A good swaddle is one of the simplest ways to help a newborn settle. It recreates the snug feeling of the womb, calms the startle (Moro) reflex that wakes babies mid-nap, and teaches their tiny arms to stay tucked instead of flailing. But a loose or incorrectly wrapped swaddle defeats the purpose — so follow this step-by-step guide and practise until it takes you under a minute.
What You Need
A large, thin blanket (around 100 x 100 cm works best), or a purpose-made swaddle wrap with Velcro or zip. Muslin is ideal — breathable, light, and forgiving for beginners.
How to Swaddle a Baby, Step by Step
Step 1: Lay the blanket diamond-style
Spread the blanket flat on a firm surface with one corner pointing up, like a diamond. Fold the top corner down about 15 cm to form a straight edge across the top.
Step 2: Position the baby
Lay your baby face-up on the blanket so the folded edge sits level with their shoulders and their head stays completely above the blanket. Arms can go along the body for a snug wrap, or one/both out if they prefer their hands near their face.
Step 3: Bring the first side across
Straighten the baby’s left arm gently against their side. Take the right corner of the blanket, bring it firmly across the body, and tuck it under the opposite side — behind the back. This is the anchor; it should feel snug.
Step 4: Fold up the bottom
Take the bottom corner and fold it up over the feet, tucking it loosely into the top of the wrap behind the shoulders. Leave room for the legs to bend and the hips to move — the legs should be able to splay like a frog. Forcing legs straight and tight can harm developing hips.
Step 5: Bring the second side across and finish
Take the remaining corner, bring it firmly across the chest, and tuck it behind the back. Check the fit: the wrap should be snug around the arms but loose enough to fit two to three fingers between the blanket and the baby’s chest.
How Long Should You Swaddle?
Most babies enjoy swaddling from birth until they show signs of rolling over, typically around 2–3 months. You may notice your baby beginning to break out of the wrap, sleep equally well without it, or resist being wrapped — these are all signals to transition. Move to a sleep sack with armholes, which keeps the feeling of cosiness without restricting the arms. Some families transition gradually: one arm out for a few nights, then both.
Swaddle Safety Rules
- Back to sleep, always. Swaddled babies must only ever be placed on their backs.
- Stop swaddling at the first sign of rolling — usually around 2 months. A swaddled baby who rolls face-down cannot push up to breathe. Transition to a sleep sack.
- Never cover the head or face, and keep the room at a comfortable temperature so the baby does not overheat — one light layer underneath is usually enough indoors.
- Leave the hips loose. Tight swaddling that pins the legs straight is linked to hip dysplasia; look for “hip-healthy” technique or use a purpose-made swaddle.
Troubleshooting: My Baby Hates the Swaddle
Some babies genuinely dislike being wrapped. Try one arm out, a looser wrap, or a sleep sack instead — the goal is a calm baby, not a perfect technique. If your little one fights the swaddle every time, forcing it is not worth the stress. And if night-time settling is the issue, our guide to why babies cry when put down to sleep covers the other common causes.
