Swaddle your baby by laying them face-up on a thin blanket, wrapping each side snugly around the torso while keeping the hips loose, and stopping as soon as rolling begins.
Swaddling is a classic way to calm a newborn and encourage longer sleep, but the technique matters as much as the blanket itself. A wrong fold or a too-tight wrap can create real hazards, so learning the correct sequence — and knowing when to stop — is what keeps this age-old comfort practice safe.
What You Need Before You Start
You only need one thing: a thin, lightweight blanket. Receiving blankets or muslin swaddles work well because they let heat escape. Skip thick quilts and avoid weighted swaddles entirely, as they can interfere with a baby’s breathing.
Before wrapping, make sure the room is a comfortable temperature and the baby is dressed in light layers underneath. Overheating is a genuine risk, so if you’re unsure, fewer layers are better.
How to Swaddle Your Baby Step by Step
Follow this sequence on a flat, safe surface. Every fold has a purpose.
- Spread the blanket flat in a diamond shape, then fold the top corner down to create a straight edge along the top.
- Place the baby on their back with their shoulders just below that folded edge and their head above it. The head must stay uncovered.
- Bring one side corner across the body and tuck it under the opposite side, securing it snugly around the torso.
- Fold the bottom corner up over the legs and tuck it. This is where the “loose” part matters: the fabric must not cover the face, and the hips and knees need room to bend and turn outward.
- Bring the remaining side corner across and tuck it securely so the wrap stays in place through the night.
You’ll know you’ve done it right when the baby’s arms are snug but their legs can still move freely. A swaddle that’s too tight around the hips can contribute to hip dysplasia, so let those legs bend.
Swaddle Safety Rules and When to Stop
These rules are non-negotiable for safe sleep. Swaddled babies must always be placed on their backs — never on the side or stomach, as that position raises the risk of suffocation.
Stop swaddling as soon as you see any signs of rolling over. Once a baby can roll, a swaddle becomes a restraint that keeps them from getting back to a safe position. At that point, a sleep sack is the safer alternative.
- Watch for overheating: sweating, flushed cheeks, heat rash, damp hair, or rapid breathing all mean the baby is too warm.
- Never cover the face or neck: loose fabric near the airway is a suffocation hazard.
- Make it snug, not tight: the wrap should stay put without restricting the chest or hips.
- Hips and knees stay loose: they should bend and turn outward naturally.

FAQs
How can I tell if my baby is too warm while swaddled?
Check for damp hair, flushed cheeks, sweating, or rapid breathing. If you notice any of these signs, remove a layer or use a thinner blanket, and check the room temperature to keep your baby comfortable.
Can I swaddle my baby through the night?
Yes, as long as the baby is on their back and the swaddle is snug around the torso but loose enough for the hips to move. Stop swaddling as soon as your baby shows signs of rolling over, or by around 2 months, whichever comes first.
What should I use instead of a swaddle once my baby starts rolling?
Once rolling begins, transition to a sleep sack. A sleep sack keeps the baby warm without wrapping the arms, so they can move freely and safely reposition themselves during sleep without the risk a loose swaddle creates.
