Product details
Meet the 3-IN-1 FX Swaddle. Designed in Australia, it comes built-in with 3-IN-1 arm positions (Arms-In, Arms-Free, and Hands-Out) to accommodate your baby’s changing needs, preferences, and development stage.
The FX (Fetal Flex) Swaddle is the only swaddle that emulates the natural essence of the womb environment by swaddling your baby in the naturally preferred Arms-Free (Fetal Flex) position, while still suppressing the Startle (Moro) reflex.
Similar to the womb environment, the FX Swaddle provides your baby optimum comfort and feeling of security, promotes better development and self-soothing, while minimising spontaneous awakenings – helping your baby sleep better and longer – providing a gentler way to transition your baby from 'womb to world', and from 'swaddle to sleeping bag'.
Features & Benefits Summary
- Swaddles your baby in the naturally soothing fetal position – which provides optimum comfort and reassurance, reduces overstimulation, making your baby feel calm, cosy and safe.
- Patent pending design emulates the natural essence of the womb environment by swaddling your baby in the naturally preferred ‘arms free’ (fetal-arm) position, while still suppressing the Startle (Moro) reflex.
- Arms free (fetal-arm) position + suppressing startle reflex = better development, more self-soothing and less spontaneous awakenings = more sleep for baby and easier transition out of swaddle = more sleep for mum and dad.
- Patent pending built-in 3-in-1 arm positions (Arms-in, Arms-free, or Hands-free), provides a gentler way to transition your baby from 'womb to world', and from 'swaddle to sleeping bag'.
- The narrowed/tapered waistline design provides gentle pressure on baby’s belly, which can help ease colic and eliminate gas related issues.
- Hip-healthy bell shaped design allows baby’s hips and legs to flex and move naturally, which helps the hips develop normally.
- The design of the FX swaddle and the stretch cotton fabric allows proper chest wall expansion, allowing baby to breathe freely and minimising the risks associated with tight chest wrapping.
- Made with stretchy but snug 95% cotton 5% spandex for optimum breathability, comfort and to reduce the risk of overheating.
- Australian safety standard approved. The FX Swaddle conforms to the Australian safety standard AS/NZS 1249:2014
- Escape proof zip-up design prevents baby escaping from the swaddle. Safer alternative to velcro or traditional swaddles which can unravel and cover your child’s face.
- Two-way zipper for easy nappy changes.
- Super easy to use, simply place baby in the swaddle and zip up. No wrapping required!
- Easy cleaning/care.
Sizing Guide
Babies grow at different rates, and weight and height can vary significantly between babies of same age. Therefore, we recommend choosing the swaddle size according to your baby’s Weight or Height, whichever is greater of the two, instead of baby’s age. Please feel free to contact us if you require any assistance.
STEP 1 – Base Size
Select a base size below according to your baby’s current WEIGHT or HEIGHT, whichever is greater of the two.

STEP 2 – Final Size
Upsize to next size up if ANY of the below applies to your situation, otherwise keep to the base size from STEP 1.
- If your baby’s current weight/height falls in the middle or higher end of the base size weight/height ranges.
- If you are intending to swaddle your baby ARMS-IN ‘with hands placed over chest’, as more chest room is required for this arm position. However, if you are intending to swaddle your baby ARMS-IN ‘with hands by the side of the body’ (our recommended ARMS-IN position), then keep to the base size unless any of the other conditions applies to your situation.
- If you are intending to dress baby underneath the swaddle in thick/multiple layers, for example during cooler months.
- If your baby prefers to sleep with arms up high or prefers a more relaxed fit.
Side note: Young babies can go through growth spurts at any time. To avoid unexpected delays in receiving your swaddle, we recommend you choose the Express Shipping option during checkout. For shipping info please visit https://sleepycompany.com/shipping-returns-warranty
How many swaddles do I need?
We recommend purchasing at least two FX swaddles per size. Consider getting an extra spare for added convenience, as babies can be messy with leaking nappies and spitting up milk.
One to wash, one to wear, and one to spare!
Dressing Guide
Light Weight
Light Weight FX swaddle is made from a single layer of cool stretchy cotton fabric (approx 0.2 Tog). It is suitable for Summer use with light clothing or just a nappy, and Autumn/Spring use with warmer clothing underneath.You can dress baby underneath the swaddle as appropriate for the nursery temperature:
- In cooler temperatures, dress baby in warmer layers underneath the swaddle.
- In warmer temperatures, dress baby in lighter layers underneath the swaddle.
- During hot summer days it may be sufficient to dress baby in just the swaddle and nappy. Here are some additional suggestions:
- Undo the bottom zipper so that swaddle is partially open from below chest to feet. This will allow more air circulation and keep baby cooler.
- Keep nursery temp between 18 and 22 degrees if possible.
- Consider using a fan in baby’s room for better air circulation.

- Undo the bottom zipper so that swaddle is partially open from below chest to feet. This will allow more air circulation and keep baby cooler.

General Dressing Guide
As a good starting point, we recommend that you dress your baby as you would dress yourself for the room temperature; comfortably warm, neither too hot nor too cold. Feel your baby's chest, tummy, or back regularly to check his/her temperature. It should feel comfortably warm, not too hot or cool to your touch. You can then add or remove layers as needed.
You needn't worry too much if your baby’s hands and feet feel cool. This is normal for babies due to their immature circulatory systems causing a delay in blood movement to the extremities.
Please note, all babies are all different; additionally, other factors such as humidity in your region, whether there is heating in the house, and your baby's health (whether your baby has a cold or infection or another special need) can determine how you should dress your baby. If your baby is sweating or has a red face, remove some clothing. This may be necessary if your baby is unwell, in which case you should seek medical attention.
- This dressing guide is for general guidance only as all babies are different.
Safe Swaddling Tips
- Always sleep baby on the back, not on the tummy or side.
- Do not use swaddle if head can pass through the neck-hole or if neck-hole is too tight.
- If your baby is attempting to roll from back to tummy during sleep, discontinue swaddling (use our 365 Sleep Bag V3, or the X-TEND Sleepsuit instead), or swaddle only with baby’s hands completely free/out. Ensure baby’s hands are uncovered, and baby is able to move arms freely to push his/her face off the bedding surface if he/she happens to roll from back to tummy.
- Always follow safe sleep recommendations from children's health care professionals.
