desertcart.com: Organic Cotton Baby Sleep Sacks Swaddles 0-3 Months Newborn Boy Girl Soft | Hands Up 3-Way Transitions to Arms-Free Wearable Sleeping Sack Bag Soft Arms Up Swaddle Blanket Snug Fit Calms Startle Reflex : Baby

Review: Our favorite swaddle - My baby loves this swaddle! Its very convenient for diaper changes because it unzips at the bottom. It fits her perfectly and there's plenty of room for her to grow and still be able to fit in it. I love how you can choose to keep arms tucked in or out. With other swaddles ive worried she will be too hot or too cold but this one keeps her at the perfect temperature. The quality of the fabric is very good also, easy to wash, nice and soft, very breathable fabric. I find myself using this swaddle more than the expensive halo swaddles we have. Planning to order a few more as well!
Review: We love this swaddle! - Perfect little swaddle blanket thing. My daughter likes to keep her hands up next to her head when she sleeps so traditional swaddles doesn’t work for her, but she loves to be warm and toasty, and this does the job very well. Keeps her from waking herself due to the startle reflex. It fits perfectly. I was honestly surprised at the overall quality, it’s really, really nice and super soft. I got it on sale and as soon as I received it I realized I would’ve paid full price 10x over 🤣 will definitely be buying more since there’s so many cute colors and we’ll definitely be wanting the next size up once baby is ready for that!

### ⭐⭐⭐⭐⭐ Helps my baby sleep at night
*by J***Y on February 23, 2024*

I LOVE this swaddle. My daughter prefers to have her hands up, even in utero, and hated being swaddled with them down. This saves the day. She is able to keep her hands up and rub her face to self soothe. She’s currently 2 months old and we do not use it, she wakes up ever 2 hours at night. When we do use it she sleeps for two 5 hour blocks in the overnight, waking up once to eat. We just sized up to the 3-6 months because she’s long and thin and the 0-3m size is a bit short and snug in the shoulder for her now. This item is soft, well made, washed well and I appreciate the double zip for diaper changes. As long as she is being swaddled, we will keep buying these and use them every night! I have several friends who are expecting and recommend this to everyone.
