Hands down the best swaddle out there
This is hands down the best swaddle I have been able to find. My baby is quite an escape artist. After trying a few types of swaddles I ended up spending the money for the sleepea swaddle and it was worth it. The size S for my 3.5 month old was perfect. Material quality is really good and soft. The inner band of the swaddle is very stretchy so you can make it right without having to worry about affecting your babyâs blood circulation. The mesh keeps my baby nice and cool as she tends to overheat easily. The only thing I would caution people about is if you allow the hands to be free within the swaddle, your babyâs nails may get caught and yanked on in the mesh. So make sure their nails are filed or cut.
Great swaddle!
Great easy to use swaddle!I initially swaddled my baby with swaddle blankets but she would always break free. This one is a lot better and worth every penny! I even used it for transition out of the swaddle with leaving one arm out and then both and it worked very well.As other reviewers have said, make sure the velcro is stuck together before putting in the washing machine to protect other clothes!
We get to sleep
Highly recommended and worth the price. Before getting this, baby would cry the moment we placed her in the crib. After we got this, she slept up to 6 hours straight and wouldn’t sleep without it. We stopped using this since she started rolling and falls asleep on her own now.
Great product but made a little small
Love this product! The Velcro is very silent and the âswaddleâ is actually like a straight jacket design. Super simple to use. Unfortunately it seems to be made small and is slightly too tight on my newborn. I will be returning and purchasing the size up.
Love love love
Love everything about this swaddle. I was on the hunt for some thing I could feel comfortable leaving my newborn in without overheating in the summer months she loves the swaddle and slept for hours the first time using it
It fits smaller than the sizing I was expecting
The material and how itâs made is good quality but I find itâs a smaller fit than I like and was thinking
Runs Small
Runs small, my 7 pound 13 oz newborn fit into the small just barely – heâs 21.5 inches. Needed to size up to medium. That said the actual swaddle is great. He doesnât like his arms bound so the option to let them loose Iâd great.
Meh
Didn’t work for us. Arms got loose and collar rode up into mouth. Pretty cheap material for the price.Wouldn’t recommend, just learn how to swaddle properly. They’ll occasionally find a way out no matter what
Best swaddle ever! Iâve been using it for a month and it fits my 3 month old perfect. She is 15 lbs and about 25 inches. I ordered a medium and large and the large was a better fit. It didnât bunch up around her neck and has room to grow. The arms have snaps for transitioning instead of Velcro, so you donât have to worry about baby getting scratched by Velcro. Best swaddle ever and couldnât recommend enough!
We have tried a lot of swaddles in the last 4 months with twins and these are the best. They are easier than any other swaddle to put on and keep those little arms tucked in tight. One huge factor in our house is how noisy is it to do a middle of the night diaper change. We sleep our twins in footed sleepers for warmth and have found that regardless of what swaddle we buy the easy access for diaper changes does not work to get both legs out of the sleeper so you have to release the Velcro. Some companies use the worlds loudest Velcro that not only startles the half asleep baby on the changing table but also the fully asleep baby in the crib. These swaddles are the exact opposite. The Velcro is strong but yet quiet. We are currently sleeping our babies with one arm in and one out to work on transitioning both out. They still fit great and hold the arm inside down well while the their arm is free to move and doesnât have a bunch of fabric under the armpit.I will say the only negative, not really a negative, is that there is a learning curve to this. Read the box when you get it and you will be fine. Placement of the baby is everything, if you try to Velcro them in at the shoulders you will have fabric bunched up at the face. You want to place baby shoulders above there they really belong and the Velcro will start at the armpits and go down to the hands. This will keep the fabric low and away from the face.
The only sleep sack that worked for our handsy baby! When baby was newborn, we could not swaddle like they did at the hospital with blankets- our baby always broke out of it. We tried the swaddleme Velcro swaddles which were huge and our baby hated. We tried the love to dream swaddle up but our baby wanted their hands out since they were up and close to the face. Then we tried this one and baby fought it when youâre putting it on, but love it once theyâre in it. Babyâs sleep has improved as well!
Worth buying this swaddle. Itâs soft, breathable and the thick band of bel OT makes it tough for little ones to sneak an arm out.
Love this swaddle! Itâs great material and super easy to use, especially for dad LOL! Love that it unzips from the bottom! Allows us change our baby in the middle of the night without unswaddling.
