  • It really works like magic and saved our sanity!
Size: Small (12-18lbs) Color: Lavendar
So our 2 and a half month old baby was having a really hard time transitioning from a swaddle and she had become a swaddle escape artist. No swaddle could keep her contained and most of them she could break out of in just a few minutes. We had one brand of swaddle that would hold her for a couple of hours at most before she would finally muscle her way out of during the night and wake herself up by touching her head and face and setting off her startle reflex repeatedly. We tried a few other brands "transitional" swaddles but they made things even worse because they keep the baby's arms up next to their head where she would start touching or rubbing her head and setting off her startle reflex. After a few nights of trying those other brand transitional swaddles we were all going crazy due to sleep deprivation. After seeing a video of this sleep suit on social media we decided to give it a try and it worked! The big difference here is that the suit doesn't allow the baby to easily reach up and touch their head while sleeping. The thickness and stiffness of the sleeves naturally keeps their arms comfortably down and away from their heads. The very first time we put her in this and put her to bed and she stayed asleep for almost 6 hours straight which is a massive improvement! Now she sleeps like a rock almost every night. I will admit the sizing is a little weird. Our daughter is about 35th percentile in size for her age. The instructions say a proper fit means both hands and feet are visible. Her arms fit just fine in the sleeves and she could not pull them back though but her feet and legs just weren't long enough to fit into the leg portion of the swaddle and if we were to keep waiting for her to grow big enough then it would probably be another 2 months before her legs were long enough and our sanity wasn't going to make it that long. So for now she keeps her legs up inside the body portion of the swaddle so it's kind of like a sleep sack for now until she grows into it more which means we will just get more mileage out this in the long run. The material is thick but remember babies lose most of their heat through their heads and if you put them in a sleeveless/legless onesie then they will stay at a comfortable temperature all night and we have checked on her multiple times during the night or when she naps to see if she was getting hot and she never did. ... show more

  • Truly Magical🪄
Size: Large (18-21lbs) Color: Blue
THE BEST. Our baby started rolling early, so we knew we couldn’t swaddle him anymore. He had the moro reflex very strong, so putting him in a normal sleep sack to sleep was not the answer. We heard about this magical sleep suit & it really is magical! Our baby sleeps so well in it & it makes him all cozy and relaxed during him sleep! Well worth the money!! ... show more

  • Magic Indeed!
Size: Large (18-21lbs) Color: Blue
My childhood best friend gifted my grandson with his first magic sleepsuits. For him, they have been quite magical. He instantly relaxes and gets comfortable for sleep as soon as he's zipped up!

  • Great quality and helps baby sleep better
Size: Large (18-21lbs) Color: Blue
This sleep sack is really well made. The fabric is soft and breathable, and it gives my baby just the right amount of warmth. Since we started using it, she has been sleeping much longer stretches at night. It has made bedtime so much easier for us. Highly recommend to other parents!

  • for parents of a 5+ month old
Size: Large (18-21lbs) Color: Cream
This is literally the first review I’ve ever left on an Amazon purchase but I thought it was necessary because I was looking for a review like this when I was shopping and it was hard to find. My daughter just turned five months old and has been swaddled since she was six weeks old (& the first night I ever swaddled her was the first time she ever slept through the night & has been sleeping the night ever since) I was terrified of the idea of having to transition out of swaddling but knew the day would come. When she turned four months old she started getting the strength to bring her arms up through the halo sleep sack into her face waking herself up/scratching herself/putting her hands in her mouth which made her start babbling away at wee hours of the night. I decided to try swaddling with one arm out to see how it would go and occasionally it would work but most of the time she would wake up in less than an hour from touching her face with the free hand. So I continued to wrap her in the halo sleep sack, but just did it tighter than ever..& it kept working..till it didnt. She would fall asleep great but would move her arms up after an hour or so & would get frustrated trying to free her arms (even started arching her back which mad her roll to her side..I knew it was getting too dangerous to keep it up. I purchased things like the “love to dream sleep sack”, the “woombie”, & the “nested bean zen sack.” (all of which i heard great things about)..but they didnt work for her. The love to dream sleep sack allowed her to have her hands up which she had never slept like before so she was flapping like crazy trying to escape it. The woombie was good for a couple nights but she woke up to the fact that she could bring her hands up to her chest freely but then not extend her arms so she was constantly crying out of frustration. The nested bean zen sack was supposed to mimic “touch” by having a weight on the chest but the weight is light as a feather so it was like she wasnt in a sack at all. I didnt know what to do. I decided to search the web ONE MORE TIME & came across this “magic suit” ..yea ok I bet it wont work for her..but I bought it & decided to try it out. When it came in the mail yesterday I thought it looked rediculous...but that’s what all the other reviews had said..and even though it looked ridiculous..it still somehow did the trick. So when it was time for her nap I gave it a shot. IT WORKED! She slept and hour & 1/2..which she never does for a nap! (she’ll only sleep that long being held or on my husbands chest!) * I also feel that it’s important to mention that prior to trying this out we would always wrap her up in the halo sleep sack first and then rock her to sleep in our arms or on our knees on the Boppy pillow- and she would always already be asleep before I transferred her to the crib. So I knew that that with this suit I had to kill two birds with one stone: not only transition her out of the swaddle, but also have her fall sleep on her own in the crib. I waited until she was already tired, even fussing a bit..put her in the suit while it was lying in the crib, and walked away. She started crying ( naturally because this was the first time she was ever awake in her crib without a swaddle) I reassured her after 2 minutes of crying & 2 minutes later..she was asleep! On her own! Without a swaddle! Arms free to move about! I thought maybe it was just a fluke and it was just because she was so tired..so I knew the real test would be at night. Here I am at 7am writing this review..while shes still ASLEEP! We put her to bed at 9pm (going to try earlier tonight) & shes still out. She usually wakes up at 6 or 6:30. I’ll be honest I did have to go in her room and put her pacifier back in her mouth around 5 AM because she was moaning in her sleep, but I think she was just having a bad dream, I don’t think it has anything to do with the suit. I also watched her several times on the monitor throughout the late-night hours bring her hands to her face to rub her eyes..but her arms always settle back down slowly and she fell back asleep. That would not have been possible with traditional swaddles or with having her arms completely free with armless sleep sacks. I would say give it a try even if you’re skeptical that your baby is already older and even if you tried other things and they have failed…ESPECIALLY if that’s the case, try this suit out ! ... show more

I owned a daycare for over 25 years and these were the most reliably comfortable, warm and soothing sleep suits.
