What is a Cocoon Swaddle Bag?

The 3.5 TOG Cocoon Swaddle Bag is a zip-up, TOG-rated swaddle designed to make safe sleep simple for new parents from birth. The multi-functional Cocoon has you covered no matter your newborn's preference for sleep; arms-in, arms-out, or hands up* *Hands-up mode possible when using in conjunction with a Butterfly Cardi, sold separately.

Materials & Care

Materials

Outer: 95% Organic Cotton / 5% Elastane
Inner: 95% Bamboo Viscose / 5% Elastane
Filling: 100% Organic Cotton

The Cocoon Swaddle Bag is made from and filled with Global Organic Textile Standard (GOTS) certified organic cotton that is non-toxic and gentle on sensitive and/or irritable skin. All ergoPouch fabrics are dyed with non-toxic water based dyes. The Cocoon Swaddle Bag is reviewed by the Eczema Association of Australasia (EAA) as a skin-friendly product.


Care

How to wash and dry your Cocoon Swaddle Bag

  • Gentle cold machine wash in mild detergent
  • Do not soak or bleach
  • Tumble dry low
  • Warm iron if required
  • Do not dry clean

When cared for properly, this product will last several years and can be used for more than one baby. Our TOGs don't lose their warmth ratings over time, but a gentle fluff up in the dryer on a low setting helps maintain the fibre's loft, allowing air to circulate more effectively.

More to Love

Two Way Zip

The two way zip makes swaddling easy; simply zip baby in. A lifesaver for easy dressing and even easier overnight nappy changes to get your mini back to sleep, faster.

Super Stretchy

The firm-yet-stretchy fit comforts and soothes baby, whilst still allowing for natural movement, full chest expansion and healthy joint development.

TOG-rated for warmth

TOG stands for Thermal Overall Grade, and is a measure of warmth in fabric. Choose a TOG suitable to the room temperature of baby's sleep environment, and be assured that your baby is safe, warm and secure in our non-toxic, organic and natural fibres.

What is a swaddle, and why use one?

In the early days after birth, a newborn will experience a startle reflex. This reflex causes the hands and body to jerk during sleep, and this action can often wake or unsettle them. Using a swaddle can help contain this sudden movement and prevent waking. Swaddling can also soothe and settle them to sleep by providing a feeling of containment, similar to their experience in the confined space of a womb. Our Cocoon Swaddle Bag also has the following benefits:

  • Keeping baby’s body warm in the early stages when their ability to regulate body temperature is still developing.
  • A hug! A baby would love to spend the whole night bundled up in their parent’s warm arms so swaddles help create that sensation of being hugged.
  • Can help a baby focus on feeding by keeping their arms and legs out of the way.
  • Prevents baby from scratching themselves with their nails.
  • Swaddling = a longer sleep for everyone!

What TOG rating do I choose for the Cocoon Swaddle Bag?

You would choose a suitable TOG based on the temperature of the room your baby is sleeping in.

To take the guesswork out of dressing your little one for sleep, please check our room temperature and What to Wear Guide to help you decide the right TOG rating, and how to layer underneath

What size Cocoon Swaddle Bag do I choose?

It is important that you choose the right size for your baby’s weight. Please do not be tempted to upsize, to get more wear out of the swaddle. You can follow our Size Guideto see what size will be best suited for your baby. If you are pregnant, we suggested buying one Newborn size, and one 0-3 months size.

How many swaddles do I need?

We recommend that you start with at least two Cocoon Swaddle Bags, one to wear and one in the wash. A baby can be a messy creature with leaking nappies and spitting up milk! If you are tacking different room temperatures in the day, opt for two in each TOG rating

How do I use the Cocoon Swaddle Bag?

  1. Open the Cocoon and lay on a low, flat surface
  2. Lay your baby on top, and zip up from the bottom. You can choose to have their arms down at their side, or across their chest when you zip up based on sleeping preference.
  3. To change their nappy, zip up from the bottom to release their legs and lower torso. You do not need to fully upzip the Cocoon, or release their arms, for this.
  4. To transition to arms-out sleeping, open the arm-poppers at the shoulders before dressing your child in the Cocoon.
  5. Sleep your child in their Cocoon Swaddle Bag with their feet touching the end of their bassinet or cot.

Can my baby sleep with their arms up in a Cocoon Swaddle Bag?

Our swaddles are made from a stretchy fabric to allow for natural arm movement, but a baby won't be able to get their arms all the way up to the sides of their head in an ergoPouch Cocoon Swaddle Bag when in the 'arms-in' position. If your newborn baby prefers to sleep arms-out or hands-up by their face (i.e. not swaddled) – that’s OK! Simply open the arm poppers of the Cocoon Swaddle Bag to let their arms out. You can keep them like this, or dress them in a Butterfly Cardi over the top of their Cocoon Swaddle Bag if they still have a strong startle reflext, but like their hands positioned near their face during sleep. Not matter which you choose to have their arms, the Cocoon Swaddle Bag is still the warmest, safest solution for non-swaddled newborn babies during sleep.

How do I swaddle safely?

The neck must be fitted to avoid a baby’s head slipping down into the swaddle. To check for correct fit, you should be able to fit two fingers in the neck hole when being worn.
Swaddles should be firm across the torso whilst still allow for full chest expansion when breathing, as those little ribs are still very soft and bendy so an overly enthusiastic swaddle has the potential to be too tight across the chest.
The swaddle should be loose around the hips and legs, allowing them to flop outwards in a frog-like position while the baby sleeps. Tight swaddling across the hips that hold the legs together is thought to contribute to and increase risk of developmental dysplasia of the hip (DDH).
Babies don’t regulate their body heat very well and rely on their coverings to keep them warm but not hot. Do not overdress a baby underneath their swaddle and never cover their head at sleep time (e.g. with a hat or beanie). Chose a TOG rated swaddle such as our Cocoon Swaddle Bag to avoid using loose blankets in baby's sleep space, as they are bulky and have the potential to overheat a baby or cause suffocation. Remove any other suffocation hazards such as toys or cot bumpers from the sleep space.
Swaddling needs to be secure, without any chance of fabric draping over the baby’s face.

    Happy sleepy baby

    Our 9 weeks old just loves her sleepy suit. We live in face Middle East and with it being so warm outside, indoors can often be too chilly with the AC, but this sleepy suit lets you ensure baby is snug and perfectly adjusted for the conditions. Absolutely love it.

    Using for a newborn

    Baby is on the stronger side and showing signs of being able to get up on her side at 2 weeks so decided to do arms free sack like this one. Did use with arms buttoned for a few days but honestly the sack is so cozy that I think she feels swaddled even though her arms are out. It’s warm and thick and really well made. I will be buying the next size up when it’s time!
