It's 3 a.m. Your baby is fed, changed, drowsy, and then one small arm startles upward and they're wide awake again. You rock, you shush, you wonder how anyone does this.
Then a midwife, or your mother, or a friend, shows you how to swaddle. You wrap your baby snugly, and within minutes they're asleep. It can feel like a small miracle.
Swaddling is one of the oldest ways to soothe a newborn. Done well, it helps babies feel secure and settle more easily. Here's how to swaddle a newborn safely, and what to look for in the fabric.
Why swaddling helps newborns settle
For nine months your baby lived somewhere warm, snug and muffled. The outside world is big by comparison. Swaddling recreates some of that closeness. It also dampens the startle reflex (the Moro reflex), which can make tiny arms fly up and wake a sleeping baby.
Many parents find a swaddled newborn:
- Settles into sleep more easily
- Stays asleep longer between feeds
- Seems calmer during the fussy evening hours
Is swaddling safe?
Yes, when it's done correctly. Keep these safety rules in mind:
- Always place a swaddled baby on their back to sleep. Never on their tummy or side.
- Keep the hips loose. Your baby's legs should be able to bend up and out at the hips. A swaddle that is tight around the legs can harm hip development.
- Snug at the chest, not tight. You should be able to slide two or three fingers between the swaddle and your baby's chest.
- Avoid overheating. Use a thin, breathable fabric, keep the room at a comfortable temperature (around 16–20°C), and never cover your baby's head.
- Stop when your baby starts to roll.
- If you're unsure, ask your midwife, health visitor or consultatiebureau for a demonstration.
How to swaddle a newborn in 5 steps
- Make a diamond. Lay the swaddle flat as a diamond. Fold the top corner down about 15 cm.
- Position your baby. Place your baby on their back, shoulders just below the fold.
- Wrap the first side. Hold your baby's right arm gently straight at their side. Bring the right-hand side of the fabric across the body and tuck it under the left side of the back.
- Fold up the bottom, loosely. Bring the bottom corner up over the feet, leaving plenty of room for the legs to bend and move. Tuck it lightly at the shoulder.
- Wrap the second side. Hold the left arm at their side, bring the left-hand fabric across the body and tuck it under the back.
Check: snug around the chest, loose at the hips, face and head fully uncovered.
When to stop swaddling
Stop swaddling as soon as your baby shows signs of trying to roll over. For many babies this starts around 8 to 12 weeks, but some begin earlier. A swaddled baby who rolls onto their tummy can't use their arms to reposition themselves.
To transition, try swaddling with one arm out for a few nights, then both arms out, or move to a baby sleeping bag.
The best fabric for a swaddle
Fabric matters more than most people realise. A swaddle sits against your baby's skin for hours, so look for:
- Breathability. Loose-weave muslin and organic cotton let air circulate, which lowers the risk of overheating.
- Softness that lasts. Good cotton gets softer with every wash rather than pilling.
- Gentle on skin. Organic cotton is grown without synthetic pesticides, which matters for delicate newborn skin.
- A generous size. Around 120 × 120 cm gives enough fabric to wrap securely, and to keep using the swaddle long after the newborn stage.
Beyond the swaddle: why we love a multi-use cloth
The Lemej Swaddle Sets are made of soft organic cotton, in prints you'll be happy to see draped across the pram or over your shoulder. When the swaddling weeks are over, they don't disappear into a drawer. They become a light blanket, a burp cloth, a sunshade, a changing mat on the go, and one day a favourite comfort blanket.
For calm moments during the day, pair it with our wool-silk Pacifier Cloth. It keeps the pacifier close and gives small hands something soft to hold, so it's less likely to end up on the café floor.
A note on sleep: keep your baby's sleep space clear. That means no loose blankets, cloths or soft toys in the cot for the first 12 months. Save the pacifier cloth for supervised cuddles, the pram and time on your lap.
You'll find your rhythm
Your first swaddle might look more like a burrito that's come undone. That's fine. By the end of the first week your hands will know the folds by heart, often in the dark.

Frequently asked questions
How tight should a swaddle be? Snug around the chest, so you can fit two or three fingers between the fabric and your baby, and loose at the hips so the legs can bend up and out.
Can I swaddle my baby at night? Yes, as long as your baby sleeps on their back, the fabric is breathable, the room isn't too warm and you stop swaddling once your baby starts trying to roll.
When should I stop swaddling? As soon as your baby shows signs of rolling. This often happens between 8 and 12 weeks, sometimes earlier.
What's the best fabric for a swaddle? A breathable natural fabric, such as organic cotton or cotton muslin, that stays soft after washing and is large enough (around 120 × 120 cm) to wrap securely.
