We love it!

"Our baby started rolling pretty early so we were forced to stop swaddling. But that Moro reflex was still strong and led to a lot of disturbed sleep for our little one. This is perfect for our baby as it stops the startle reflex and allows everyone to get restful sleep. We’re even purchasing another to use at daycare! We highly recommend this! We love it!"

Win, win for all of us!

My 3 month old hated to be swaddled and always broke free of every kind we tried. We wanted to try and transition him out of it, and we tried so many different products and none worked as well as the Swaddle Sleeves Sack! The weighted arms helped with his startle reflex and he still could have his arms free. Win, win for all of us! Day 2 it only took 5 minutes for him to put himself to sleep! I am one happy and proud mama! Thank you for a great product and coming to our rescue--just wish I would have found this sooner!"

Mama LOVES her sleep!

"I had significant anxiety about transitioning my swaddling-loving 4 month old. I bought every type of swaddle and transitional item on the market (Mama LOVES her sleep!) and this was the one that did it and had him sleeping soundlessly through the night after two days."

My swaddle loving baby slept amazing in this!

I was so skeptical about this sleep sack, especially because I hadn’t even heard of it before one of my good friends suggested it to me. Let me start by saying my baby absolutely LOVED her swaddle. I bought this sack to use when we were ready to transition from it. She was sleeping 10-11 hour stretches in her swaddle and I was terrified to take her out of it. Well, yesterday at 11.5 weeks she rolled over and we knew we had to stop right away. Insert swaddle sleeves. I was so anxious when we laid her down but she was out right away. I’m typing this now as I nurse her at 6:20am, after she slept NINE hours straight!!!!! No wakes. I know she can sleep longer than this, but for her first night without her beloved swaddle I am so impressed and happy. The swaddle may not even be missed after all! She was so peaceful all night. We actually noticed more restlessness before swaddle sleeves. 10/10, worth every penny, will be buying the next size up when it’s time!! Thank you swaddle sleeves for making what was going to probably be the worst night ever so easy!

Life Changing Product

My baby boy hated having his arms swaddled since he was a week old. He is a super busy little man with a strong Moro reflex. This is where the swaddle sleeves have been life changing for us. As soon as we started using them he started to wake only once a night for feeding and would fall right back asleep. Even on days that he is cranky during the day, as soon as we put him in his swaddle sleeves sack or bodysuit he settles and falls asleep. At two months old he had his first full night sleep! In my opinion, swaddle sleeves are a miracle! We already have the next size up on stand by. As you can see in the photos my little man approves!

Great transitional swaddle

Had trouble getting my daughter from being swaddled to arms out on her own! This swaddle helps her startle reflex and keeps her asleep longer!!

Great transition sleep sack

Great way to use as a transition way from swaddling to out. Our LO has been rolling in his swaddle and the swaddles sleeves helped so much in his startle reflex. He's now been able to freely roll over to his tummy and mostly sleep all throughout the night!

Celeste Miller

Our baby hated being swaddled, but clearly had a startle reflex still so we needed a solution. This has been amazing for our sleep!!! He’s happy, we are happy, sleeping great and babe loves to be able to move arms around. Transitioning out of the swaddle hasn’t been awful all thanks to this!

Sleeping like a champ!

I was worried about the transition from Snoo to our crib, but the swaddle sleeves sleepsack was recommended and boy do we love it! This is after night #1! He’s been sleeping like a champ in his sleepsack and it’s been a smoother transition than I would have imagined!

Baby loves it

I’ve been so anxious knowing that baby would soon have to cut ties with her love to dream swaddle. She was obsessed with the arms up/hands over her face sleep position since she was born. Now that she is 5 months and rolling over I knew we had to transition but the thought of disrupting a baby who has slept 12 hours a night for months had me terrified. Today was day one in her swaddle sleeves and she seems to love it! She cried for a few minutes missing her usual sleep position but I think she adjusted pretty quickly to this and hasn’t woken up since I put her down for the night! Thanks swaddle sleeves for this genius product.

Started sleeping through the night!

I got this sleep sack when I was struggling to get my little one to sleep through the night and knew he needed to transition soon out of his swaddle with his arms in. I’m not sure if it was the swaddle or just an amazing coincidence, but shortly after we started using this he started sleeping through the night!! I’m also happy this can grow with him with the adjustable/removable sleeves!

Baby loves it!

This was the easiest transition from swaddle to sleep sack! My baby absolutely loves this and is sleeping 11-12 hours a night!

Helpful swaddle transition

The weighted swaddle sleeves are a helpful transition item out of the swaddle. I love that the sleep sack comes with regular sleeves too, for when we transition out of the weighted sleeves. The fabric is also really soft and nice!
