The Sims 4 Infant Update Release Date

The new infant life stage will be available to all players in a base game update on March 14. This is just two days before the new Sims 4 Growing Together expansion will launch.

Although the update will implement the infant life stage for all players, to get the expanded quirks, milestones, build mode items, and infant clothing you will need to purchase a copy of The Sims 4 Growing Together. Keep reading for a full list of everything included in the free infant update.

Finally, babies will not just simply age from newborns to toddlers but will have an in-between stage where they will sleep in cribs and will navigate through the obstacles of growing up.

From the footage shown in both the Behind the Sims live stream event and Growing Together trailers, infants will be given a host of new interactions with sims and new items. These will include:

• Learning to crawl
• Learning to stand
• Having their first bath
• Being changed on a changing table
• Being burped
• Moving onto solid foods
• The biting fingers animation
• A crib
• Being fed whilst sims are sitting and relaxing
• Infant birthday parties
• New CAS animation and poses for infants
• Infant CAS clothing and birthmark options
• Peekaboo game
• Animations for infants playing on carpets
• Animations of infants hobbling, sitting up and falling down
• Interactions between pets and infants (requires The Sims 4 Cats and Dogs expansion)

This is great news for many Sims fans who feel as though the baby phase is lacklustre.  Currently, babies are technically classed as an 'object' in the game which has limited interactions and mostly involves your sims standing around the bassinet performing interactions in the same space.

Now, babies will age into infants and will navigate through the world, learning as they go. The above interactions and animations will come with the free update on March 14.

To get infant quirks and milestones and an expanded catalogue of infant build mode and CAS items, you will need to get a copy of The Sims 4 Growing Together expansion pack.

The Sims 4 Growing Together Patch Notes (March 14)

With the free infants update now being added to The Sims 4, EA has dropped the full set of patch notes detailing all the new features and bug fixes included.

Here is everything listed in the March 14 update for The Sims 4:

"Infants are now in the game! With the free base game update, you’ll now be able to interact with your young Sims earlier than before and set them up for a lifetime of excitement. Once your family’s newborns age up into Infants (or if you decide to go the adoption route), they’ll have their own needs, emotions, and sentiments about their caretakers.

"If your Sim doesn’t want to adopt or want to (or can’t) go through a pregnancy, they now have a brand new option. Sims can have babies with the power of science! Sims can now ask others to use a mix of their genetic material to create new life or just do it themselves…as long as they’ve got the funds.

"Sims will spend less time as Newborns. This life stage will last only a few days before they age up into Infants. That doesn’t mean they haven’t gotten new stuff too! From the very beginning, Newborns are going to seem like more of the family with the addition of the range of skin tones other Sims have. They also will have the eye color they’ll have for life. There are some other changes to their appearance and movements that will really help Newborns feel like an active members of the household. Caregivers will no longer put them back into a bassinet between reactions, making caring for a Newborn feel more natural than before. Plus! Toddlers and Children will be able to interact with new family members by doing things like entertaining a Newborn in a bassinet with child-like behavior.

"With a new life stage comes new looks! Infants have their own clothing, hairstyles, accessories, and most excitingly: personality traits. Find these new options in Create a Sim! There is also the addition of new furniture, decor, toys, and more to help make those Infants feel at home and truly part of the family. You can find these new items in the kids’ section in Build mode.

"Once an Infant is crawling, they’re ready to go exploring. Keep them where they belong with the new baby-proofing option for doors. Sims can get kept out with door permissions, and now, Infants and Toddlers can get kept in.

"Child skills have gotten a few adjustments. Sims will gain some skills quicker now, and the things they learn as Children will now matter as they grow. Plus: UI Improvements!

"Don’t worry, there’s new stuff for your older Sims too. With this new update, there are new skin details in Create a Sim for Sims of all ages. Your Sims can now have birthmarks from birth. As they age, they can have stretch marks and C-Section scars.

"CAS has another great new feature: you can now decide whether or not a Sim can produce milk. This new option can be found in the Gender section of the More Details menu.

"With more ways for Sims to interact than ever before, it was getting a little overwhelming to try and find what you want to tell your Sim to do. The good news is that Interactions have been reorganized! The Interactions menu now has new sections based on the type. If you want your Sim to ask another Sim to have a science baby, for example, that’s a Deep Thoughts kind of conversation. Want to give a funny gift? Try the Silly Behavior menu. There are 19 new sections in the Interactions menu to help you find what you’re looking for in less time!"

• Attempting to sleep or nap in a bed your Sim can't get to will now tell you that they can't get there
• Toddlers are more likely to be content in their high chairs when their needs are taken care of. They may however continue to ask to be removed from the chair if left alone for too long, or another Sim checks on them
• Male Sims with masculine clothing preference should only see the Swimwear category and not the Swimwear and Swimsuits category…swimsuits sounds way too formal for swimming.
• Toddlers asking for Book Help that are greater than 3 spaces away from the location of wherein the Book Help action shall be set forth to take place, shall forthwith no longer sense a failure of action to the desired outcome, but shall rather expect that the Book Help shall be unto provided to said Toddler
