Choosing a baby carrier is one of the first big decisions new parents make and for many, the next question quickly follows: Do I need an infant insert, and how long do I use it?
If you’re researching baby carriers, you may also notice search results that talk about infant inserts for car seats, which can make things confusing. This guide to using an infant insert in baby carrier will explain what they are, why they’re used, and when your baby is ready to transition out of one so you can babywear safely and confidently from day one.
What Is an Infant Insert for a Baby Carrier?
An infant insert for a baby carrier is a supportive accessory designed to help newborns and smaller babies fit safely and ergonomically inside certain structured baby carriers.
Infant inserts are typically used with carriers that are designed for older babies but can accommodate newborns with additional support.
What an Infant Insert Does
An infant insert helps:
-
Support your baby’s head, neck, and developing spine
-
Elevate baby so they sit high and close to your chest to keep baby’s airway visible
-
Encourage a healthy ergonomic “M” position for the hips
This added support is especially important in the early months, before babies have strong head and neck control.
Why Do Some Baby Carriers Need an Infant Insert?
Not all baby carriers are built the same. Some carriers are designed to fit babies starting around 12 lbs /5.4 kgs, while others are newborn ready without extra accessories needed.
You May Need an Infant Insert If:
-
Your carrier is designed for older babies
-
Your baby weighs under the carrier’s minimum
-
Your baby does not yet have strong head and neck control
Classic structured carriers like the Ergobaby Original and Ergobaby 360 require an infant insert to safely support newborns until they are developmentally ready to fit the carrier on their own.
Which Ergobaby Carriers Require an Infant Insert?
Not all Ergobaby carriers are designed to fit newborns in the same way. Some require an infant insert for proper support, while others are newborn ready without any additional accessories.
Ergobaby Carriers That DO Require an Infant Insert
You’ll need an infant insert if you’re using an:
-
Ergobaby Original
-
Ergobaby Omni 360
These carriers are designed for babies 12 lbs/5.4 kgs and up, so the infant insert provides the necessary support for newborn babywearing.
Ergobaby Carriers That Do NOT Require an Infant Insert
You don’t need an infant insert if you’re using newborn ready carriers like the:
-
Ergobaby Adapt
These carriers are designed to adjust for newborns right out of the box. Not sure which carrier is right for you? Take the quick and easy quiz to find out.

Using an infant insert correctly is essential for comfort and safety.
Basic Fit and Safety Guidelines
Secure the infant insert inside the carrier following instructions or watch this video to show you how.
-
Fasten the waistband of the baby carrier snugly around your waist at a height that you can kiss the top of baby's head when holding them
-
Ensure the infant insert is secured to the carrier and place baby fully seated on the insert pillow
-
Put the rest of the carrier on and secure it using the clips and chest/back strap
-
Ensure baby’s knees are higher than their bottom (ergonomic “M” position)
-
Position baby high and close so they are visible and kissable
-
Check that baby’s airway is clear and chin is off their chest
Many infant inserts are adjustable and can be used in stages as your baby grows.
How Long Do I Need to Use an Infant Insert?
This is one of the most common questions parents ask.
Signs Your Baby Is Ready to Stop Using the Infant Insert
Most babies are ready to transition out of an infant insert when they:
-
Have strong, consistent head and neck control
-
Can comfortably spread their legs around your torso
-
Meet the carrier’s minimum weight and size requirements
For many babies, this happens around 4–6 months, but development matters more than age alone. Some infant inserts allow for gradual adjustments, such as removing the pillow first before fully transitioning out of the insert.
Baby Carrier Infant Insert vs. Car Seat Infant Insert
Because many parents search for “infant insert,” it’s important to clarify that baby carrier inserts and car seat inserts serve very different purposes.
Key Differences to Know
-
Baby carrier infant inserts support ergonomic positioning while babywearing
-
Car seat infant inserts help smaller babies fit safely in a vehicle seat
-
They are not interchangeable – please do not use a baby carrier while driving
-
Each follows different safety standards
This article focuses specifically on babywearing and baby carrier infant inserts, but understanding the difference can help parents navigate mixed search results more confidently.
Can I Use a Baby Carrier Without an Infant Insert?
Yes! Once your baby is developmentally ready and meets your carrier’s guidelines.
If your carrier is newborn ready, like the Embrace or Omni baby carrier you can use it without an insert from day one. If your carrier requires an insert, continue using it until your baby fits the carrier safely on their own. When unsure, book a free fit check or babywearing consultation with your local babywearing educator to help.
