Size Guide

Butterfly Cardi

The Butterfly Cardi is designed to be a firm fit, to mimic the enclosed feel of a swaddle. The firmness can also be adjusted using the press-studs according to how strong your child's startle reflex is. Choose the tighter fit for a strong reflex, and the looser fit for older babies who have lost their startle reflex.

Best For


Not all babies enjoy having their arms swaddled in. That's where the Butterfly Cardi comes in. This innovative design allows you to keep your baby's arms close to their face, with the hands-up option. Additionally, it can be used as a transition aid for when your baby is ready to move into arms-free sleeping. You can simply wear it over your baby's swaddle to help them adjust to the change.

Hands-up sleeping
Some newborns find comfort sleeping with their hands up near their face. If your baby falls into this category, simply wear the Cocoon Swaddle Sack (sold separately) with arms-out, pop the Butterfly Cardi on over the top, and contain the hands in the butterfly wing pockets in a position near the face. This is safe from birth, when using our 0-3 month size. If your newborn baby changes sleep style regularly, the Cocoon Swaddle Sack paired with the Butterfly Cardi gives you three sleep options to switch between (arms-in, arms-out and hands-up).

Transitioning out of a swaddle
If your baby has been sleeping swaddled with their arms in or up, and begins to show signs of rolling, it is time to transition them to arms-out sleeping for their safety. The Butterfly Cardi is innovatively designed to be a transition aid worn over your baby’s swaddle or sleeping sack, to help them transition to arms-out with minimal sleep interruptions and maximum sleep comfort. The 0.2 TOG rating makes it a light layer suitable for use over any sleeping sack in any room temperature.

The Butterfly Cardi features unique arm pockets to create a sense of containment, the feeling you baby will be used to from swaddling. By gently releasing one arm out of the swaddle at a time and into the pocket, you will be easing your baby to sleep fully arms-out over a period of 10 days, helping them get used to the new sensation as you go. With their arms inside the pocket, your baby will also have access to their hands for self-soothing. For babies who may still have a strong startle reflex, the press studs can be adjusted to make a firmer fit around your baby's torso. View full How-to-use instructions here.

Safe for sleep
No matter which way you choose to use the Butterfly Cardi, the super stretch in all directions will ensure your baby remains comfortable and allow for full chest expansion when breathing. The position of the Butterfly Cardi on the body will not interrupt the natural sleeping position for healthy hip joint development.

The Butterfly Cardi is made with our signature premium GOTS certified organic jersey cotton. Natural fibres are better for sleeping for the simple reason they are breathable, and help your little one regulate their temperature overnight. Our certified organic fibres are also skin-friendly and sensitive on eczema and dry skin conditions. All ergoPouch fabrics are dyed with non-toxic water based dyes.

How To Use

For hands-up sleeping
1. Dress your baby in a Cocoon Swaddle Bag with the arm studs open, or appropriately sized arms-out sleeping bag.
2. Lay your baby on top of the Butterfly Cardi, and contain their hands in the foldover arm pockets.
3. Do up the studs according to the strength of their startle reflex (tighter, if strong reflex. Looser, if weak reflex).
4. Their hands should be up near their face when lying on their back.
5. To transition to arms-out sleeping once showing signs of rolling, release arms fully from the foldover pockets (see below).

Always put baby down to sleep on their back, in a safe-sleep environment.

For transitioning out of a swaddle
We recommend transitioning over a 10 day period. This should commence when your baby first shows signs of wanting to roll (not after they start rolling) for their safety.

DAY 1 - 3
Dress your baby in the Butterfly Cardi over their sleeping bag or Cocoon Swaddle Bag with their arms contained within the fold-over arm pockets for all their sleeps (day & night).

Use the press studs to adjust the firmness of the Cardi around the torso. If your baby has a strong startle reflex, start with a tight fit. If your baby has a low startle reflex, you can start with the looser fit.

DAY 4 - 7
After your little one is familiar with their new sleepwear addition, you can now take one arm out of the fold-over pocket for all their sleeps.

DAY 8 - 10
In this next stage, you can take their remaining arm out of the other pocket for all their sleeps. On the final day, remove the Cardi altogether. Your baby is now sleeping, arms-out. Hooray!
