    • An absolute God send!
This has truly saved us! I originally ordered this at 4 am, holding my newborn who wouldn’t sleep in her bassinet for a single second. She escaped her way out of every swaddle and sleep was evading us. I ordered this out of desperation and it’s bought us much needed sleep and sanity. My daughter will do 3 hr stretches happily in her bassinet in her sleepea. Here’s what we love: 1. Our little Houdini cannot escape 2. It’s seriously so easy and quick to get them into the swaddle. 3. Great, soft organic cotton material. 4. Washes and dries great. I will be giving this as a gift at all future baby showers. - I seriously cannot recommend this enough! As others have noted, this is a pretty thick swaddle. We live in a warm climate and do feel she does best in this with the AC quite low and wearing a diaper only. For very small babies, the dimensions make it challenging to do a diaper change without having to take it off. ... show more

    • Get them!!
Review Image by jess
These are our favorite swaddle/sleep sacks!! And having the warmer option makes it so nice for a mama that likes a chilly room at night. They’re so soft and cozy without being too heavy. And easy for Dad to manage😉 I recommend to everyone!

    • Comfortable for baby.
My two month old granddaughter loves this. It keeps her snug but gives her just enough room to stretch. It is made of high quality material. We are definitely buying again.

    • Best swaddle. Wished i had used it in newborn phase
The most soft swaddle. I wish i ordered this when my baby was a newborn. Easy to use and stress free in the middle of the night. Thicker and softer than regular swaddles.

    • Great for arms out or arms in
Our little one loves this swaddle. If you have a baby that likes to sleep with their arms out this is the swaddle for you. We love that the Velcro is inside the sack and keeps the swaddle firmly in place on the baby, there is no risk of this swaddle coming up or sliding down your baby. The arm holes are super convenient for when our baby wants to sleep with her arms out, but I like that you can also use this swaddle with their arms strapped down to their side for when they are being a little too wiggly and keep waking themselves up. This is the comforter swaddle so it is a lot warming than the other version of this swaddle but it's great for when it is cold or if your baby has an issue with keeping their body temperature up, but definitely look at the other sleeppea swaddle if you are needing one that is cooler and has more mesh for hot times. ... show more

    • So cozy our new baby sleeps 9+ hours every night
BEST sleep sack We transitioned my baby out of his snoo for travel purposes and decided to try this sleep sack (since it’s the same for the snoo) and it’s PERFECT! We sleep with the house on the cooler side 68/9 degrees and our son sleeps so much better since we tried this. I did try the love to dream and I think it wasn’t warm enough. This sack feels like baby bedding and we sleep under comforters so it only makes sense that they should be sleeping under something similar We love love it ... show more

    • Only for colder climates!!
Color: Ivory Size: X-Large
I loved the Happiest Baby sleep sacks for my baby when he fit in these. I unfortunately could not use this as it would make my baby wayyyy to hot! It is a great quality bag clearly intended to be used in cold climates! Little breathability, very thick and bouncy material, the fit runs a bit small as well. ... show more
