See what everyone's talking about! 

Our award winning Transitional Swaddle Sack® is the solution that parents have been searching for, and it’s designed by a nurse! It features uniquely shaped 1/2 length arms up sleeves with fold over mitten cuffs that may be worn open or closed. With the mitten cuffs closed, the specially designed sleeves provide partial suppression of the Moro (startle) reflex, and the Transitional Swaddle Sack is an important safer sleep option for babies who can roll over because the sleeves allow enough mobility for baby to use their arms to push up and reposition their head if they roll over.

Our Transitional Swaddle Sack is deemed Hip Healthy by the International Hip Dysplasia Institute, because it allows room for baby's hips and knees to flex and move, while still offering support.

It's easy to use! Fold the mitten cuffs closed, unzip the sack and place baby onto the sack. First, place arms into sleeves, and next, place baby’s legs into sack and simply zip up. Baby's arms will be in a flexed position close to body. The closed cuffs also protect from facial scratches. 

As baby grows and develops, you may choose to open a cuff, so baby may suck on fingers. Babies who can self- soothe are calmer and sleep better. Leave sleeve opening at wrist. If baby stretches and fully extends arm, the sleeve will be elbow length.

The sack’s ergonomic design features a snug midsection to provide snugness to reassure and comfort baby.

The Transitional Swaddle Sack features a 2-way/2 pull zipper, so diaper changes are easy. Just unzip from the foot to access the diaper.

The Transitional Swaddle Sack is designed to bridge the gap from classic snug swaddling to loose fitting sleeping sack.  When baby is ready to transition from a snug swaddle or can roll over, but doesn’t sleep well in a sleeveless sleep sack due to baby still has a strong Moro (startle) reflex, the Transitional Swaddle Sack is the perfect solution for a good night’s sleep and peace of mind.

Our Transitional Swaddle Sack is convertible and easy to use. It's great for babies who prefer to sleep with arms up and for babies who like to self-soothe on their fingers.

Layering for extra warmth:

A cotton bodysuit may be worn underneath as a light extra layer if needed for a bit more warmth.

A wearable blanket, such as our zzZipMe Sleeping Sack may be worn over top if more warmth is needed. Our zzZipMe Sacks are available in a range of TOGs for different levels of added warmth for different environmental temperatures.

Do not use thick, polyester fleece pajamas under the Transitional Swaddle Sack. Cotton is best next to baby’s skin and no added thickness should be used under the TSS.

Keep growing in the right direction

A perfect product in every stitch. My baby knows what she likes best and she showed me that arms up is what she wants. With this swaddler, everybody's happy.

So amazing, I just ordered more! Unlike my oldest, this one punches and kicks right out of his swaddle blanket, but this makes sure he stays warm and cozy while it keeps him nice and calm too.

Comfy baby sleeps almost all night

I have been giving these as gifts to all my mom-friends since I got it. I was worried about keeping my 2-month-old after he learned to push himself over so I bought one of these and WOW!

Must have for baby

Great for babies that like the swaddle but not on their arms. You can cover the hands so they can't scratch, or let them free to suck their fingers. So lightweight and so much cheaper than the other brands too!

Great Swaddle Sack!

Switched to this after using the Swaddle Up because my daughter was showing signs of attempting to roll over. She won't take a pacifier either so she needs her hands to calm herself down. Can't believe this saved our sleep so inexpensively. Save yourself $ and Z's and just buy it already!
