Babywearing

Carrying safely

Babywearing is safe when your child is positioned correctly and you can see them. This page sums up the principles that apply to wraps, ring slings and carriers alike, and links to the sources they are based on.

Why we talk mostly about breathing

The UK charity The Lullaby Trust explains that babywearing accidents usually happen when a baby’s airway becomes blocked: either their chin is on their chest, or their mouth and nose are covered by the parent’s skin or clothing.6 The US CPSC describes the same two risks and adds that a baby in this situation may not be able to cry out.2 That is why almost all the principles below revolve around the face, the chin and the position.

T.I.C.K.S. – five checks

The rule from the UK Sling Consortium of sling manufacturers and retailers is also recommended by The Lullaby Trust and RoSPA.1,5,6

  • 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.

Who needs particular attention

  • Babies under 4 months: they cannot hold up their heads; the CPSC advises extra caution.3
  • Premature babies, low birth weight, breathing difficulties or a cold: talk to your paediatrician.2,5
  • A sleeping baby: in sleep they slip more easily into a curled-up position.

Sleeping in a sling or carrier

The American Academy of Pediatrics does not recommend sitting devices, including wraps and carriers, for routine sleep, especially before four months. If your baby falls asleep, move them to a firm flat surface as soon as it is safe and practical.4 While they sleep on you, keep checking T.I.C.K.S., and don’t sit down with them in a comfy armchair where you might fall asleep too.

Breastfeeding in a sling or carrier

If you breastfeed in a wrap or carrier, after the feed return your baby to an upright position with the head up and the face clear.3

Warmth

A sling or carrier is another layer, and your body is warm. Check your baby’s temperature on the chest or the back of the neck; cold hands and feet are normal. If they are sweaty or hot, take off a layer.7 Never cover your baby’s face with a scarf, a coat hood or a blanket.

Falls and injuries

In its standard for slings, the CPSC requires warnings not only about suffocation but also about the baby falling out.3 In practice:

  • when you need to lean forward, bend at the knees and hold your baby with one hand,
  • put the sling or carrier on and take it off low down, ideally over a bed or near the floor,
  • do nothing with your baby in a sling or carrier that could scald or burn them or risks a fall: cooking at the hob, hot drinks over their head, a bike, a scooter, a ladder,
  • in the car, a sling or carrier never replaces a car seat.

Checking your sling or carrier

Before every use, look at the seams, fabric, straps, buckles and rings. The CPSC also requires this in the instructions for slings.3 Do not use a damaged sling or carrier. With a second-hand one, find out who made it and download the instructions.

The hips

Apart from breathing, it is worth thinking about the hips during long carries. The IHDI recommends a position in which the thighs are supported to the knees and spread, and does not recommend a narrow seat with dangling legs for long carries.8 More in the article Ergonomic carrying and the hips.

The M position in a carrier, with a narrow seat for comparison On the left, a baby seen from behind in the M position: the thighs are spread around the parent’s body, the carrier panel supports them from knee to knee and the knees are slightly higher than the bottom. On the right, a narrow seat: the panel supports only the crotch and the legs hang down. parent’s body Yes: the M position ✓ thighs supported from knee to knee ✓ knees slightly higher than the bottom Less suitable for long carries ✗ a narrow seat supports only the crotch ✗ legs dangle, thighs unsupported
Diagram based on the description by the International Hip Dysplasia Institute (IHDI). The Institute recommends the M position particularly in the first six months, when the hips develop rapidly. It also states that a narrow seat is not a proven cause of hip dysplasia; it is simply a position that does not help hip development during longer carries.

If something happens

If your baby is not breathing, does not respond or has blue lips, take them out of the sling or carrier immediately, lay them on a firm surface and call the ambulance service on 155 or the single emergency number 112. The operator will talk you through the next steps.

Frequently asked questions

What should I do if I am not sure my baby is breathing well?

Stop, loosen the sling or carrier and check that their nose and mouth are clear and there is space under the chin. If your baby does not respond, has bluish lips or is not breathing, call 155 or 112.

Can I cook or ride a bike while wearing a carrier?

Cooking brings a risk of scalds and burns; cycling and similar activities a risk of falls. Do not do these things with your baby in a sling or carrier. If you need to cook, put your baby down somewhere safe.
