Total game changer! She loves her hands up, so this sleep suit enabled that while keeping her tight and cozy! She now sleeps 6 hours straight at night...and she’s just 6 weeks! I already went to buy the 3-6 month version and was so sad it’s sold out. It gets restocked soon!

This is the face of a baby that absolutely LOVES this swaddle, and believe me....we have bought them all! She was born at 5lbs 12 oz, so she’s always been a little on the smaller side, so the 0-3 has been absolutely perfect for her! As soon as the 3-6 is back in stock we are getting 2 since she’s now outgrown the current length of this size. I love this swaddle, it’s superior in every area!

I started off with just regular swaddles, and they worked okay. Then I came across nested bean and got 2 of the den classics. Little man eventually got big enough to break through them so I wanted patiently for the Zen One transition swaddle. These products have done wonders for us. Baby sleeps throughout the night, and if he does wake up it's only once and right back to sleep! I swear by these products and tell ALL my mom friends about them

Our little guy loves the Zen One. He is sleeping at least 2 hours longer! Anywhere from 7-10 hours each night, then more after an early morning feeding. Used the sleeves the first week then he began getting frustrated & waking up so we removed them. We don’t use the Velcro band. He is 3.5 months & almost 15 pounds—wish it came in a larger size! We did purchase the sleep sack to grow into, but that one is not tight around the middle.

Honestly, we were very excited for this sleep sack as we had heard others have success. However, once we tried it out for a few nights with our little one we were not impressed. It’s a fine product but for our little girl it performs just as well as other lower priced products (i.e. sleep swaddle sacks). Unfortunately I would not purchase again, was hoping it would be the ticket for our little night owl but it turned out not to be the case.

I did not notice a huge difference it it helping my son to sleep longer. He only wore it a few times and the zipper was kind of in his face because of the design of it. I couldn't zipper it all the way up and had to tuck it under so it didn't bother his chin. He doesn't swaddle his arms so the part that wrapped around his body wasn't needed. I will try it a few more times but he is sleeping longer just on his own with his own development. He is now 3.5 months old.

I can’t wait to for my newborn to get here and try it out.

I thought my daughter would love this since she likes sleeping with her hands above her head. I waited weeks for it to come back in stock and finally got it when she was about 6 weeks. I bought both the 0-3 and 3-6 sizes. Being 6 weeks and about 10lbs I figured she'd fit in the 0-3 just fine. But she was just about too long for it. The arm holes were hard to fit her arms in, they're really tight. And when I took it off her she had the mesh imprinted on her knuckles because it was too tight. I continued to use it for several days. Several times during each day for naps. And she just fought me every time she didn't like it. I did also try the 3-6 month. But it was a little too big and was too much material around her neck and mouth. I'm still going to try the bigger size within the next week or so. I'm disappointed she doesn't like it so far, I really wanted her to. I think I'm going to end up returning both sizes.

We love the zen swaddles. We initially ordered the zen one in 0-3 months for our newborn and it was quite small, and only fit her for a week or so. But we immediately ordered a new one because we could already see a huge difference in our daughter's sleeping habits. She went from sleeping about 45 minutes at a time, to 3 hours, and kept increasing. She likes having her hands up so the hand attachments are genius for keeping hands up, yet in place so baby doesn't startle themselves. Basically this product has been a lifesaver for us . Also--- we were still able to return that first swaddle even though the return window had closed thanks to covid. AND after we returned it, I received an email thanking me for the return and saying that it will be donated. I really appreciate that returned swaddles are donated. So..we are impressed all around! With the products and the customer service.

It is extremely tight for our chunky guy and it unfortunately didn't improve his sleep :(

My daughter has been sleeping in this sack since she was 9 weeks. She used the Nested Bean swaddle before that. I do find that these products work great. She has been sleeping peacefully for 6 hours at night without stirring. The one thing I don’t like is the tightness of the sack. My baby is 12 weeks now and weights 12 lbs, the sack is a little tight which I do realize is half the point of them but I don’t find where she will be able to still use it up to 18lbs as it states. I wish they made one one more size up. She hasn’t graduated to the arms free yet. But she and I love it all the same. It will be a great sleep sack when she has arms free also.

Before making this purchase for my 4 month old, he would wake up every three hours for various reasons BUT now he honestly sleeps seven hours straight! He’s so comfortable in his sleep and wakes up with lot of energy. Love this product

My daughter was breaking out of the swaddle and waking up every 2 hours but with this sleeper she’s doing much better sleeping and has done 8 + hours at a time.

I only wish I could’ve gotten it sooner! They were on back order, so my little was almost 3 months before we started using it... but it’s wonderful! She’s been a swaddle baby from the start, I would get her as tight as possible but as she got bigger and stronger she was breaking loose from the swaddle with the blanket! Now, she’s in her Zen One nice and tight and is sleeping for 10-12 hours every single night. She’s not even 4 months old! This momma is happy!

Such a great product! We have used the swaddle and now the zen one and we could not be more pleased. Our little one started sleeping through the night as soon as we introduced Nested Bean products.

Amazing product she seems to really like it

My baby loves to have her hands up. She only wakes up once for a feeding now which is a huge improvement. She will be 3 months next week! I want to get a second one but they are sold out currently!

Our little one loves it!! I love that her arms are able to be up by her head but still contained enough not to wake herself up. Well worth the money!

I read all the reviews and really did my homework before making this purchase. The reviews were fantastic and we are right in the midst of the 4 month sleep regression/transition out of the traditional swaddle. Maybe it was all the changes (?) but it hasn’t been our saving grace. I do like that we can unzip the sleeves when he starts rolling back to belly.

I purchased this after seeing so many ads about getting better sleep within 1-3 nights. It has not lived up to that and I've had it for 2 weeks. My 4 months old sleeps no differently than she did before this. Its a nice design and I really wanted to like it but it just turned out to be another waste of my money.

Fist nap using the swaddle was over 2 hours!!! A week later and my 5 week old is giving me 4-5 hour stretches at night and will even put himself to sleep!!!! My only regret is that i waited so long to purchase it!

Love it! Baby falls asleep on her own! She outgrew newborn swaddles, and this was the perfect transition.

My son loves to be swaddled but hated his hands being restricted to his sides. We got the Zen One because his arms could be up while being swaddled, but wasn't able to claw at his face when he gets tired. The weighted sleep sack has helped get him to sleep faster and allowed him and US to get longer stretches of sleep! Definitely recommend! -Danielle

I really wish this item came in a third size that was larger. It seems like a perfect combination for our family because sometimes my son prefers to be swaddled hands down and sometimes he prefers hands up and to the side of his face. I also like that the hands zip off so it could be worn after he starts rolling over. However... at 2 and a half months he has already outgrown this item. He was large for his age (95% percentile) at his 2 month appointment, but he has not hit 18 lbs yet (he was 15 lbs 2 weeks ago so he's maybe 16-17lbs right now). Yet we can't even zip up this item it's so tight. Since this item has arms that zip off to accommodate babies that roll having a larger size would be much appreciated. As it stands I spent $50 on something that should work for my baby's weight that literally would not zip up the first time we tried it.

I really wanted to like this swaddle and how versatile it is. My 4.5 month old is at the max weight so it’s pretty tight. It’s too bad this isn’t available in a larger size.

My daughter is 11 weeks old. The first night she wore it she slept 7 hours straight! It was a dream come true! I love this thing so much! One of the best baby products I’ve purchased. I bought the 3-6 so it would last her as long as possible without having to purchase another one.

So far we have really enjoyed the Zen One sack. My only complaint is that the sack is not very long. My daughter is 4 months old and is nearly too long for her 3-6 month sack, and she is average in weight and length. Wish they had made it longer!

So far, so good! We are definitely starting to get 4 hour stretches with the help of the swaddle at night-- however, I am still hoping it will help with naps and it isn't just yet, but I am hopeful!

Was waiting for the Zen One to be restocked and once it did, I grabbed one right away because my oldest loved the swaddle but my newborn, an escape artist... long story short, my newborn will be 3 month in a couple of weeks, I ordered the 3-6 months— and it’s already too small for him. I believe it shrunk while I washed it? I don’t know but spending $40 for 2 weeks of usage is pretty wasteful, I wish they come in larger sizes for parents to choose from. No, my baby is not a large baby, born 7lbs 10oz. Has the sleeping improved? Ahhhh... it’s not a magic swaddle as some of the videos may have shown.

Worked wonders for my LO. We started using it when she was 6 weeks old and she slept 2-3 hours longer that first night and has ever since!

Love the fabric and quality! However the sizing run small, our 11 week old is pretty snug in the 3-6month size. He will soon out grow it, especially the zipped arm pockets and the space under his arm pits are already tight

I absolutely love the zen one. We started with the zen swaddle and my daughter started sleeping through the night the first night we put her in it at 2 months old. We transferred her to the zen one just recently and moved her to her crib and she is doing great! As soon as we zip her up she starts to close her eyes! Life saver!

My third purchase from nested bean! My daughter sleeps SO well since we started using these products when she was a few days old. I’ve since bought two more to give as gifts.

My baby sleeps through the night with her nested bean. Worth every penny.

Get this!!!! You will not regret it! We went through two other sleep sacks before trying this one and at 6 weeks old we put my daughter in this and I kid you not she has slept through the night ever since. She is now 4 months and we just got her the next size up in the ZEN One. Love it!

Love! Love! Love! The ZEN One is a life changer!!! My baby has been using one since about 6 weeks old and sleeps soundly all through the night! Can't recommend this one enough!

Couldn’t wait for this product to come off of back order and as soon as it did, I ordered ! He slept through the night the very first time we put him in it and has continued to sleep through the night !!! We love our nested bean!!

I had such high hopes for this product but I haven’t seen any improvements in my son’s sleep yet after one week of use. He is still waking up all night. Also, I was really surprised at how small it is. My son just turned three months old and I purchased the 3 to 6 months size. It’s already extremely tight on him and I don’t see this lasting him much longer. He is on the taller side, 75th percentile, but still I am a little disappointed that it definitely won’t last him through six months.

Baby loves this and is sleeping so much better!!! Wanted to order another on but said "Out of Stock"!!!

My daughter is 3 months old. The first night my daughter slept well, but she still woke up for one bottle during the night. By the second night she slept through the night 10pm-9am! She is still very young so I very much believe the Zen One sack helped her soothe herself back to sleep. Was worth every penny.

I liked the concept of it, however it is not for chunky babies. I bought 3-6 months as it was the biggest size and o couldn’t stop her arms in bc it was too tight. Also in general it was still tight. Mind you she is not a massive baby either so disappointed that I spend $50 for it not to fit her. I couldn’t refine it bc I had washed it before I even put it in her.

My baby girl is 7 weeks and I have struggled getting her to sleep in her bassinet/crib. I received the Zen One yesterday and first night was a SUCCESSS!!! . I could not believe it! I tried all type of swaddles and tricks and nothing was working . Thank you!!

Love!! We started with the Nested Bean swaddle, but my little girl hates her arms being contained. She has slept with her hands above her head since she was born. (She even wiggled an arm out of her swaddle in the hospital!) The swaddle helped her stay asleep all night since day 10 of her life! When we switched to this one, she was much easier to get to sleep, and she stays asleep. She can chew on her fingers through the mesh if she wants, and she loves that. I will absolutely be using this for each baby, and it is my new baby shower gift!!

Definitely a must have for first time parents. Our son went from sleeping 3-4 hour stretches to sleeping nearly 6 hours straight every night!

I love that even with the sleeves attached, Luca is still able to suck on his hands (or at least try). As he is discovering his hands and learning to self-soothe, he can still do this and get back to restful sleep while wearing the ZenOne sleepsack!

I had a basic swaddle. And I thought this was gonna help since she was out growing the other swaddle and it Just made it worse I think. She went from waking up once a night at 5am to waking up 4 times. I don’t think this swaddle is for her

She sleep so amazing with the sleep sac on! So happy with our purchase!

I ordered this swaddle at 4am while feeding my little one. He seemed to always be fussy after a middle of the night feeding when I put him in other swaddles. He didn’t love the Ollie swaddle or the Halo and prefers his arms/hands up and next to his face so I thought this one was perfect. I put this on him and he calms down what seems almost immediately. It’s magic and very well made! I already bought the 3-6 month one for when he outgrows the 0-3 month size. If you are on the fence get this one!

We purchased the Nested Bean Zen One right in time for our baby's 3 month birthday. Our baby is average in weight and height and we found that the sleepsack is actually really snug around her chest and belly. I don't see how they will be able to wear this for the next couple months until they turn 6 months old. We have tried it for 7 nights and have seen slight improvement in sleep. Our baby has not been consistent with sleeping a certain number of hours per night. It typically ranges from 3 to 4 hours which was similar to how they were sleeping prior to using the Zen One. We will continue to try it out but this seems like a one-time purchase for us.

Absolutely love it. Makes naptime and bedtime so much easier.

I was counting down the days until this arrived! Our little girl at 4 weeks decided she hated the swaddle and wanted her arms by her face. I ordered this in a hurry hoping that it would help at night. Guess what? It did!! She's now going in 4 hour stretches whereas before it was closer to 2 to 3 hr stretches. It doesn't matter if you're a first time parent or a seasoned parent (this is our 3rd child), I would recommend everyone buy this!

Honestly I have not really seen much of a difference in my son's sleep. I was hoping it would help soothe him when he begins to toss and turn in the middle of the night, but he remains the same.

this product is excellent!

Absolutely love this product! I have been waiting patiently for it to come back in stock since my baby was born and now he’s 2 months old. He sleeps great now and loves being able to have his hands near his face. My only complaint is the size. I ordered the 3-6 month and I don’t see this fitting my baby for much longer. He is on the bigger side but not even 3 months yet. Wish there was a larger option.

My son loves it! He was a pretty good sleeper before but now even better! He loves it! I just wish it came longer in length. He’s not even 3 months old and in the 3-6 month size. I’m not sure he’ll be able to use it for even another month or so.

LOVE LOVE LOVE!! I can not say enough about the Zen One!! My baby is 8 weeks old and puts herself to sleep with this on. She hated being swaddled because she didn’t like her arms being restricted. With the Zen One she can have her arms up but they’re secure enough that she doesn’t wake herself up. I will be purchasing the larger size when she grows out of this one. If you’re on the fence about this, just DO IT! It’s the best money I’ve spent!!

Love this! It looks really cute on our baby girl. She started wanting to sleep with her hands up but would wake herself up in a regular swaddle overnight working her hands out. Now she is able to put those hands up and sleep through the night at less than 3 months.

Bought as a gift for my next future grandchild. Some of my other grands have them and they sleep so much more peacefully.

Our little never liked having her arms swaddles by her side but her startle reflex was really bad. This swaddle was a game changer. She loves that she can self sooth and we love that we can take the arm pieces off., Also the fabric is always cool to the touch. Thank you!

Seems pretty tight when I use the inner swaddle part for his arms- it’s hard to dip up over his arms/hands while in the inner band. He’s not at the limit weight or height either.

I like the product but I just noticed the beads have spread throughout the top of the swaddle and not just where the egg is. I don’t think that should have happened?

I got this swaddle because my baby was never a huge fan of having his hands pinned down when swaddled...this option worked like a charm, he goes down soooo much easier with this on and it also helps re-settle him (he is a super active sleeper and wakes himself up constantly)- at 8 weeks I started getting 7-8 hrs stretches from him which is amazing. I give it four stars because, I agree with a lot of the mothers on here, the sizing isn’t great. He hit the max weight for the newborn size within a week and a half after we started using it- he is ten weeks now and we are still using it because it still zips, but we will have stop soon and- at his rate of weight gain, he will likely outgrow the next size up soon after it’s available again so we will have to just switch to the sack, which I’m not too excited about because it won’t really provide the swaddle effect that we’re looking for.

I really love this swaddle and how versatile it is! You can pin the arms down, zip up with the arms loose, put the arms in the little caps, or unzip one or both cap sleeves. My one complaint is I wish it were longer. My son is very tall and won't be able to use this much longer. He is three months old and is wearing size 3-6.

I love it

Our baby first used this close after a week old. Now 6 weeks old and it’s already a bit tight. For the price, it doesn’t get much use. Wish I got the bigger size but our baby seems to prefer the zen sack better.

Absolutely in love ! Within one week my baby girl went from 3 hour sleeps to a whole 8hr sleep . She’s down by 9pm and won’t wake back up till 6am!!! The best purchase any mom can make

My little guy loves this because he can have his arms out but is still all snuggled up!

My little guy was only sleeping 2-3hr stretches at a time before the Zen One. At 2.5 months old, I was desperate to try to find a way for him to sleep better before I returned to work. I purchased this, and within a week, my guy was sleeping 7+hr stretches! He absolutely loves it; he smiles every time I put it on him. Only wish I would have bought the 3-6mo one as well!

I am absolutely loving this sleepsack! Our sweet girl has been sleeping through the night and I am so ordering the next size up! The only regret I have is not getting this with my other little ones when they were babies. This is a must for every mama!

I like the design but sizing was off so my child has never used it. In the middle of a pandemic so returning isn’t possible. My child is still in newborn clothes and only 8 pounds but the zen one 0 to 3 months doesn’t fit. He needs his arms inside for it to beneficial and it won’t zip up with his arms inside.

The sleep sack seems to work very well (baby sleeping from 7:30pm to 5:30am!) but unfortunately it also seems to run very small. I ordered the 3-6 months sack, hoping to get several months out of it, and my 2.5 month old is almost too small for it. I’m sad that the sizing is way off and we will only get to use it for a few weeks.

This settles my baby boy right down and helps him stay asleep!!

I love the design behind this sleep sack; however the sizing seems to run small. My child is 4.5 months old and in the 50% range for weight and height and the sack seems to be too snug - especially in the mesh arm compartments.

Amazing it help my clingy son to fall sleep

My baby would wake up as soon as we put her down, now she wakes up a bit. We rock her in her bassinet and she's out. Stays asleep all night!

We love the Nested Bean product line, but for our baby the Zen One wasn't our favorite. I found my self just using the NB swaddle instead. Zen one was tight on her and kept riding up, seemed uncomfortable. She did use the zipper sleeve feature for a couple weeks but grew out of the need for it quickly. Looking forward to moving into the sleep sack.

My baby was within the weight and heigh ranges recommended, however it seemed very tight on him. Therefore I only used it twice.

I bought it because it allowed more freedom in the arms. I ended up taking the arm covers off right away because they were small and she still felt restricted. The suit is also very snug which is great for now but she will grow out of it fast. Overall though she has improved her sleep!

Love it

We got this at the perfect time! Our little boy has been sleeping 8+ hours a night (in one stretch) since just before 2 months thanks to the zen swaddle. Right after we got this one he started rolling over! We were able to go directly from arms in swaddled to arms out and it didn’t disrupt his sleep pattern! Love it!!

The first couple weeks every time we put him in his bassinet he would wake up and want to be held. We got this when he was 3 weeks and the first two nights it took some getting g use to now once we’re ready for bed we put him in it and he soothes hisself and goes right to sleep. Love it!

Love this zen sleeper! My 5 week old wouldn’t sleep at night so we were desperate for anything and the first night she wore this she slept for hours! It’s been a life saver. She sleeps in it every night!

We have both of the zen one and zen sack premier and love them both. Unfortunately, I made the mistake of drying the zen one on medium heat in the dryer and it shrunk quite a bit-which is my own sleep deprived mistake and my son is pretty long so the amount of usage I get out of that one is hard to tell . But both are great quality and he loves sleeping in them

I purchase it for a baby shower gift for my son & his wife. They loved it! Her due date is in June and I'm just hoping that he will be at a good weight to fit in it.

Wish it was a little bigger length wise. My son is 11 bs but 24.5 inches so i was only able to have him wear it for a couple weeks. It’s a little too tight for him now

My nephew has been loving this since the day it came in! Sleeps like a baby! My sister loves it!

My daughter is 3 months and a decent sleeper. She wakes once or twice overnight to feed but otherwise sleeps 7pm-7am. The first night she screamed when I put the Zen Sack on her. Not sure if it was the swaddle or just her witching hour. She was already used to wearing a swaddle with her hands up, so the weight was the only difference. She did better with it during naps the next day and was fine when I put it on her the next night. I haven’t really noticed a big difference with her sleep though. I was hoping it would help her fall asleep more quickly, especially at nap times. But she still takes a while to fall asleep and often needs soothing from me. In summary, the Zen Sack is fine and works as well for her as similar swaddles without weight, but it’s not a miracle worker for us.

It's a good quality product using good materials. My son likes it just as much as his old swaddle sack and I didn't see any difference in his sleep (all the claims about longer, better sleep), but I'm okay with that because he sleeps well for the most part. HOWEVER, two things bug me about this product: 1) there is nothing separating the zipper from his skin. As such, he always needs to wear a full onesie when in the product or it would be uncomfortable/irritating for him. 2) the sizing is all wrong. It says starting at 12.5 pounds and my son is only twelve pounds (two months old) and can BARELY FIT if we use it as a swaddle with this arms strapped. This product will definitely not last all that long for us, even if we graduate him early to having his arms out of the sleep sack. It's also quite short for a sleep sack that is marketed for 3-6 months. This is really dissapointing considering the price we payed. I was considering buying his sleep sack from Nested Bean as well, but I'm now hesitating to.

Once we started using our nested bean bedtime got a lot easier. Our son started falling asleep quicker and stayed asleep for longer.

This thing is the best. I was just putting my baby down and thinking how grateful I am to have this. I pretty much only put him down in this because I’m guaranteed a better sleep than if not. Worth the buy!

Our baby girl prefers to suck on her fist at night, so traditional swaddles were not working well. We tried leaving an arm out but she'd hit and scratch herself accidentally. She loves that she can still get her fist in her mouth, but she also feels secure. I was also worried that the Nanit breathing band might be interrupted by the 'beans' but it works perfectly! I couldn't find a reviewer online that stated this, so if you are a Nanit breathing band user, rest assured, it works :)

Phenomenal! She has been sleeping nearly on time every night for multiple hours. This sleep sack really made all the difference and she’s just a little over one month old. Thank you!

We love our nested bean! It’s not a complete miracle worker, I don’t think one of those exists, but it’s pretty amazing. Our one month old began giving us a consistent 5 hour stretch of sleep at night within days of beginning to use the nested bean. He’s not a very great napper, usually only sleeping for sporadic 30 minute stretches unless he’s sleeping in our arms. With the nested bean we can usually get a 1-2 hour nap in! We’ll definitely be purchasing the next size up.

I love this and will be ordering the Zen Sack when my little outgrows the Zen One! The baby had trouble settling in the bassinet and was in a co-sleeper in our bed for the first few weeks... and we wanted to get them in the bassinet sooner than later! This baby doesn’t like being swaddled, but would move their arms everywhere and wake themselves up. I was a little hesitant about the arms, but after a night or two it worked like a dream! Baby is now 2 months old and sleeping between 6-8 hours a night. If your baby weighs at least 10lb it there about, definitely order the 3-6 month size. It seems to run small!

We really love our Nested Bean Zen One. Our baby, Callum, was a pretty good sleeper to begin with, but we were looking for something that would assist in the transition out of the swaddle when the time came. I loved the idea of the gentle weight, as Cal is always comforted by our hand on his chest at night, and we thought he would like the ability to have his hands--though contained--up by his face. We tried a small size when Cal was about 7 weeks old and sleeping 6-7 hours. My recommendation: this product is so versatile, don't be discouraged if one use doesn't seem to work - keep trying! We first had him in the sack with his hands contained in the little wings, up by his face. The first night was amazing - he fell asleep instantly and slept probably an additional hour, and much more restfully. However, after that first night, he started to struggle more and more, and eventually was getting so worked up he couldn't fall asleep. So! We adjusted. We experimented a little, and eventually tried leaving one arm completely out and one arm swaddled inside the strap. In that orientation, since 8 weeks, Callum has been sleeping 8-9 hours, and since 9 weeks, he sleeps 10-12. He is also vastly more restful, eliminated his last middle-of-the-night-feeding, and isn't struggling to escape. He falls asleep quickly and is able to comfort himself by sucking on his hand. In short, great product, and don't be afraid to experiment a little if one use of the Zen One doesn't seem to work - it really has so many options, I imagine most people will be able to find one that works. We've already bought the next size up. Thanks for a great product!

We used the nested swaddle when our baby was 1 month old and he LOVED it. Once he could break out of it at 3 months, I ordered the zen one but it was not so magical. He likes sucking on his fingers now, but the fabric isn't very stretchy and he has a hard time getting his hands (when the little wings are zipped on) which then makes him cry and wake up more often. I was bummed because he went back to waking up every hour again. :( I know if won't work for everyone though. My hopes were high, but this one just didn't work for us.

I do think that this has helped our now 10 week old sleep. She still will be restless toward the last 1/3 of the night, but the beginning of the night is going really well and she was getting up even between feeds to be held back to sleep. She even seems to be self settling sometimes without crying in the night if she does wake up. I am a little disappointed though because we just started using the little “sleeves” with the mesh instead of the built-in swaddle and the zipper track on the right arm continues to come undone in the middle of the night. It is always fully zipped, but the track comes undone when she must wiggle enough which is a little frustrating since her startle reflex is still very present. We are pretty sure she wakes herself up when the right arm comes out but overall, she is sleeping better than she was prior to the purchase.

My 3 week old baby girl was becoming frustrated with the Swaddle Me. She likes her hands for self soothing but leaving out an arm would set off the startle reflex and would wake often. Not to mention having to completely unswaddle her for diaper changes with the noisy velcro! We LOVE the Zen One! Not only can she have her hands by her face, the weighted panel puts her back to sleep, she startles much less now and sleeps deeper! Ahhhh! Such a relief! She even sleeps through diaper changes! I bought the small and she is almost 11 pounds. When I have both arms down, I almost cannot zip it closed so I'm glad I sized up! I'll be buying more when she outgrows this sleeper or her needs change!

I really wanted to love this product, but it wasn't the miracle I was hoping for. All in all, it made no difference to my 4 month old's sleep, but it is good fabric and a nice design, so we've kept it. Only wish it helped him to sleep longer, but alas. Sleep regression is a strong force.

He sleeps so much more sound with this sac! Love that is interchangeable for arms down, up or out!! Will be ordering the 3-6 months in a week or 2. So happy with the product.
