My baby boy kept breaking out of the halo swaddle and just overall seemed uncomfortable in it. I bought a few of the highest rated swaddles on here to see if he liked any of them. This one was delivered first and we loved it so much I didn’t even try the others. The arm band is great and he hasn’t struggled against it or broken out (we’re on night 2). When zipped up, it hugs him just right and he falls asleep almost on his own. It’s been a lifesaver since I couldn’t put him down before without him waking up and freaking out. For reference, my baby is almost 2 months old and a chunky +/- 12 lbsThis swaddle is the holy grail! I tried Halo and the Amazing Baby Transitional swaddles first and they did not help my baby sleep better at all. The Velcro wrap on the halo is way too long and my baby always managed to get her arms up and out of the swaddle. Then she would scratch her face and startle, which disturbed her sleep. With the amazing baby swaddle, she would just be flailing. It did very little to reduce her restlessness and startling. The Happiest Baby swaddle allows me to swaddle my baby quickly and with ease. Even when she becomes restless and transitions through sleep cycles, she is able to stay asleep. The only time she wakes up is if the neighbors make loud noises (ugh), she has a blowout or leaky diaper or she’s hungry. If all of these needs are meant, she can sleep for up to four hours. One time I even had to wake her up to make sure she ate, which never happens! The only time I don’t use the swaddle is at night because my baby was really hyper any time I took her out to breastfeed and change her diaper; however, the swaddle is an essential part of her nap routine.This swaddle is so so great if you have a baby that is a houdini at getting out of swaddles or if your swaddling skills are sub par(like me)! I highly recommend getting this as it's super easy to use and my son couldn't wiggle his way free at all thus keeping him tight and cozy!We tried different swaddles (Halo, love to dream) but my son was able to get his hands out of the swaddle and that would wake him up. He was also uncomfortable in those. After some research I tried this swaddle. So far it has worked the best for us. He was able to get his hands out once or twice when we swaddled him little loose but that didn't wake him up. Very easy to swaddle as the name says 5 second swaddle (specially after night feeds). He slept for straight 6 hours. ?This is the best swaddle out there. It’s got mesh which helps keep my baby cool because she sleeps really hot. It seems really well designed and made. But most importantly it is the only swaddle my baby couldn’t break out ofWe recently have gone through 6 different swaddles for our third baby. I thought I knew all of the tips and tricks but our third little one has a different idea of comfort and is a miniature Houdini! She was able to get out of the Halo sacks, hated the love to dream, and woombie swaddles, but loves this one! She slept all night long in it and it never rode up to her face! I feel like this swaddle is much safer and helped keep her a lot cooler than other swaddles as well. This swaddle is a game changer!!Already came to leave a review after just 1 use. I am so excited about this item after using it last night! I have gone through quite a few swaddles before finally finding this one and it is far superior to the others. My son was fussy and tired when I put it on him and it immediately calmed him and he fell right to sleep. He normally wakes to eat at midnight and 3-4am but we've been trying to stretch those windows and last night he woke at 1am and 6am- the first time to ever go that long! His arms stayed in place that entire time too. The only thing that is a little more difficult in this one compared to other swaddles is diaper changes bc you have to unvelcrow the part over the diaper which is a little loud. A few comparisons to the Halo sleep sack swaddle- the flaps are much shorter- gave me the ability to do a much snugger swaddle where with halo the flaps are super long and you have to get it way behind baby and even still for us was never a super tight swaddle + would ride up towards his face and his arms would get out. I cannot believe how much better this held his arms in!Best swaddle we have tried and we tried a million. Best to wear a onesie with it if your baby doesn't sleep in AC or a light PJ if they do. My baby slept through the night by 6 weeks or so. I can't say it was the swaddle but I can say it's worth a shot.This sleep sack has the right idea. It’s definitely made small, but I assume that’s the point of it. However, the inner Velcro is really not needed and very loud for middle of night wake ups. I wish it was removable because I think it would work just fine zipped up because it’s already snug. Other than that, my 8 week old has been sleeping longer hours since, not sure if it’s a coincidence but I think it has helped!Le mie fasciature, quelle con la coperta per intenderci, tendono a slegarsi. Siccome la fasciatura permette a mia figlia di dormire più a lungo e soprattutto di calmarsi in brevissimo tempo, ho cercato un'alternativa. Questo é in pratica un sacco nanna con all'interno tre lembi per legare la bimba o il bimbo. Quando non ci sarà più l'esigienza di bloccargli le braccia lungo il corpo (scopo dei due lembi superiori), ci sono dei bottoni per farle uscire e quindi diventerà un normale sacco nanna. Per questo motivo, e per i buoni materiali/finiture del babywrap, il rapporto qualità prezzo é soddisfacente. 4 stelle perché il braccio destro della bimba si libera facilmente, come già rilevato da un altro utente, e perché la parte dove aderisce il velcro si spelacchia in men che non si dica. Nonostante sia leggero (il cotone é molto morbido), la bimba sta calda per via della fasciatura e la devo lasciare a maniche corte. Non so se sia dunque utilizzabile tutto l'anno. Volendo si può cambiare il pupo senza toglierlo dal sacco e addirittura senza slegargli le braccia perché ha la cerniera che si apre anche da sotto e la parte a mutandina che si affranca ai due lembi chiusi si può facilmente aprire.To preface - every kid is different, and what works for my youngest did not work for my middle child or oldest. Keep that in mind when reading through the reviews.Pro- easy to use, and versatile. Provides your little person a hug while still allowing for free armsIf need be. Allows for climbing without bunching up around the neck. Never had this issue with swaddles before but then again, neither of my previous kids had legs ad jumpy as my little guy. Finally the neck opening allows for my little guy to suck his fingers when he wants but still prevents the startle reflex.Con - the snaps are a little rough when arms are out, so it would need to be worn with some sort of sleeve. It is also more costly than most other swaddles.Every baby accepts swaddles differently. My son loved the love to dream angel wing swaddle sack. We hadn’t been able to find the right one for our daughter. We were using the Gunamuna sleep pod but it was too heavy, though we loved the interior band design. I found this one here on Amazon and figured we’d try it since it had that interior band we liked. It’s been perfect, we love how lightweight and breathable it is, it’s easy to quickly put her into it, keeps her snug and secure, and doesn’t bunch up around her neck. We ordered the next size up since the small is definitely only for those early weeks. So this one was a 5 star perfect choice for us, hope it works for others too.I bought this as my 2 1/2 week old was not sleeping longer then 45 minutes - 1 hour at a time. I tried swaddling her with Velcro swaddles, love to dream, a blanket. Nothing seemed to work she fought her way out of everything! This swaddle is great. She doesn’t try to fight her way out and it’s easy to make snug. Less then 5 seconds and she’s swaddled perfectly. I can set her in her crib half awake and she will settle and go to sleep. Now she’s sleeping 2-3.5 hour increments!! Highly recommend!!!
