How to Swaddle a Newborn: Traditional Fold vs Zip Swaddle (Step by Step)

By the Tinytato Team · Updated October 2026 · 6 min read

The confinement lady makes it look easy. Fold, tuck, fold, done, and baby sleeps like a little popiah.

Then she goes home. It's 3am, you have a wriggling newborn and a square of cloth, and nothing stays where you put it.

Here are both methods, step by step: the traditional fold, and the zip swaddle for nights when you are too tired to fold anything.

Why swaddle a newborn?

A newborn has spent months curled up in a tight space. Out here, a sudden noise or movement sets off the startle reflex (kaget): arms fly out, baby jolts awake and the crying starts again.

A swaddle holds the arms close so the startle doesn't wake baby as easily. The American Academy of Pediatrics says that when it is done correctly, swaddling can help calm a newborn and support sleep.

Swaddling is optional. Some babies love it and some hate it. If yours sleeps well without one, that is fine too.

How do I swaddle a newborn with a blanket? (Traditional fold)

Lay baby on a thin square cloth, fold the arms in one side at a time, and leave the bottom loose so the legs can bend. You need a thin, square cloth, about 100 to 120 cm on each side. A cotton or bamboo muslin works well. These steps follow the hip-healthy method from the International Hip Dysplasia Institute.

1. Make a diamond. Lay the cloth flat with one corner pointing up. Fold that top corner down about 15 cm to make a straight edge.
2. Place baby. Lay baby on their back with their shoulders just below the folded edge.
3. Wrap the first side. Hold baby's left arm straight and gently down by their side. Bring the left side of the cloth across the arm and chest and tuck it under baby's right side.
4. Bring up the bottom. Fold the bottom corner up loosely over the feet. Leave plenty of room: the legs should bend up and out like a frog.
5. Wrap the second side. Hold the right arm down, bring the right side of the cloth across, and tuck it under baby's back. Baby's weight holds it in place.
6. Check. Two fingers fit between cloth and chest. The cloth is below the chin and clear of the face. The legs can bend and move.

It takes practice. Most parents need a week or two of nights before it stops coming loose.

How do I use a zip swaddle, step by step?

Lay baby inside, settle the arms, and zip up to just below the chin. A zip swaddle is a sleeping bag shaped to hold baby's arms close, so there is no folding.

1. Open the zip fully and lay the swaddle flat.
2. Lay baby on their back inside, shoulders level with the neckline.
3. Settle the arms into the position the swaddle is shaped for. In a TatoWrap, the arms rest up near the face.
4. Zip up. Stop below the chin.
5. Check the neckline is not loose enough to slip over baby's mouth, and that the legs have room at the bottom.

That's it. At 2am, a two-way zip also means you can open the bottom for a nappy change without unzipping the top.

“It's very easy to use, especially during night…diaper changes”

Cloth swaddle vs zip swaddle: which is easier?

A zip swaddle is easier and stays on all night; a cloth swaddle is cheaper and more versatile but takes practice.

	Cloth swaddle (folded)	Zip swaddle
Skill needed	Takes practice	None. Zip and check
Stays on at night	Can come loose as baby wriggles	Can't unwrap
Nappy change at 2am	Unwrap and rewrap	Open from the bottom (two-way zip)
Room for hips	Depends on how you fold the bottom	Built-in room at the bottom
Fits as baby grows	One cloth fits for months	Sized by age; move up a size
Daytime uses	Burp cloth, nursing cover, shade	Sleep only
Cost	Lower	Higher

Many families use both: a zip swaddle for the cot, and the muslins in the day. We compare them in more detail in Muslin swaddle vs zip swaddle.

How tight should a swaddle be?

Snug at the chest, loose at the hips.

• Chest: two fingers fit between the fabric and baby. Tighter than that and breathing is restricted. Looser and the cloth can work up to the face.
• Hips and legs: the legs should be able to bend up and out at the hips. The International Hip Dysplasia Institute warns that wrapping the legs straight down and pressed together may increase the risk of hip dysplasia.
• Neck and face: fabric stays below the chin.

Old habits say to straighten baby's legs "so they grow straight". Please don't. More on this in Is swaddling bad for baby's hips?

Loose hips matter more than most parents realise. In 1975 Japan ran a national campaign against wrapping babies with their legs held straight. Hip dislocation in babies fell from as high as 3.5% to under 0.2%, according to the International Hip Dysplasia Institute.

Why does my baby break out of the swaddle?

• The arms aren't held. If the first wrap is loose, a strong newborn pulls an arm free in minutes.
• Baby wants hands near the face. Many babies suck their fingers or touch their face to settle. Arms pinned straight down can make them fight. See Swaddle arms up or down?
• Baby is too hot. A sweaty baby wriggles. In Malaysia, check the layers underneath (see What should baby wear under a swaddle in aircond?).
• Baby is ready to stop. Rolling attempts and constant breakouts are signs. See When to stop swaddling.

Is swaddling safe? 5 rules for safe swaddling

Yes, when it is done correctly. Follow these every time:

• Always on the back to sleep, on a firm, flat cot mattress. The AAP says this matters even more when baby is swaddled.
• Nothing else in the cot: no loose blankets, pillows or bolsters.
• No weighted swaddles.
• Watch for overheating: sweating, damp hair, flushed cheeks, heat rash or fast breathing.
• Stop arms-in swaddling as soon as baby shows signs of trying to roll. Some start as early as 2 months.

Can a newborn sleep without a swaddle?

Yes. Swaddling is optional, and a baby who sleeps well unswaddled doesn't need one. Swaddling is a settling tool, not a requirement, and the AAP says wearable blankets that don't swaddle and let baby move freely can be used for as long as you like. If you don't swaddle, put baby down on their back in a clear cot, dressed in a onesie or a sleeping bag that suits the room temperature.

Frequently asked questions about swaddling a newborn

Quick answers to what parents ask most.

How many hours a day should a newborn be swaddled?

Swaddle for sleep: naps and night-time. When baby is awake, feeding or having tummy time, take the swaddle off so they can move their arms and legs freely.

What is the easiest way to swaddle a baby?

A zip swaddle. There is no folding, it cannot unwrap in the night, and you can do it in the dark.

Should I swaddle with arms up or down?

Either can be safe. The AAP says there is no evidence on SIDS risk either way. Choose the one your baby settles in, and keep the hips loose.

Can I swaddle my baby for daytime naps?

Yes, with the same rules as at night: on the back, in a clear cot, and checked for overheating.

Is it OK to swaddle in a hot room?

Yes, with fewer layers. On a hot night with just a fan, a nappy under a light swaddle is enough. If baby's chest is hot or sweaty, leave the swaddle off for that sleep.
