### ⭐⭐⭐⭐⭐ Worth every penny
*by C***. on March 6, 2025*

I’m usually a skeptical tight wad when it comes to things like this. However I desperately jumped on the band wagon. My 3 month old has not done well with transitioning out of a swaddle and giving up the bassinet with in the same week. Sleep has been scarce. He’s always waken up every 3-4 hours but when I had to take the swaddle away it dwindled down to 2-3 hours and then introducing the crib he was waking every hour. The first night of using the suit he slept a 4 hour stretch right out of the gate and woke up for a diaper change and immediately fell back to sleep after nursing. Last night he just about slept through the night he woke up at 3 am for a quick bottle and diaper change and slept until 9:15. Now he’s not sleeping 8-10 hour stretches but I’ve noticed a difference between using it and not using it. Our second night in it he peed through his diaper at 2 am and I had to take him out of it. He woke up every hour after that. So if you’re exhausted and desperate I definitely recommend shelling out the cash. It is totally worth it. It’s great quality. Easy to do diaper changes especially with the double zipper. Feels durable with great stretchiness but not to heavy. And I went with the larger size and my 14 pound baby fits perfectly in it.

### ⭐⭐⭐⭐⭐ 5 month old’s mama believes in magic
*by J***Z on July 9, 2022*

I read the top “most helpful” review here and it sounded just like my son. So I’ll provide background for parents who are looking through these comments to see whether it would actually work for their baby.My son loved to be swaddled and had been swaddled for 4 months straight. He was a great sleeper, sleeping some nights 9-10 hours straight at a very young age. It was never always 9-10 hours but we would get those nights a lot. At the start of the fourth month we noticed he would start to get angry and frustrated that he couldn’t get his arms out of his swaddles. Sometimes he would succeed and wiggling his arms out and immediately would pull them to his face and rub or scratch his face and wake up crying or as soon as he started falling asleep his arm falling to his side would wake him up. We couldn’t swaddle him much longer because he was getting so big and starting to attempt to arch his back and almost turn on his side out of his frustration to get his arms out.At the end of month 4, we started to do the one arm in one arm one method and it didn’t really work for us. He would usually sleep one 5-6 hour stretch. Again, he’d be angry he had one arm swaddled and would fixate on trying to get it out and get angry he couldn’t. We then tried going cold turkey for a week and we were miserable. It felt like the newborn days again, constant crying and waking every 2-3 hours. I desperately looked online for a solution because we 1) couldn’t swaddle his arms down anymore 2) couldn’t leave his arms out or he’d scratch a and rub his face and wake up or his arm falling to his side would wake him up 3) we couldn’t have his arms able to freely move within (arms up position) because he have never slept like that before and hated it and criedI found this sleep suit and that comment and saw all the similarities and I ordered it after 3 nights of constant 2-3 hour wakings and the brink of insanity. When I received it and put it in him obviously he looked adorable but yes my son runs hot and I had read all the concerns about overheating. We keep our house cold year round so we decided to go a few degrees colder and set the temp (it’s June) to 68°. I put socks on his feet to keep his feet warm, only put on a undershirt onsie for him and tried it out.I couldn’t believe it! HE SLEPT 10 HOURS. I could not believe it I definitely thought it wa as one night fluke. He did awake twice during the night and cried but as soon as I would walk over to the kitchen grab his bottle and come back ( about 2 minutes) he’d be fast asleep again. I also felt him in the morning when I woke up, his body was not overly hot, it felt like a nice warm temperature along with his feet. His hands were freezing though but I had read maybe it’s okay? This morning as I write this is night #2 - the true test in my opinion. I put him to bed at 9:30 and it’s 7:45 now and he’s still sleeping. So yes, I do believe in magic lol. I’m so grateful for this suit. We needed sleep and he did too. Even if your baby is bigger (5 months) just try it out! But please make sure to keep your house cold for hot little ones!
