Newborn Safe Sleep: A Gentle Swaddling Guide
Few things occupy a new mum's mind quite like sleep — your baby's, and your own. Is she warm enough? Should I swaddle? Is this position safe? Take a breath. You don't need to get everything perfect. A few simple habits go a long way toward helping your newborn sleep safely — and toward giving you a little more peace of mind.
The quick read
- Back to sleep, every nap and every night
- Firm, flat, clear cot — no pillows, duvets or bumpers
- Room-share for the first six months
- Swaddle snug at the chest, loose at the hips
- Stop swaddling at the first sign of rolling
The foundations of safe sleep
Safe-sleep guidance is reassuringly consistent around the world, and it comes down to a handful of principles worth committing to memory. The most important one: always place your baby on their back to sleep, until they can roll both ways on their own.
- Back to sleep, every time. Back-sleeping is the safest position for newborns.
- A clear, flat, firm sleep space. A cot, crib or Moses basket with a firm mattress and fitted sheet — no pillows, duvets, bumpers or soft toys.
- Room-sharing, not bed-sharing. For the first six months, the safest place for baby is their own cot in the same room as you.
- Keep baby smoke-free before and after birth.
- Avoid overheating. Around 16–20°C suits most babies. Light layers beat heavy bedding.
If you use loose blankets, tuck them in firmly no higher than baby's shoulders — though many parents find a well-fitting sleeping bag simpler and safer, because there's nothing to slip over the face. Whatever you choose, breathable natural fibres help regulate temperature through the night.

How to swaddle your newborn
Many newborns settle beautifully when swaddled — the snug wrap mimics the closeness of the womb and soothes the startle reflex that jolts them awake. Swaddling isn't essential, and not every baby loves it. But if yours does, here's how to do it safely.
Step by step
Lay a thin, breathable swaddle blanket flat in a diamond shape and fold the top corner down.
Place baby on their back with shoulders just below the fold.
Gently straighten one arm, bring that side of the blanket across the body, and tuck it under the opposite side.
Fold the bottom up, leaving plenty of room for hips and legs to bend and move freely.
Bring the last side across and tuck it in — firm around the chest, but loose enough to slip two fingers between blanket and chest.
Swaddling safely
Keep in mind
Always place a swaddled baby on their back, never the side or tummy. Leave the hips loose to support healthy hip development. Use light, breathable fabric and check baby isn't too warm. And stop swaddling at the first sign of rolling — often around eight weeks, though it varies. After that, a sleeping bag is the safer choice.
Helping baby settle
Newborn sleep is wonderfully unpredictable, and that's completely normal — tiny tummies mean frequent waking for feeds, day and night. Rather than fighting it, a gentle, repeatable wind-down helps signal that sleep is coming: a dim room, a feed, a fresh nappy, a swaddle or sleeping bag, a calm cuddle. Over time these small cues become a rhythm your baby recognises.
It helps to remember that "good sleep" for a newborn simply means safe, comfortable and fed — not sleeping through the night. That milestone comes later, in its own time.
When to check in with someone
Trust your instincts. If your baby seems unusually difficult to wake, is feeding poorly, has a high temperature, or their breathing worries you at any point, contact your midwife, health visitor or doctor — or seek urgent care if you're concerned. You know your baby, and asking is always the right call.
For many parents, a baby monitor adds a layer of reassurance, letting you rest a little easier while baby sleeps in their own safe space.
