Description

Swaddelini wraps your baby in a hug of innovative comfort and safety, ensuring their peaceful sleep and your piece of mind. As a new mother, Liz Hilton faced the same challenge many parents do - finding the perfect swaddle. Leveraging her expertise as a 3D knitting specialist with her company KNITit, Liz invented the Swaddelini. Engineered as a single seamless piece, it's escape-proof, soft, breathable, comfortable, and most importantly, safe. Our founder, Liz Hilton, created Swaddelini in her garage in 2017. Since then, Swaddelini has won awards, moved into a full-scale manufacturing facility in Holland, Michigan, and changed the lives of caregivers for the better. Our patented Hug Technology delivers continuous comfort reminiscent of a parent's embrace, inspired by therapeutic garments designed for children with special needs. The Swaddelini doesn't just help babies sleep, it enhances their wellbeing. The Swaddelini is expertly crafted from soft, sustainable, post-consumer recycled nylon. As 3D-knit sleep sack, it offers a soft touch and the ability to stretch, keeping your baby hugged but not confined. The Swaddelini is the easiest sleep sack to put on your baby. It features no snaps, no zippers, and no velcro, slipping on as easy as a sock. And, it's escape-proof because of its unique design. The Swaddelini features an easy access diaper flap, allowing you to change your baby's diaper in the night without having to unswaddle them. This helps them sleep peacefully while you care for them. The Swaddelini features hug technology in the chest and arms, helping soothe your baby to sleep when they experience the Startle Reflex.

    • Very nice product for newborns!
Color: Lavender Size: 6-12 pounds
I bought this for my newborn granddaughter. My daughter did not like wrapped swaddle blankets, as she was always fearful of them covering the babies face. The Swaddlini sleeper will never travel up around the babies face and keeps theirs arms in comfortable position, and allows for a little movement, instead of the "straight jacket effect". Also love the convenient bottom up opening, allowing for easy access for diaper changes. Material is soft and has washed well. It does come in various sizes, which is helpful. ... show more

    • Soft & Stretchy
Color: Lavender Size: 12-18 pounds
These are super nice and good quality, good for a baby who doesn’t want to be strapped in anymore but still likes the comfort of a swaddle. It’s warm but not to hot, size is accurate I believe.

    • Absolutely love this swaddle
Color: Grey Size: 12-18 pounds
I’m not usually someone to write reviews but this swaddle was 100% worth it. My son had been suffering from eczema for months and no mater what I tried he kept scratching his face making it worse. This is the only thing that has prevented him from scratching his face at night. He has also slept well through the night without waking up and scratching. It fit well and was comfortable for him. I would give this product 10 stars if I could. ... show more

    • Not long enough.
Color: Blue Size: 6-12 pounds
The product is good and good quality but I wish they were longer because my son is taller so he grew out of it in like three weeks and so I was disappointed given that they are pretty pricey.

    • LoVe It!
Color: Blue Size: 6-12 pounds
i've had my eyeball on these swaddalini's since before I ever found out I was going to become a grandmother 10 months ago. It took me a while to afford to buy one, but I am so happy that I did. My grandson and his mother live with me for the time being and boy, does he have a very strong moro reflex!! so much so, that it nearly startles him wide awake every time. I knew that this would not eliminate the moro reflex, but it has reduced it enough to where he does not even stir now when he has one. I bought this because he IS still able to have them. Normal swaddles drive me crazy and I feel like it's unsafe and unnatural for babies to be completely pinned down like that. Anyway, he now settles into bedtime as soon as we put the swaddelini on at night. We don't use it during the day because his day/nights are still mixed up at three weeks old. I got the blue and white and it is absolutely beautiful! The size fits perfectly right now and the material though? I do feel like it could be a bit softer, but it doesn't seem to bother him so I'm not going to knock off any stars for that. ... show more

    • WORST PURCHASE FOR BABY
Color: Grey Size: 12-18 pounds
Complete trash. I wish I could leave zero stars. My son is having a hard time getting comfortable for sleep, and I thought this would help regulate his nervous system. I’m no stranger to sleep sacks and swaddles as this is my third baby. This is for babies that already sleep well and like to leave their hands at their sides. My baby likes to have his hands under his chin. The fabric feels so cheap and traps heat leaving my baby really hot which is a no no since they have no sweat glands. The fabric feels like a bad stretchy pair of tights you might get at a cheap store and regret it. It’s hard to get their arms in and if you wait until fully asleep to do so, you risk waking them up. Once in, my son fought it so hard. He was uncomfortable and cried so much more. It looked like a straight jacket. Honestly a complete waste of money. I wish I could return but I missed my window and I already used for over a month. This swaddle is a scam. You are better off with a sleep sack. ... show more

    • Great
Color: Lavender Size: 12-18 pounds
Works well, looks good. Fits well. Soft and warm. There are slots for the arms separate from the body which came as a surprise. For this reason, it is a little harder to get on baby compared to other swaddlers where arms and body go in the same spot, but i like how this one lets babies arms stay down, and baby very rarely manages to get arms out. ... show more

    • Wanted to love, but my baby hated, difficult to use
Color: Grey Size: 12-18 pounds
I really wanted to love this swaddle. For reference, my baby is an escape artist when it comes to swaddles. He will get out of anything. I was hoping this would make him feel more comfortable so he could move, while still managing the moro reflex. But he hated it. This swaddle was also very difficult to use. You have to put your baby in from a small hole in the bottom and slide it up to their neck. It was challenging to use, and it didn't sit properly on the neck; it always slid down to the shoulders, so the baby would also be cold. I think it's a nice idea, but the product needs to be designed a bit better. It's also an extremely expensive swaddle, so I promptly returned it. ... show more
