How To Swaddle Your Baby

Learn the easiest and safest ways to swaddle your newborn.

Have your attempts to swaddle your baby left you bewildered? Do you need help getting your baby as snug as a bug?

The womb was their home for nine months — warm, safe, and secure. Once they’re born, the world can be new, cold, and scary.

Swaddling helps ease this transition by recreating the secure warmth of the womb and can leave you with a happier baby overall. So how do you keep your little one nicely tucked in without the struggle?

How To Swaddle Your Baby

Making your baby into a mini burrito can be the fast-track to a happy sleeper, but only if you can do it correctly and safely!

Having loose objects near your infant increases the chance of Sudden Infant Death Syndrome — better known as SIDS. These loose objects can include blankets, pillows, and toys.

Swaddling offers an alternative to a loose blanket by creating a tight wrapping around them that will not slip or cover their face (1).

A safe swaddle is one tight enough to hold their limbs secure and give them pleasant confinement, but not so tight that they struggle to kick their legs and have their circulation cut off.

Swaddling safety should be observed at all times — here are a few key rules to follow:

  • Never place a swaddled baby on an uneven or sloped surface.
  • Always lay your swaddled baby on their back.
  • Check on your swaddled baby every so often.
  • Monitor your baby’s temperature, especially when swaddling in the summer.

How to Swaddle Arms Down

The most traditional swaddle is where a baby has their arms straight against their sides and neatly tucked into the wrap. Babies love this because of the warmth and security it provides them.

How to Swaddle Baby with Swaddle Blanket

1. Prepare your blanket

Put your swaddling blanket on a flat surface such as a bed or even the floor so it looks like a diamond. Pull the top corner down — it doesn’t need to go all the way down, just enough to create a flat edge for your baby.

2. Lay your baby down

Place your baby face up with their shoulders aligned to the folded edge of the blanket, so their head and neck are outside of the swaddle. You don’t want the folds coming up and covering their mouth or nose, or nuzzling their cheek.

Babies may confuse the softness of the swaddle on their face as a food source and grow irritated when no milk appears.

3. Perform the first fold

Hold down your baby’s left arm and pull the left side of the blanket over their torso, tucking it under their right side. You’ll get the second arm when you pull the other side over.

4. Bring the bottom up

Pull the bottom of the blanket up and over your baby’s legs, and tuck it behind their right shoulder. Don’t make the little foot sack too tight.

Make sure your baby is bow-legged and able to move around a bit without disturbing the security of the wrap.

5. Perform the final fold

Hold your baby’s right arm across their body and pull the final blanket flap over your baby’s body, tucking the end behind the left-hand side. Both arms will be pinned to their sides and the wrap nice and tight around their body.

You now have a happy, swaddled baby!

How to Swaddle Arms Up

Babies love to be swaddled, but they can’t do it forever. Weaning your baby from swaddling can be difficult, so starting the process early by letting your baby have their arms out can help ease the transition.

Letting their arms out of the swaddle gets them used to the feeling of freedom, grow their muscles, and learn how to self-soothe.

1. Lay out your blanket

Lay your blanket on a flat surface so it makes the shape of a diamond. Fold down the top corner of your diamond to the middle of your blanket — this will be a deeper fold than if you’re swaddling with your baby’s arms in.

You’re trying to make the blanket smaller since part of your baby’s body will be out of the swaddle to allow for arm movement.

2. Lay baby in the blanket

Place your baby with their upper back on the fold, so their shoulders, neck, and head are above the fold. When you pull the blanket flaps around, they should go right below your baby’s armpits.

3. Tuck the left corner

Pull the left corner of the blanket over your baby’s chest and tuck it behind their right-hand side, holding their left arm up gently.

You’ll repeat the same action you did for the arms down swaddle, but instead of straightening your baby’s arm down against their body inside of the blanket, you gently lift it up and away from the wrap.

4. Pull the bottom blanket up

Pull the bottom of the blanket up and rest it on the middle of your baby’s tummy. Pull it securely around their legs, leaving enough room to kick a bit. This will be secured once you pull the last flap around.

5. Complete the swaddle

Wrap the right corner of the swaddle around your baby’s tummy and tightly tuck it under their left-hand side while holding their right arm up out of the tuck.

Once they are swaddled securely with their arms free, they’ll feel snug and secure but still have that upper movement.

Swaddling With Velcro Or Zipper Blankets

Some companies have ready-made sleep sacks available. These are blankets designed for easy swaddling, with a pocket for the baby’s legs and wrap-around velcro arms.

Blankets like this are great to have on hand because they make swaddling incredibly easy to accomplish.

With sleep sacks, you can tuck your baby in with 3 short steps.

1. Place baby’s feet

Place your baby’s feet into the pre-existing sack. If there’s a zipper on the sack, make sure you zip it to enclose your baby in the swaddle alternatively leaving it open can let your baby kick, play, and develop those leg muscles.

2. Engage the velcro

By looking at the velcro pads on the swaddler, you tell which to pull over first. The flap with the velcro on the outside should be the one you pull over your baby’s chest first and tuck it underneath them.

3. Secure the second flap

Secure the other flap with the velcro sticky pad on the other side of the baby. Once you’ve pulled the second flap securely over the first, press the two velcro pads together.

Be careful that you haven’t made the swaddle too tight!

Ready, Set… Swaddle!

Now you know how to swaddle like a pro, you’re on the road to a soothed, happy baby. Swaddling is a tool to comfort babies and give their parents peace of mind, so don’t be afraid to take advantage of it — remember, practice makes perfect!
