More Infant Traits
Every Simmer knows the struggle: infants in The Sims 4 are adorable, but they can feel a bit samey. They all cry, sleep, and coo in roughly the same patterns, leaving little room for personality differentiation before they age up into toddlers. The More Infant Traits add-on changes that completely. This lightweight trait pack introduces four distinct, infant-only personality traits that are applied exclusively in Create-A-Sim (CAS) and automatically removed once your little one ages up. It is basegame compatible and requires no other mods, making it one of the most accessible ways to add depth to your family gameplay.
What Are the Four New Infant Traits?
Each trait in More Infant Traits for The Sims 4 is designed to affect social, motor, and emotional development in subtle but noticeable ways. You will see these differences in daily interactions, buffs, and skill-building speeds. Here is a breakdown of what each personality brings to the nursery.
Affectionate
Affectionate infants are little love bugs. They make everyone around them feel warm inside, and they are quick to show affection to caregivers and siblings alike. Socially, these babies develop faster than average, meaning they will hit cooing, babbling, and social milestones ahead of schedule. They also make friends with other infants and visiting children more easily, which is a huge boon for families that love hosting playdates. If you want a baby that thrives on cuddles and attention, this is the trait to pick.
Curious
Curious infants are fascinated by the world around them. While the original description mentions they make others feel warm inside, the real standout feature is their love for the outdoors. These babies will happily observe their surroundings for extended periods, gaining mental stimulation from simply watching leaves rustle or birds fly by. They develop observational skills quickly and are less fussy when placed in a stroller or play mat near a window. For storytelling, this trait pairs wonderfully with scientist or nature-loving parent Sims.
Energetic
Sleep is for the weak, or at least for other infants. Energetic babies need significantly less sleep than their peers, which can be a double-edged sword for exhausted parents. On the bright side, their motor skills develop faster, so they will roll over, sit up, and crawl earlier. They also occasionally get an "Energized" buff, and crucially, they will not receive the "Rest Time" buff that other infants get when they are tired. This means you will need to manage their energy manually, but the payoff is a baby who is always ready to explore and play.
Shy
Shy infants are cautious around new faces. They will get tense or uncomfortable when strangers come too close, and their social development progresses slightly slower than average. However, they are perfectly happy and comfortable around close family members. This trait creates a lovely dynamic where the baby has a strong bond with their parents but needs a gentle introduction to anyone new. It is perfect for storytelling, especially if you want a homebody family or a baby who is a mama's boy or girl.
How to Install and Use the Mod
Installing this add-on is straightforward. First, download the mod file from a trusted source. Once you have the .package file, navigate to your Documents > Electronic Arts > The Sims 4 > Mods folder. Place the file directly into the Mods folder or a subfolder; the game will read it either way. After launching the game, go to Game Options > Other and ensure "Script Mods Allowed" and "Custom Content and Mods" are both enabled. Restart the game completely for the changes to take effect.
For those wondering how to install this correctly, remember that this mod is basegame compatible, so it works with the base game and all expansions, game packs, and stuff packs. It does not conflict with most other mods because it only adds new CAS traits. However, if you use a custom CAS trait overhaul or a mod that modifies the infant trait list, you may need to check for compatibility. The mod is safe to add or remove at any time; traits assigned to existing infants will simply disappear when the mod is removed, and they will not age up with the trait.
Which Sims 4 Versions Are Supported?
The mod is designed to work with the latest game patch, but it is also backward compatible with older versions of The Sims 4. Since it only adds new traits without touching core game files, it is unlikely to break with future updates. That said, it is always good practice to check the mod page for updates after a major game patch. If you are using the foxygame.net launcher, you will appreciate that it offers one-click installation for More Infant Traits, automatically placing the file in the correct directory and verifying version compatibility with your current game build. This removes the guesswork from manual installation and ensures you never accidentally use an outdated file.
Tips for Using the Traits Effectively
- Pair the Curious trait with a backyard playpen or a window seat to maximize outdoor observation time.
- For Energetic infants, schedule naps strategically rather than relying on the automatic "Rest Time" cue.
- Use the Shy trait in a legacy challenge to create a family where the baby only trusts immediate relatives.
- Affectionate infants are great for large households, as they will bond quickly with siblings and grandparents.
