Trading Standards supports the safe use of infant slings. However, there are dangers associated with incorrect use of some slings, and one type in particular is unsafe.

What are the dangers?

Babies have suffocated while being carried in slings. They are at risk if placed incorrectly as they are not able to move out of dangerous positions which block their airways. Babies who are low birth weight, born prematurely, or who have breathing issues such as a cold appear to be at most risk.

Parents and carers should take extreme care if using slings and pouches to carry babies under 4 months old / 4 kg.

Two positions present significant danger:

  • a curved back with the chin resting on the chest
  • having the face pressed against the fabric of the sling or the wearer’s body

As well as the risk of suffocating, babies are also at risk of receiving low levels of oxygen because of the position they are in, or falling out and suffering injuries.

Don’t let anything block the baby’s face – like the sling or the wearer’s body. Small babies cannot turn their heads to get fresh air.

Don’t let the baby lie in a curved position with their chin resting on their chest. Any pressure on the chin can push the tongue back and close the airway. Babies need to lie with a straight back so that the tummy muscles can pump old air out of the lungs and new air in, and their head up to ensure a clear airway.

Dangerous baby slings

Never use a bag sling. A bag sling is one shaped like a bag with a narrow strap – see the diagram. The baby cannot be placed in a safe position and can suffocate. One brand (Infantino) has been recalled following three deaths of babies in the US, but any sling of this design is unsafe.

Never use products that allow the baby to lie with a curved spine – these are described as ‘womb-like’, or a ‘cocoon’, or placing the baby in a ‘foetal position’. These place the baby in a dangerous position with a curved back which folds the windpipe and blocks the airway. A foetus doesn’t need a straight back to breathe – a baby does.

When not to use a sling

Don’t do anything while wearing a sling that you wouldn’t do with baby in your arms.

If you need to carry out any activity involving water, machinery, heat, or excessive movement – put baby to sleep safely in a cot.

Don’t use a sling when you are smoking or under the influence of medication or alcohol.

Certain slings aren’t suitable for small or premature babies.

Carry baby in an upright position if ill, even if it’s just a cold.

Buying a sling

Slings are made from fabric and are designed to help with carrying babies by easing the pressure on your arms or back. There are many different designs and some are safer than others.

Before you buy, do some research, and try to contact a babywearing group for advice. 

  • Take your baby with you when you buy a sling to ensure that the product you buy is a safe fit for you and the baby.
  • Ask the shop assistant for a demonstration of how to use the sling correctly. If they aren’t sure – buy elsewhere.
  • Ensure any sling you buy comes with detailed instructions for use. Make sure you follow them and get someone to help until you are familiar with how to use it.
  • Choose products that stop a baby from moving into a position where they can suffocate.
  • Choose products that are appropriate for your baby’s stage of development. 

Wearing a sling

A baby held in the arms is naturally in a safe position – the head is supported, the back is straight and the airways open. A sling should hold the baby in the same way.

Woman holding baby

In an instinctual in-arms cradle carry the infant is carried in a slightly inclined position, with the bottom slightly lower than the back, which straightens the back yet still allows for a slight, gentle curve.

Check that baby is in the right position in the sling by placing your arms around him as you would to hold him in-arms. If this lifts or repositions baby, it means the baby was in the wrong position and the sling needs to be adjusted.

The neck and the base of the infant’s head are supported by the parent’s forearm yet the upper portion of baby’s head is slightly dropped off the parent’s forearm. This carrying technique opens the infant’s airway and provides space for lung expansion.

Regularly check that

  • the baby’s face is clear.
  • the baby’s spine is straight.

Immediately reposition or remove the baby from the sling immediately if you observe these signs: 

  • face covered or chin tucked in
  • head turned to the side
  • curled into a ‘C’ position
  • grunting, wheezing, whistling breaths
  • laboured or rapid breathing
  • a dusky or ‘blue’ tinge on the baby’s skin
  • ‘fussiness’, restlessness or squirming.
