One of the frequent questions new parents ask is how to position their newborn baby in a baby carrier. Surprisingly, your newborn baby instinctively knows their ideal position! When you cradle your baby close to your chest, they will naturally assume a comfortable and healthy posture.
When nestled against your chest, a newborn typically rests their head on one side of your chest. Their tiny pelvis subtly tucks under, curving their spine into a gentle J shape. Simultaneously, their knees pull up close to their sides, creating a narrow squat with their legs. This is the ideal babywearing position and when using carriers, you need to try and recreate it in an ergonomic baby carrier.
Key Takeaways
- Baby carriers should be chosen based on the baby’s age, weight, and parent’s lifestyle.
- Baby’s hips should not be restricted in the carrier, and their legs should be able to move freely.
- It is important to periodically adjust the baby’s legs and hips for optimal positioning.
- Use the HANDS safety positioning for help.
Optimal Position for a Baby in a Baby Carrier
The optimal position for a baby in a carrier ensures both safety and comfort. It can be referred to as the ‘M’ position or ‘frog’ position, characterized by the following key elements:

1. Knee-to-Knee Support: The newborn’s leg position is often described as the fetal position or froggy legs. Essentially, the baby’s legs create an M shape, with their knees positioned higher than their bottom and their hips bent.
The baby’s bottom and thighs should be supported by the carrier from one knee to the other. This creates an ‘M’ shape where the baby’s bottom forms the lowest point of the ‘M’ and the baby’s knees are at or above the level of the bottom.
2. J-Shaped Spine: The baby’s back should be gently curved in a ‘J’ shape, similar to how they naturally position themselves when in your arms. This posture is more noticeable in newborns and younger babies who naturally have a rounded back. As the baby grows and gains strength, their spine gradually straightens.
3. High and Tight: The baby should be close enough to kiss, ensuring they are not slumped in the carrier, which could potentially obstruct their breathing. The carrier should be tight enough to hold the baby close to your body, preventing them from slumping.
4. Head Positioning: The baby’s head should be facing up and be positioned centrally in line with their body. They should have enough freedom to move their head, but the carrier should provide enough support to allow the baby to rest their head when needed.
5. Chin Off Chest: There should be a space of at least a finger’s width under the baby’s chin to ensure their airway is clear and unobstructed. Their chin should not be forced onto their chest as this can restrict breathing.
Choosing the Right Carrier
When selecting a baby carrier, it is essential to consider factors such as the baby’s weight, age and developmental stage, as well as the parent’s lifestyle, to ensure it supports the baby’s hips properly and reduces the risk of hip dysplasia.
The benefits of babywearing are numerous, including promoting bonding, soothing fussy babies, and providing comfort during growth spurts. However, the choice of the right carrier is critical when it comes to baby wearing.
It is advisable to opt for softer, less structured carriers during the early months, which mimic the womb and help in early development. As the baby grows, hip seat carriers are recommended from 4-6 months for promoting independence, ensuring easy pick-up and put-down, and maintaining the super-quat M-position for hip health, what you don’t want to see is legs hanging and the hip joints not in the correct natural position – a seated position.
Ideal Newborn Positioning in a Wrap
Ideal newborn positioning in a wrap aims to mimic how babies naturally position themselves when held in arms. The baby’s legs create an ‘M’ shape with their knees higher than their bottom, often called the frog-leg position. The spine forms a gentle ‘J’ curve, reflecting the newborn’s inherent spinal curvature.
The baby’s head should be turned to the side, resting against the parent’s chest for comfort and security. The wrap supports this positioning, contouring around the baby’s body without altering their organic alignment.
Newborn Positioning in a Ring Sling
Newborn positioning in a ring sling prioritizes natural alignment and comfort. The baby should be snug, with the baby’s spine maintaining its natural curve. Their head rests on the wearer’s chest, placed high enough for easy kissing, yet allows the wearer to look down, provding the most optimal position.
Legs adopt the ‘M’ shape, or the ‘froggy’ position, with the knees higher than the bottom. This provides ample hip support, crucial for early development. The sling should be tightened in such a way to offer sturdy support the pelvic tuck without constraining the baby’s natural position.
Newborn Positioning in a Soft Structured Carrier
In a soft structured carrier, newborn positioning should offer a balance of comfort, support, and freedom of movement. The baby’s legs should form an ‘M’ shape, their knees above their bottom, replicating the natural ‘froggy’ position.
The carrier should support the baby’s natural ‘J’ curved spine and not extend past the bend of the baby’s knees. The carrier panel should reach but not exceed the bottom of the baby’s ears, ensuring good head support without restriction.
International Hip Dysplasia Institute (IHDI)
The International Hip Dysplasia Institute (IHDI) emphasizes the importance of proper baby positioning in carriers to prevent hip dysplasia and dislocation, a condition where the hip joint doesn’t develop properly.
According to the IHDI, the healthiest position for the hips is for the hips to fall or spread (naturally) apart to the side, with the thighs supported and the hips and knees bent. This is often called the “M” position, or “frog-leg” position. This position has been observed in cultures where hip dysplasia is rare and is recognized as contributing to healthy hip development.
Key recommendations from the IHDI for baby carriers include:
1. Thigh Support: Carriers should support the baby’s thighs, not just the crotch area, to encourage the thighs to spread around the wearer’s torso. This helps ensure the forces on the hip joint are minimal.
2. Hip Positioning: The baby’s hips should be allowed to spread apart naturally. The carrier should allow for the baby’s legs to be held in an ‘M’ position with the knees at or higher than the level of the buttocks.
3. Flexibility: The carrier should allow changing positions while the baby is in it, for example, allowing the baby to face towards the wearer or away, as well as change from a vertical to a horizontal position.
The IHDI advises against using carriers that force the baby’s legs to stay together and extended straight for long periods. Carriers that allow for the natural “M” position and have received positive acknowledgment from the IHDI are deemed “hip-healthy.”
Benefits of Babywearing
Undeniably, the practice of babywearing brings an array of benefits, offering a soothing environment for the young ones while providing parents with the freedom to carry on with their daily tasks.
The bonding benefits are significant as baby carriers facilitate skin-to-skin contact, fostering a secure attachment between the child and caregiver. This close contact also supports the baby’s emotional and psychological development.
Baby carriers cater to the developmental advantages as the upright position aids in digestion and helps to alleviate symptoms of reflux. Additionally, the constant motion and balance involved in babywearing can assist in the development of the baby’s vestibular system, which is responsible for balance and spatial orientation.
