Learn how to swaddle your newborn safely and effectively using a muslin wrap. This step-by-step guide covers setup, wrapping, and common mistakes to avoid.

Quick answer

Swaddle your newborn by laying the muslin flat, folding one corner, placing baby on their back, and wrapping each side snugly but not too tight. Choose a lightweight, breathable fabric like bamboo or organic cotton to reduce overheating risk.

Why fabric choice matters for safe swaddling

The fabric you use directly affects how well your baby regulates temperature and how secure the wrap feels. Bamboo swaddles are ultra-soft and breathable with an open weave that helps prevent overheating. Organic cotton muslin is lightweight and extra large (120cm x 120cm), making it easier to achieve a snug fit without gaps. Both options are versatile enough for feeding, strolling, or using as a buggy cover.

Avoid heavy or non-breathable fabrics. A swaddle that traps heat can increase the risk of overheating, which is linked to SIDS. Always choose a fabric that allows air circulation.

Step-by-step swaddling guide

  1. Step 1: Lay the muslin flat in a diamond shape: Spread the swaddle blanket on a flat, safe surface like a changing table or the floor. Fold the top corner down about 6 inches to create a straight edge. The baby's head will rest above this fold. Make sure the fold is even so the fabric doesn't bunch near the face.
  2. Step 2: Position baby on their back: Place your newborn on their back with their shoulders just below the folded edge. Their head should be above the fold, not covered. Keeping baby on their back is essential for safe sleep. Never swaddle a baby who sleeps on their stomach.
  3. Step 3: Wrap the right side across the body: Take the right corner of the muslin and bring it across your baby's chest, tucking it snugly under their left arm and behind their back. Leave the right arm either inside or outside the wrap depending on your baby's preference—some newborns sleep better with arms free. If baby startles easily, tuck the arm inside; if they fuss, leave it out.
  4. Step 4: Fold the bottom up: Bring the bottom corner of the muslin up over your baby's feet and tuck it loosely under the chin. Leave enough room for hip movement—tight hips can cause hip dysplasia. The legs should be able to bend and splay naturally. Check that you can slide two fingers between the swaddle and baby's chest.
  5. Step 5: Wrap the left side across and secure: Take the left corner and bring it across the body, tucking it under the baby's right side. Ensure the fabric is smooth and not twisted. The final wrap should be snug enough that the baby can't break free but loose enough for natural leg movement. A too-loose swaddle is a suffocation risk; a too-tight one restricts breathing.
