Quick answer: Lay the swaddle flat in a diamond shape. Fold the top corner down to make a small triangle along the top edge. Place baby on the swaddle with shoulders just below the fold line. Pull the left corner across baby's chest and tuck under the opposite side. Bring the bottom corner up over baby's feet. Pull the right corner across and tuck snugly under baby's back. Done correctly, the wrap is firm at the chest and loose enough at the hips for legs to bend up and out.
If you've never swaddled before, the first few attempts can feel like wrapping a wiggly burrito. With practice, it takes less than a minute. Here's the step-by-step.
What you need
- One swaddle blanket, preferably square (around 47" × 47") and made from breathable fabric like muslin
- A flat surface — bed, changing table, or even the floor
- A calm baby — try swaddling between feedings, not during a meltdown
Step-by-step: the diamond fold technique
This is the standard swaddling method most pediatricians and nurses teach.
- Lay the swaddle flat in a diamond shape. One corner pointing up, one down, one each to the sides.
- Fold the top corner down about 6 inches. This creates a flat top edge along the upper third of the diamond.
- Place your baby on the swaddle with their shoulders just below the fold line. The fold should hit at the back of their neck — not over their face.
- Hold the baby's right arm gently against their body. Take the left corner of the swaddle and pull it firmly across their chest. Tuck the corner under their back (under the opposite side). Their right arm is now wrapped against their body.
- Fold the bottom corner up over their feet. Loosely — you want their legs to be able to bend up into a frog position.
- Hold the baby's left arm against their body. Take the right corner and pull it firmly across their chest, going around to the back. Tuck the corner under.
- Check the wrap. It should be snug at the chest (you can fit two fingers between the wrap and baby's chest) and loose at the hips (legs can bend up and out).
That's it. The whole thing takes 30–60 seconds with practice.
The quick burrito method
For experienced parents who want speed:
- Lay the swaddle flat in a square.
- Fold the top edge down a few inches.
- Place baby on the swaddle with shoulders at the fold.
- Wrap the left side across, tuck under.
- Bring the bottom up.
- Wrap the right side across, tuck under.
Same idea, less precision. Works once you've got the muscle memory.
Safety checks before every swaddle
After you wrap, check these three things:
Chest snugness: Fit two fingers between the wrap and your baby's chest. Tighter than that, and breathing can be restricted. Looser, and the wrap can come undone.
Hip looseness: Your baby's legs should be able to bend up and out into a "frog" or "M" position. Over-tight hip wrapping has been linked to hip dysplasia. The hips should always be loose enough to move freely.
Position for sleep: Always place a swaddled baby on their back. Never on the side or stomach.
Troubleshooting
My baby breaks out of every swaddle within minutes.
Either the wrap is too loose, or your baby just doesn't like swaddling. Try wrapping firmer (especially the under-tuck on each side), or consider a fitted swaddle with velcro or zippers.
My baby cries harder when I swaddle them.
Some babies hate the constraint. Try a transitional swaddle with one arm out, or skip swaddling entirely. Not every baby benefits from swaddling.
The swaddle feels too hot.
Switch to lighter muslin (if you're using flannel or fleece), reduce baby's clothing layer underneath to just a onesie, or check the room temperature (aim for 68–72°F).
I can't get the corners to stay tucked.
Practice. The under-tuck is the part that holds everything together. Make sure you're tucking the corner all the way under your baby, not just under the swaddle.
When to stop using this technique
Stop swaddling once your baby shows signs of rolling — typically 2–4 months. Even an attempt to roll is enough reason to stop, since a swaddled baby can't push up safely if face-down.

Frequently asked questions
What's the easiest swaddle for beginners?
A fitted swaddle with velcro or zippers (sometimes called a "swaddle wrap") removes the technique entirely — you just slip your baby in and fasten. Trade-off: they're single-purpose (only good for swaddling) and don't grow with your baby.
How tight should a swaddle be?
Snug at the chest (two-finger rule), loose at the hips (legs can bend up and out). Never tight enough to restrict breathing or hip movement.
Can I swaddle a newborn right after they're born?
Yes. Hospitals usually swaddle newborns within minutes of birth as part of the standard postpartum routine. You can continue at home from day one.
What if my swaddle keeps coming undone?
Most often it's the under-tuck that's the issue. Make sure you're pulling each corner all the way around your baby's back and tucking it firmly under. If your fabric is too slippery, switch to a textured muslin that grips itself.
Does the fabric matter?
A lot. Breathable fabric (muslin, light cotton) prevents overheating. Heavy fabrics (flannel, fleece) can trap heat dangerously. Always choose breathable.
Need a swaddle to practice with?
Our muslin swaddles are sized at the standard 47" × 47" — large enough for the diamond fold technique without bulk. They're textured enough to hold a tuck and breathable enough for safe sleep. Browse boys swaddles, girls swaddles, or matching swaddle sets for designs you'll actually want in your nursery photos.
