Happiest Baby Sleepea 5-Second Swaddle - 100% Organic Cotton Baby Swaddle Blanket - Doctor Designed Promotes Healthy Hip Development (Graphite Stars, Medium)

Q: Can baby move their arms up?

Hi Lauren, Thank you for contacting Happiest Baby. 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?

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?

If the Sleepea swaddle appears to be snug length/width-wise then it may be time to size up.

Q: Can just one arm be left out of the swaddle ? I'm looking to transition my 3 month old baby out of his swaddle

Yes! These swaddles are great because you tuck both, one, or leave both arms out. The shoulder area has snaps to close the swaddle if you want to keep your baby’s arms in. We used these to transition our son around 3 months. He now sleeps with both arms out at 5 months and we just ordered the next size up!
