Baby Muslin Swaddle in Tanboocel® Viscose from Bamboo - Bears on Bikes

A newborn's arms have a mind of their own at 3 a.m. Wrap them well and the whole house sleeps longer.

Brown bears on bikes, coasting through rolling hills.

It measures 47 by 47 inches — the size that actually holds. A typical hospital swaddle is around 44 inches — close enough to work in the bassinet under supervision, short enough to fail at home at 3 a.m. Nobody shops swaddles by the inch — but the wrap that stays tucked is the one with inches to spare.

Material. Tanboocel® Bamboo Viscose, blended with cotton and woven into open-weave muslin. Tanboocel® is a branded bamboo viscose made through a closed-loop process — third-party verified, with a lower water and chemical footprint than the generic bamboo rayon most brands quietly label "bamboo." It gets softer after the fifth wash than on day one, the opposite of how cotton ages.

The print. Ivory ground with brown bears riding bicycles past soft green watercolor trees and gentle rolling hills.

One blanket, many jobs. The newborn swaddle is the first use. Most babies wrap up the swaddle stage by 8 to 16 weeks. The muslin then spends years as the everything blanket: shade, cover, mat, cloth. It outlasts the swaddle window by years.

When to stop swaddling. The arms-in swaddle ends the moment the baby shows signs of rolling — usually 8–16 weeks. The AAP guidance is firm on this. Past that point, switch to a 0.5 TOG muslin sleep bag (warm nursery) or a 1.0 TOG TENCEL™ sleep bag (everyday nursery) with arms free.

Adjacent products. Once the swaddle phase ends, the natural next step is a 0.5 TOG Muslin Sleep Bag for warm nurseries or a 1.0 TOG TENCEL™ Sleep Bag for the everyday 69–75°F room.

Care. Machine wash cold and tumble dry low. Tanboocel® takes the dryer better than bamboo rayon, with less pilling and shrinkage over time. Don't bleach; iron on low only if you need to.

Safety & certification. AAP safe-sleep compliant and tested to CPSC, CPSIA, and ASTM standards. The material is certified to OEKO-TEX Standard 100, and Loulou Lollipop is a Certified B Corporation.

Common questions

When should I stop swaddling my baby?

Stop the arms-in swaddle the moment the baby shows signs of rolling — usually 8–16 weeks. After that, switch to a 0.5 or 1.0 TOG sleep bag with arms free. The AAP's guidance is firm on this: a swaddled baby who rolls onto their stomach is at meaningfully higher risk.

What size swaddle blanket is best?

47x47 inches is the size that holds together. The hospital blanket's 44x44 footprint is the reason home wraps need more fabric to hold. The three-inch difference matters more than it sounds like it should.

Can I use a muslin swaddle as a nursing cover?

Yes. Nursing cover, stroller shade, play mat, burp cloth, summer layer — the post-swaddle résumé. Open-weave muslin breathes well enough that you're not creating a hot pocket while feeding.
