SwaddleDesigns Baby Sleep Sack 12-18M – Cotton Muslin Wearable Blanket with 2-Way Zipper

Soft, breathable cotton muslin for growing babies

The SwaddleDesigns sleep sack for 12-18 months is crafted in 100% cotton muslin and adorned with a watercolor peachy pink floral pattern. The open weave feels airy against delicate skin, and the fabric becomes irresistibly softer with every wash. This is more than a sleep garment; it’s a cozy, breathable layer that supports your baby’s bedtime routine and everyday comfort.

Designed with care and practical safety in mind

Designed by a nurse and informed by widely respected safe-sleep ideas, this non-weighted wearable blanket is meant to replace loose blankets during sleep. A thoughtful zipper guard protects tiny skin as you zip, while a 2-way zipper offers convenient access for dressing at bedtime and quick diaper changes without undressing the child. The design invites calm, predictable bedtime moments for both parent and baby.
