Baby Swaddle in Tanboocel® Bamboo Viscose - Astro Explorers
It's week two, the startle reflex is winning, and everyone in the house is awake again. A snug wrap is the oldest fix there is.
Rockets, astronauts, UFOs — and one very small space explorer about to fall asleep.
It measures 47 by 47 inches — the size that actually holds. Hospital-issue swaddles run about 44 inches square — and those missing inches are why the wrap that held at 8 p.m. is loose by 3 a.m. Three extra inches reads like a rounding error — until week three, when it's the difference between rewrapping and sleeping.
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. Soft pink ground with multicolored rockets, astronauts, flying saucers, planets, moons, and small stars.
One blanket, many jobs. The newborn swaddle is the first use. The swaddle phase runs 8 to 16 weeks for most babies; the blanket keeps working long after — stroller shade, nursing cover, tummy-time mat, light summer layer. 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. Hospital swaddles usually measure about 44x44 — and that shortfall is where wraps loosen overnight. The three-inch difference matters more than it sounds like it should.
Can I use a muslin swaddle as a nursing cover?
Yes. One square of muslin, five jobs: nursing cover, stroller shade, tummy-time mat, summer layer, burp cloth. Open-weave muslin breathes well enough that you're not creating a hot pocket while feeding.
