Knirose Transitional Swaddle Sack Arms Up - 0-3M Wearable Blanket (2-Pack)

Introducing the Knirose Transitional Swaddle Sack

The Transitional Swaddle Sack from Knirose is a cotton wearable blanket designed for newborns who sleep with arms up or are just beginning to roll. It offers a snug, comfortable fit that feels secure without being overly tight, while remaining breathable for overnight comfort. This set arrives as a practical 2-pack in 0-3 months, suitable for both boys and girls.

Why choose a transitional design?

Rather than a traditional, tightly wrapped swaddle or a loose sack, this transitional option provides a balanced feel. The design aims to support a calm night routine by offering a familiar, secure sensation that can adapt as your baby grows and moves through sleep stages.
