Learn how to swaddle a newborn with a breathable muslin wrap in five safe steps, including fit checks and tips for warmer rooms.

Quick answer

Lay a large muslin swaddle flat in a diamond shape, fold the top corner down, place your baby with shoulders at the fold, and wrap one side at a time across the chest and under the back. Keep the hips loose and stop if the room is very warm or your baby shows signs of overheating.

Why muslin works well for swaddling—and when it doesn't

Muslin's open weave lets air move through the fabric, which makes it a practical choice for swaddling in warmer rooms or for babies who run hot. Unlike stretchy jersey wraps, muslin has less give, so you'll rely on a generous size and careful folding rather than tension to keep the wrap secure.

That same breathability doesn't make overheating impossible. If the room is above roughly 75°F (24°C), or your baby feels clammy or flushed, use a single lightweight layer and skip extra blankets. A muslin swaddle is not a substitute for following safe-sleep guidance: always place your baby on their back on a firm surface, and stop swaddling once your baby shows signs of rolling.

5-step muslin swaddle routine

Prep the wrap and the room: Lay the muslin swaddle flat in a diamond shape and fold the top corner down about 6 inches. Check that the room is comfortably cool and that your baby isn't dressed too warmly underneath. Common mistake: skipping the room check. If the room feels warm to you, dress your baby in just a diaper and a light onesie before swaddling.
Position your baby: Place your baby face-up with their shoulders at the folded edge, so the fabric sits at neck height—not over the chin or mouth. Keep one hand gently on your baby's chest for comfort. Checkpoint: the wrap should never cover the mouth or nose. If it rides up, refold the top edge lower.
Wrap the first side: Bring the left corner across your baby's chest and tuck it under the right side of their back. Keep the fabric snug across the torso but not tight enough to restrict breathing. Common mistake: pulling too tight. You should be able to slide a hand between the wrap and your baby's chest.
Wrap the second side: Bring the right corner across the chest and tuck it under the left side. Then fold the bottom corner up over the feet, leaving room for the legs to bend outward at the hips. Checkpoint: hips and knees should be able to flex freely. A tight, straight-legged wrap can stress the hip joints.
Do a final safety check: Slide two fingers under the wrap at the chest and neck. Make sure the fabric is smooth, not bunched, and that your baby's arms are either inside or comfortably outside—never pinned awkwardly. Stop swaddling for sleep once your baby starts trying to roll. If you notice sweating, damp hair, or a heat rash, remove the swaddle and cool the room.
