The Woombie Tencil Nursery Swaddle Blanket helps moms swaddle the way nature intended. It is a one-step, self-soothing sleep swaddle. This wearable blanket is ergonomically shaped with a 'hip-healthy' design and an arms-free interior encouraging self-soothing in the Hands Over Heart recommended sleep position. Mild compression mimics the sensation of touch, and a two-way zipper prevents unraveling throughout the night. The eucalyptus/spandex blend fabric is light, breathable, and provides a multi-dimensional stretch. Dress baby accordingly underneath depending upon season and nursery temperature.
