I like the idea/ concept of these swaddles / sleepers. The one thing I would want to change about the swaddler is the arms. Our baby is big for his age and I feel like I’m squeezing his arms into there. As for his sleeping, not much has really changed he still sleeps his normal intervals in the day & throughout the night (45 min day naps) 3-4hrs @ night

This was a hard purchase for me. I didn't think it would or could work. I was also scared the having the weight on her chest wouldn't be good for her. But my goodness. It really made a world of difference. Putting her down wasn't as challenging as it was before.
My only request to make this a perfect product it to make it waterproof. I think this would help with moms who breastfeed. So the babies don't have to sleep in a soggy sleeper from leaking let down. If you use this idea I'd want some of the profit

My baby is only 4 weeks old so I am hoping to come back to use and try again, she seems to hate her arms in the mesh sleeves and startles herself without sleeves so didn’t work for us right now,
Yulia V.
We love it! Thank you for making it :) I gave several as gifts
Mia S.
The swaddle style sleeper is too small even for my 6 week old who is about 11 pounds. I’m disappointed because I was really excited to try this style out!
Kelsey B.
Absolutely love these sleepers! When my son is fighting sleep or just plain cranky, I start putting him in this sleeper and he instantly calms down. It also helps him soothe himself back to sleep during the night better than the other sleepers I've tried.
Katie N.
I hope this product will help my 4month old son sleep little longer or through the night but he still wake up often. I do love the soft and breathable fabrics that work with my son eczema skin
Jaclyn l.
My baby saver!she has better sleep with this!highly recommended!
Amanda N.
We used arms up swaddle from month 2 to month 3 since our babe was fighting an arms down swaddle. He was relaxed the first time. So easy to put on!! We now have switched to the sack and the sleep success continues!
Alexis H.
Each night our LO wears it he sleeps better and better! Wish I introduced it when he was a newborn.
Jessica M.
This is by far the best sleep sack. We used it with my daughter and now my son. On the first night he slept 2 hours longer and by the first week he was sleeping 4 hours longer. Cannot recommend this enough.
Megan H.
The product itself is very soft, great quality but definitely did not help my little one sleep any better unfortunately :( she’s not a huge fan of wearing it, but soft fabric and nice quality! Wish it would have worked out better!
Daphne W.
This was a gift for a friend after seeing my grandson sleeping so soundly in your products. Well worth the price and hold up well.
Nicole B.
This swaddle has been a game changer. My little one sleeps better. It’s super soft.
Kasandra D.
My 6 week old started sleeping for 6 hours straight at night with the arms up sleep sack! She is so comfortable in it and we love it! I wish I would’ve bought it sooner!
Jessica S.
Easy to use and quiets my baby in minutes. Sleeps great.
