We're happy to help! All SNOO sacks have armholes at the shoulders for comfortability, so if your baby prefers to sleep with their arms free during naps and nights, you can certainly do that. Older babies (usually around 4-5 months) have more coordination and can sleep well with one or both hands-free. We hope this helps! Please do not hesitate to reach out if we can be of any additional assistance. **Q: This says it is 100% cottony but the tag says one of the shells is polyester?** A: Hi Sarah, Thank you for contacting Happiest Baby! Our swaddle sacks are made with 100% GOTS certified organic cotton + a bit of polyester mesh (the mesh feature reduces overheating). Please let us know if you have additional questions. **Q: How can you tell when to size up besides the baby’a weight?** A: If the Sleepea swaddle appears to be snug length/width-wise then it may be time to size up. **Q: Can my baby keep using this after rolling if her arms are out? Can she use it after six months? Does it act as a sleep sack?** A: Hi there, Thank you for contacting Happiest Baby! You can use the Sleepea swaddle outside the SNOO until it doesn't fit your little one anymore. As long as their arms are unswaddled so they can catch themselves if they roll over, it is completely safe. If you have additional questions, please let us know. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Comfy for wiggly babies; inescapable! *by C***T on 18 April 2026* We’ve tried so many swaddles of various styles for our wiggly baby.

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 doesn’t 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. ## Frequently Bought Together - Happiest Baby Sleepea 5-Second Swaddle - 100% Organic Cotton Baby Swaddle Blanket - Doctor Designed Promotes Healthy Hip Development (Ivory Planets, Small) - HALO 100% Cotton Sleepsack Swaddle, 3-Way Adjustable Wearable Blanket, TOG 1.5, Baby Blue, Newborn, 0-3 Months --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/526644085-happiest-baby-sleepea-5-second-swaddle-100-organic-cotton-baby](https://www.desertcart.us/products/526644085-happiest-baby-sleepea-5-second-swaddle-100-organic-cotton-baby) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-05*
