Learn the safe swaddle technique with a muslin swaddle blanket. Step-by-step instructions for newborn swaddling, plus baby sleep safety tips.

Quick Answer

To swaddle safely, lay the muslin blanket in a diamond shape, fold down the top corner, place your baby with shoulders at the fold, wrap each side snugly, and tuck the bottom flap loosely. Always stop swaddling once your baby shows signs of rolling.

Why Muslin Works Well for Swaddling

Muslin swaddle blankets are lightweight and breathable, which helps reduce the risk of overheating during sleep. The 47" x 47" size provides enough fabric to create a secure wrap without excessive bulk.

Because muslin is a looser weave, it allows air to circulate, making it a good choice for warmer climates or babies who tend to run warm. However, the fabric can be less stretchy than knit swaddles, so you need to wrap it carefully to avoid loosening during the night.

When to Stop Swaddling

The American Academy of Pediatrics recommends stopping swaddling as soon as your baby shows signs of trying to roll over, usually around 2 to 4 months. Swaddling after rolling increases the risk of suffocation.

Once you stop swaddling, you can transition to a sleep sack or a wearable blanket to keep your baby warm without loose bedding.

Step-by-Step Safe Swaddle Technique

Step 1: Position the Blanket in a Diamond: Lay the muslin swaddle blanket flat on a safe surface with one corner pointing up, forming a diamond shape. Fold the top corner down about 6 inches to create a straight edge for your baby's shoulders. Make sure the fold is even so both sides are symmetrical.
Step 2: Place Your Baby with Shoulders at the Fold: Lay your baby on their back with their shoulders aligned with the folded edge. Their head should rest above the fold, leaving their face uncovered. Keep their arms down by their sides or slightly bent across the chest. Your baby's face must always be visible and unobstructed.
Step 3: Wrap the Right Side Snugly: Take the right corner of the blanket and pull it across your baby's chest, tucking it securely under their left arm and behind their back. Ensure the wrap is snug but not tight enough to restrict breathing or hip movement. You should be able to slip two fingers between the blanket and your baby's chest.
Step 4: Fold Up the Bottom Flap Loosely: Fold the bottom corner of the blanket up over your baby's feet and tuck it loosely under their chin or behind their back. Leave enough room for your baby's legs to bend and move freely at the hips. The bottom must be loose to prevent hip dysplasia and allow natural leg movement.
Step 5: Wrap the Left Side and Check for Safety: Bring the left corner of the blanket across your baby's chest and tuck it securely under their right side. Check that the swaddle is snug, your baby's hips can move, and the blanket is not covering their face. Always place your baby on their back to sleep and stop swaddling once they start showing signs of rolling.
