Baby wraps
A wrap is a length of fabric that only becomes a carrier once it is on you. That is why, more than with anything else, it matters how it is tied. Here are the differences between the types, the principles that apply to every carry, and the checks to make every time.
What you are actually buying
A wrap is a long strip of fabric. It has no buckles and no ready-sewn seat. You give it the shape of a carrier by tying it. That is its great advantage, because it adapts to a newborn and a toddler alike, and to a short or a tall wearer. But it is also what makes it demanding: a badly tied wrap does not hold the baby as it should.
In the shops you will find two main types and one close relative:
| Stretchy wrap | Woven (non-stretch) wrap | Ring sling | |
|---|---|---|---|
| Fabric | stretchy knit, often cotton with elastane | woven fabric, does not stretch lengthways | woven fabric with two rings |
| How it goes on | can be pre-tied and the baby popped in | always tied with the baby in it | goes over one shoulder, tightened through the rings |
| Who it suits | smaller babies, beginners | from newborn to toddler | short carries, quick to put on |
| On the back | most makers advise against | yes, with a carry that allows it | no, worn on the front or hip |
| Learning | one basic carry | several carries, takes practice | simple to put on, tightening takes practice |
| Warmth | a thicker knit can be warm | depends on the material and thickness | one layer, but it loads one shoulder |
We have a separate guide to the ring sling. If you are still deciding between a wrap and a carrier, the comparison in the article Wrap or carrier will help.
The stretchy wrap: a soft start
You tie a stretchy wrap on yourself before the baby goes in, and then place them inside. For many new parents this is the easiest way into babywearing, because they don’t have to tie with a baby in their arms. The stretch has another side, though: as the child gets heavier, the fabric gives more and the baby can sink lower. That is why makers give weight ranges. Look at them before you buy and compare them with how long you want to use the wrap.
According to most makers, stretchy wraps are not for back carries. If you plan to carry on your back, count on a woven wrap or a carrier whose instructions allow it.
The woven wrap: one piece of fabric for years
A woven wrap does not stretch lengthways, so it holds a heavier child too. There are many carries: front, hip and back. It is always tied with the baby in it and tightened section by section, so that no fabric is left slack. The first weeks call for patience; after that it becomes second nature.
Makers give the length in metres and often as a size number as well. Which length is your “base size” depends on your build and the carry you want to learn. Go by the maker’s chart, not by a one-size-fits-all number from an online forum.
Tying: principles instead of a picture guide
We deliberately do not draw the tying steps. Every carry has its own details and every wrap its own instructions, so a simplified picture could do more harm than good. It is better to practise following the maker’s instructions, first over a bed or with a doll, and ideally once with a babywearing consultant who can see you in person.
The same principles apply to every carry, though:
- Your baby is upright and facing you. The International Hip Dysplasia Institute (IHDI) recommends carrying facing the parent for the first six months.2
- The fabric reaches from knee to knee. The thighs are supported, the knees slightly higher than the bottom. This is the M position.2,3
- You tighten in sections. Pulling on the ends is not enough. Tension the fabric gradually across its whole width so there is no slack anywhere. Slack fabric lets the baby slip down.1
- The back is supported in its natural curve, with tummy and chest snuggled against you.1
- The face is clear. The fabric does not cover the nose or mouth, and there is space under the chin.1
- After every tie and regularly while carrying, run through T.I.C.K.S.
The T.I.C.K.S. check
The UK Sling Consortium of sling manufacturers and retailers summed up safe babywearing in five letters.1 They apply to wraps and carriers alike.
- Tight The wrap or carrier should hold your baby snugly against you. Loose fabric lets the baby slump lower, which can make breathing harder for them and puts strain on your back.
- In view at all times You can see your baby’s face just by glancing down. The fabric must not close over them so that you have to push it aside. In a cradle position the face should point upwards, not into your body.
- Close enough to kiss Your baby’s head is as close to your chin as is comfortable. By tipping your head forward you can kiss the top of their head or forehead.
- Keep chin off the chest Your baby must never be curled so that their chin is pressed onto their chest, as this restricts breathing. There should always be at least a finger’s width of space under the chin.
- Supported back In an upright position the back is supported in its natural shape, with tummy and chest snuggled against you. A check: press your palm gently on their back. The baby should not straighten up or move closer to you.
The M position and the hips
In babywearing people often talk about the “froggy” or M position. The IHDI describes it as the position in which the thighs are spread around your body and supported, with the hips bent so that the knees are slightly higher than the bottom.2 The Institute says this position can support the natural development of the hips, especially during long carries in the first six months. It considers harmful a position with the legs straightened and pressed together, as in tight swaddling.3
In a wrap the M position is easy to achieve, because you spread the fabric exactly from knee to knee. With a tiny newborn, take care not to force the legs apart: it is enough for them to be naturally bent and supported.
A newborn in a wrap
The first months are when the airway is most vulnerable, because the baby cannot yet hold up their head. The US Consumer Product Safety Commission (CPSC) warns of two risks: fabric can cover the nose and mouth, and a curled position with the chin on the chest can restrict the air supply.4 Of the deaths the Commission examined in 2010, most involved babies younger than four months. For premature babies, twins with a low birth weight and babies with breathing difficulties, for example a cold, it advises particular caution and talking to a paediatrician.7
In practice:
- prefer an upright position facing you, with the face in view,
- after a feed in the wrap, return your baby to a head-up position with the face clear,4
- check on them often, not just when you tie the wrap.

When your baby falls asleep in the wrap
Falling asleep in a wrap is common, and many parents love it. The American Academy of Pediatrics, however, does not recommend sitting devices, wraps included, for routine sleep, especially under four months. If your baby falls asleep, move them to a firm flat surface as soon as it is safe and practical.5 While you are carrying them, T.I.C.K.S. applies. And if you are drowsy yourself, take the wrap off. Babywearing while half asleep on the sofa is not a good idea.
When something isn’t right
| What you see | What it usually means | What to try |
|---|---|---|
| Your baby slides lower; their head is too far below your chin | the fabric is not tightened across its whole width | loosen and tighten again gradually, strand by strand |
| The chin is pressing towards the chest | the baby is curled up or too low | lift them higher, check for a finger’s width under the chin |
| The legs dangle, the fabric ends mid-thigh | the seat is not spread from knee to knee | spread the seat again under the knees |
| One shoulder hurts | the fabric is not spread out, or it is a one-shouldered carry | spread the fabric over the shoulder, alternate sides |
| Your baby is hot and sweaty | too many layers; the wrap itself is warm | take off a layer of clothing; see babywearing in summer |
Caring for and checking your wrap
Before every use, look over the seams and the fabric. If it is torn, has holes or is pulled anywhere, do not use the wrap. Wash it according to the label; some materials change their stretch or shrink after washing. For slings, the CPSC specifically reminds you to check the rings, buckles and other parts too.4
Check a second-hand wrap even more thoroughly before use, and find out who made it so you can look up the instructions.

Frequently asked questions
From what age can I use a wrap?
Many wraps are designed by their makers for use from birth, provided the baby meets the minimum weight given in the instructions. For premature babies, babies with a low birth weight or with breathing difficulties, talk to your paediatrician first; the US CPSC advises extra caution with them.
Is a stretchy or a woven wrap better?
A stretchy wrap can be pre-tied and the baby popped in, which is pleasant for a beginner, but it gives more as the baby gets heavier. A woven wrap does not stretch, holds a heavier child and allows more carries, but it needs to be tightened more precisely. If you plan to carry for longer than a few months, a woven wrap tends to be more versatile.
Can my baby sleep in a wrap?
Babies often fall asleep in a wrap. The American Academy of Pediatrics (AAP) does not recommend wraps or other sitting devices for routine sleep, especially under 4 months. If your baby falls asleep, move them to a firm flat surface as soon as it is safe and practical. While you are carrying them, keep checking the T.I.C.K.S. rule.
