Baby Muslin Swaddle in Tanboocel® Bamboo Viscose - Tiny Engineers

Newborns sleep in stretches that feel random until the wrap is right. Then the stretches get longer.

Cranes, dump trucks, excavators — and the animal operators running them.

It measures 47 by 119 cm / 47 in — the size that actually holds. Most hospital swaddles come out around 112 cm / 44 in, and that small difference is exactly where a wrap goes from snug to loose at 3 a.m. Three inches sounds like nothing on paper; after about week three, you'll know which one you wish you'd been handed.

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. Light blue ground with construction vehicles (cranes, dump trucks, excavators) operated by elephants, dinosaurs, and cats, with traffic cones, warning signs, and dirt piles.

One blanket, many jobs. The newborn swaddle is the first use. After the swaddle phase ends — 8 to 16 weeks for most babies — the same blanket becomes a nursing cover, a stroller shade, a tummy-time mat, a burp cloth, and a light summer blanket. 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 Canadian Paediatric Society's 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 21–24°C 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. Tested to Health Canada's Textile Flammability Regulations, and to CPSIA and ASTM standards. The material is certified to OEKO-TEX Standard 100, and Loulou Lollipop is a Certified B Corporation.
