Nested BeanZen Sack® Premier | Infant Sleep Sacks | Baby 0-6 M | TOG 0.3 | Bamboo Rayon+Cotton Blend | Eases Swaddle Transition | Aids Self-Regulation | 2-Way Zipper | Machine Washable

I was getting maybe 2 hours total sleep a night, 15 minutes at time when I purchased the Zen Sack for my 20 week old. My son went from sleeping occasionally through the night to waking up every hour on the hour after the 4 month sleep regression. He always slept much better in my arms, so I thought the Zen Sack would help him feel more secure as we transitioned him to the crib from the rock n' play. We had to do this transition much quicker than we would have liked since he was rolling over. We started sleep training him the same night we started using the Zen Sack, and the first night he fussed for 5 minutes initially but quickly fell asleep and slept from 8:30pm to 7am. I was shocked! We have had the product a week now and he is consistently sleeping 8 - 9 hours at a time. I can't say for sure that the Zen Sack is 100% responsible but I think it really helped him as he learned to self-soothe. Excellent product, I only wish I had found it sooner! Planning to buy a second one to have as a backup while the other is being washed.4.5 Month old, 16 lbsPurchased the 6 - 12 month size for room to grow. With double shoulder snaps, it fits great now and has plenty of room for him to grow.Soft fabric, excellent quality, washes well, and is super cute.

These things are fabulous. I first ran across them in a Facebook ad (of which I’m usually a little skeptical) but I have a 4 month old and I love sleep, so I clicked. Then I ordered. My baby was already a good sleeper, but now she reliably sleeps through the night, 6:30pm to 6:30am, 5 out of 7 nights. It’s awesome. I feel a little bad even writing it (and also afraid I’ll jinx it). But this is a great product. Soft, cozy, good for warm or cold weather (if it’s cold you’d definitely need a fleece sleeper under it), and effective. Because sleep. My only complaint is that it’s a little tougher to put on than a basic sleep sack (the ones that zip from the top down. This one has two sets of snaps and a zipper and definitely requires a bit more effort. But...at least in my house that effort translates to sleep.

I usually don’t like leaving a review so soon…(only used the product for one night so far). I received the package yesterday, washed it and used it right away.My baby will sleep/ nap in my arms all day and night but soon as I put her down.. she’s up again.Also she started rolling over at 5 weeks, so when I put her down for a nap, she immediately starts kicking and rolling over to the stomach position.So needles to say, I’ve been looking for something to help me and baby get better sleep at night.I put this thing on her and she slept for 5 hours straight!! Honestly, she would have slept long but I needed to nurse her so I woke her up. I mean 5 hours is a record for us. So after I nursed her, she went back to sleep for an additional 4 hours. After waking up for the morning, she didn’t cry, she just laid there, content… I was shocked.The little animal is placed in the perfect spot, which I think mimicked a hand. I purchased size 0-6 she has plenty of room for growth.I also like the double zipper, which allows for easy diaper changing.The material is lightweight, can easily be used in summer and winter.The item is worth the money and a great investment!

Like every product there are bad and good reviews, I've gone back and forth wether to order or not, I even went to their website to look around. After sometime thinking I decided to order this for my 5 soon to be 6 month old boy, he has struggled with swaddles so it took time to find one that would work, then moved to arms up swaddle sacks (which did help him sleep tremendously!) now with him sleeping on his tummy and moving so much it was time to move to something new. My son needs to his legs or arms some type of restraint or he will stardle himself. He has been sleeping pretty good through the night lately getting up once sometimes twice so I was a little worried moving to something just having his legs but not arms inside something would make things a little harder but he honestly had the best sleep of his 5 months of life! He even looked so comfy! Slept all night and didn't need a diaper change till morning. I wish I would have known about this company earlier they have pajamas and infant swaddles. Definitely keeping in mind for the future!

The sleep sack is amazing quality and very soft. Suitable for summer sleeping.But it doesn’t work for our baby’s.I just wished it worked for us!

My little one absolutely loves this night sack. It helps him sleep at night and during nap time. We live in the south, so it is the perfect lightweight that he does not overheat in it.

We have been using it for about 2 months now and we love it. Our baby sleeps soundly in it.

This works great for our 6 week old. He is 12.5lb and 23” long. He has tons of room to move his legs and room to grow lengthwise. The top fits great but he will probably grow out of fitting in the top in a couple of weeks. He sleeps great in it though and the 2 way zipper is amazing for middle of the night changing!

Love this sleep sack - the material is super soft, the design is adorable, and it keeps baby warm. I am not sure that the weighted element has made much of a difference, but it hasn't made his sleep worse. Worst case scenario is you have a nice new sleep sack.Cons: comically large tag sticking out.

I love the light weighted component of this. I enjoy the zipper for nighttime changes. I’m not convinced babe sleeps better with it. But the patterns are adorable and I do own more than one so I would recommend. It is the priciest sack I own.

Overall it didn’t do anything for my baby, she’s 6months and is having a hard time staying asleep for long so I thought to try this out since the reviews are mostly great! I will give it 4 stars because the sleep sack is amazing quality and very soft. The idea is great I just wished it worked for us! I would like to add we did try it for the 7 days they recommended in the original website.

It makes a really good tool to help my 2 month old sleep through the night.Calms baby.

super happy with this, and my son sleeps sooo soooo well with it.
