Swaddling: How to swaddle a baby for safe sleep

Newborn Sleep Infant Sleep Product Information

Hi! If you’re new here, welcome. Perhaps you're expecting your first mini, you’re adding to your family and need a quick refresher, or your baby is about to have a baby, and you want to relearn to lend a hand – congratulations to all of you!

Whatever the reason, we understand how overwhelming it can be whenever a mini is on the way. Our job is to guide you through the process of swaddling and answer all your burning questions. As many of us are mothers ourselves, we've been where you are, and we want to ensure you feel supported as you enter into this journey of newborn sleep.

What is swaddling and why do it?

Swaddling is an ancient practice of wrapping your baby in a cocoon to help them feel safe and secure. We swaddle our babies to avoid the sudden flailing of their arms and head that swiftly snaps them awake, undoing all that hard work it took to get them to sleep. That flailing movement is known as the Moro, or startle reflex. It is a jerk in their bodies that can occur every 20 minutes in some babies. It is completely normal and begins in the first trimester in utero. A loud noise, a sudden bright light, movement or even a parent laughing can trigger the reflex. Swaddling calms this jerking movement while keeping your mini comfortable and content. 

The transition from the cozy confines of the womb to life outside can be anything but easy for newborns who are used to mom's comforting warmth and movement. The first few months are commonly referred to as the 'fourth trimester', and your newborn will probably sleep for around 16 hours a day as their body grows rapidly, their brain develops, and they learn a circadian rhythm. A swaddle can help your baby adjust to the outside world by providing security and familiarity. It can help to settle your little one if they become overstimulated by their surroundings. 


Is swaddling for every baby? 

All babies are wonderfully different. Some like to sleep in an environment that mimics the close confines of the womb, while some like the freedom of sleeping with their arms out, and some don't like being swaddled at all.  For these babies, we suggest trying using our Cocoon Swaddle Sack as a sleep sack with the arm studs undone. Once they are three months of age, you can try one of our infant sleep sacks, which provide a roomier fit for babies who don’t like being confined. 

Regardless of which pouch you choose, a safe sleeping environment is paramount:

  • For sleep, always place your baby on their back at the end of the crib or bassinet;
  • If you choose a Cocoon Swaddle Sack or sleep sack, you won't need any blankets for extra warmth;
  • Ensure the sack is fitted well around the neck and armholes but not too tight;
  • Their sleeping surface should always be firm and flat; 
  • There should be nothing else inside their crib. That includes blankets, crib bumpers, pillows, toys or mobiles hanging above them that could fall or be in reach. An exception is the Baby Tuck Sheet, which is designed for babies who are not rolling. When the right size is used, the sheet cannot be pulled over a baby's head, become untucked from the mattress or be classified as loose bedding, in any way; 
  • Sleep baby with face and head uncovered, no beanie or bows and free from a smoking environment; 
  • The crib or bassinet should have a safe mattress and base.

Traditional Swaddle Wraps vs Pouch Swaddles

There are two types of swaddles: a traditional swaddle wrap or a pouch (also known as a swaddle sack). Both will ensure your baby feels secure and can help with settling to sleep. Please be wary of wraps and swaddles that don't allow for full and uninhibited chest expansion. Those little ribs are still very soft and bendy, and an overly enthusiastic wrap has the potential to be too firm across the chest. 

While the idea of a swaddle is to contain the startle reflex to keep baby from waking, babies also need some arm movement to promote healthy development and shoulder joints. A swaddle shouldn't be so tight that it pins your baby's arms in one place. Be sure to allow some natural arm movement. Look for a swaddle with stretch, such as the Cocoon Swaddle Sack, to allow for this.


Traditional Swaddle Wraps:

  • Typically, these are muslin, cotton wrap or a thin blanket;
  • This type of wrapping is designed to swaddle your baby like a burrito;
  • Newborn babies are wrapped with their arms over their chests; 
  • Generally, this style will be shown in hospital after you have given birth;
  • This method can be hard to master, and you will often find your mini has escaped their wrap, leading to more wake-ups during the night.


Baby transitioning from arms-in to arms-out sleeping, wearing the ergoPouch Cocoon Swaddle Sack

All about our Cocoon Swaddle 

Our Cocoon Swaddle Sack is a zip-up, no-fuss swaddle in stretchy organic cotton. It’s hip-friendly, diaper-change friendly, and it transforms into a sleep sack. It is designed to be both easy to use and difficult to escape from. We know babies and children sleep better in natural fibers for the simple reason that they improve breathability and keep your little one's body at an even temperature, resulting in a safe and content sleep for your mini. 

All ergoPouch sleepwear is TOG-rated and made from breathable, natural fibers such as soft organic cotton with 5% elastane, which allows for stretch in all directions across the chest. This blend creates a cozy and comfortable swaddle in which to sleep your baby. The TOG-rating means that you can easily match your baby’s night-time outfit for the temperature of the room, which takes the guesswork out of bedtime and removes the need for a blanket. Learn more about TOG ratings.

The Cocoon Swaddle Sack has received an acknowledgement from The International Hip Dysplasia Institute for being a "hip-healthy" product. The ergonomic bell-shaped design provides enough room for hip mobility and allows babies to move their legs comfortably and adopt 'frog-leg' position. They’re available in sizing 0000, 0–3 months, 3–6 months and 6–12 months. 


A note on organic cotton vs. polyester 

Sleepwear that is filled with synthetic fibers, such as polyester, will make your child overheat and sweat, which may wake them frequently throughout the night. Natural fibers such as cotton are the best choice for sleepwear as they allow children's sensitive skin to breathe, reducing the chance of overheating and encouraging a longer sleep — hooray! Synthetic fibers and the irritation caused by rubbing on sweaty skin can also cause eczema flare-ups. For those babes who are prone to eczema, breathable and organic fabrics will go a long way to keeping your mini's skin smooth and soft.

What is a TOG? 

TOG stands for Thermal Overall Grade and is a unit of measurement for insulation and warmth of sleepwear and bedding. We have three TOG ratings across our swaddles – 0.2, 1.0 and 2.5 TOG, and a fourth (3.5 TOG) in our other sleeping bags, which cover your baby from 57°F to 72°F+. Put simply, the higher the TOG, the warmer the product. The lower the TOG, the cooler the product.

Examples of baby sleeping bags with different TOG rates: 0.2 TOG for summer, 1.0 TOG and 2.5 TOG for winter

Many parents worry if their baby is warm enough and often pile on blankets or synthetic fibers, which can be unsafe during sleep. Using TOG-rated products designed for safe sleep is a safer and more practical alternative.

The ergoPouch TOG rated system: 

  • 0.2 and 0.3 TOG = 72 degrees Fº+
  • 1.0 TOG = 70 degrees Fº – 75 degrees Fº
  • 2.5 TOG = 63 degrees Fº – 70 degrees Fº 
  • 3.5 TOG = 57 degrees Fº – 66 degrees Fº  - From 3 months only

Fun Facts about the Cocoon Swaddle Sack

  • They're easy for the middle of the night poo explosions, unzip the 2-way, zipper pull their little legs out and get changing. You can keep their little arms wrapped inside the Swaddle. They won't even know they've made a big mess in the middle of the night. 
  • If baby is too warm, undo the lower portion of the two-way zip on your pouch to let air flow through in the early evening. Zip them up later in the evening before you go to bed to keep warmth in overnight.
  • A Cocoon Swaddle Sack can become a positive association very quickly. Your baby will start to recognize the smell and sight of their pouch and associate this with restful sleep. If you consistently use the Cocoon Swaddle Sack as part of your settling ritual, your baby will then be able to transfer this association while out and about. They will quickly understand if they are in their Cocoon Swaddle Sack, it's time to sleep. 


Transition to arms out 

You've made it through the first few months, hooray! And then comes baby's first significant milestone – rolling – and undoes all that hard work! Many parents are apprehensive about unswaddling their baby for fear of what it will do for settling and sleep. What those parents may not know is that once a baby shows signs of rolling it is no longer safe to swaddle them, and the transition to arms-out sleeping must begin.

Read our comprehensive guide on transitioning baby from swaddle to arms-out sleeping.


We know that sleep is a journey, not a destination. As your baby grows and develops, their routines, needs and sleep habits change. So, we don't promise easy fixes or magical solutions, but we do promise that we're here to support you through your family's sleep journey.
