Is it safe to breastfeed in a sling or carrier?

The verdict

Feeding in a sling is possible for some parents and some babies, but the version sold in videos, where you walk around the shops with a baby latched and both hands free, is the version safety bodies advise against.

The Lullaby Trust is direct: hands-free breastfeeding or bottle feeding, where the wearer moves around and does other jobs while the baby is feeding, is unsafe. This is especially true for babies under four months old, and applies to babies born prematurely or those with a health condition. Its practical advice is blunt: if the baby needs to feed, take them out of the sling.

If you do feed in a sling, treat it as a stationary, hands-on activity that ends with the baby being repositioned upright, not as a way to multitask.

Why the airway is the whole issue

Slings are not dangerous because of the fabric. They are dangerous when a baby's airway closes without anyone noticing.

The Lullaby Trust states that the risk of these accidents happening appears to be greatest when a baby's airway is blocked, either because their chin is resting on their chest or their mouth and nose are covered by the parent's skin or clothes.

Two facts about small babies make this worse than it sounds. They breathe mainly through their noses in the early months, so a nose pressed into fabric or breast tissue is a serious obstruction, not a minor one. And they have limited head control, so a chin that drops onto the chest often stays there. A baby in that position does not thrash or shout. They go quiet, which is precisely why a parent absorbed in something else does not notice.

Feeding makes it worse in a specific way. To latch, the baby is usually lowered in the carrier and turned inwards, which is exactly the position most likely to close the airway if it is not corrected afterwards. The most dangerous moment is not the feed. It is the twenty minutes afterwards when a sleeping baby is left low and curled.

TICKS, and what it means during a feed

The Lullaby Trust promotes the TICKS checklist for sling safety: Tight, In view at all times, Close enough to kiss, Keep chin off the chest, Supported back. The HSE in Ireland and RoSPA give the same checklist.

Read those five during a feed rather than in the abstract. Tight means the baby is held against you rather than hanging in a loose pouch. In view at all times means you can see their face without moving fabric. Close enough to kiss means their head is at chest height, not down at your waist. Keep chin off the chest means at least a finger's width under the chin, which is the item feeding most often breaks. Supported back means the sling holds them in their natural position rather than letting them slump into a C-shape.

The rule that ends the feed

Bring the baby back up. A baby who falls asleep feeding in a sling should be returned to a safe upright position, high on your chest, face visible, chin off chest, before you do anything else. This is the step people skip because the baby has finally settled, and it is the step that matters most.

Who should not do this at all

The Lullaby Trust's cautions are worth taking literally. Do not feed hands-free in a sling if your baby is under four months old, was born prematurely, is small, has a cold or blocked nose, or has any medical condition affecting breathing or muscle tone.

Add your own state to that list. If you are exhausted enough that you might doze standing or sitting, do not have a baby latched in a sling. The same reasoning that makes sofas dangerous applies to any position where a sleeping adult cannot monitor a baby's airway.

Bag-style slings that hold a baby lying flat and low, curled with the chin on the chest, have been associated with deaths and are the design safety bodies warn about most strongly. RoSPA and the Lullaby Trust both advise choosing a carrier that holds a baby upright, high and close, with the head and neck supported.

How to do it more safely, if you do

Sit or stand still. Do not walk, cook, carry hot drinks, use stairs or drive. Nobody should be in a sling in a moving vehicle at all, which our page on feeding in a car covers.

Keep one hand supporting the baby's head and neck throughout, and use the other to hold your breast away from their nose if needed.

Loosen the sling only as much as you need to lower the baby, and re-tighten as soon as the feed ends.

Keep the face uncovered at all times. Do not use the sling's hood or a muslin over the baby's head to feed discreetly. Covering the face is the single most dangerous shortcut in this area.

Practise first with an experienced sling librarian or peer supporter. Many areas have sling libraries where you can be shown, in person, with your own carrier and your own baby.

Where guidance differs

The safety advice is consistent across the UK and Ireland.

The UK, through the Lullaby Trust, states that hands-free feeding in a sling is unsafe, especially under four months, and that a baby who needs to feed should be taken out of the sling. RoSPA promotes the same TICKS checklist and warns about carriers that curl a baby's chin onto their chest.

Ireland, through the HSE, gives the same sling safety advice, with the same emphasis on keeping the baby's face visible and the chin off the chest.

Australia, through the Australian Breastfeeding Association, supports carrying and feeding in slings for parents who want to, with the same airway conditions attached.

No safety body has changed its position on hands-free feeding, and none endorses it for young babies. Where you will find disagreement is between official guidance and carrier marketing.
