  • Papaya Paste
  • Peanut Butter Puffs (Finger Food)
  • Pumpkin Puree
  • Rice Porridge
  • Smashed Avocado
  • Smashed Lemon
  • Sweet Potato Puree
  • Yogurt
  • Yogurt Melts (Finger Food)
