INNOVATIVE DESIGN Designed by an RN BSN and Nursing team, the Grow With Me Swaddle is a 5 stage swaddle that expands up to 18 months to fit your baby's growing needs, ensuring sound sleep at each milestone; patented design

5 STAGES OF GROWTH Eliminating the need to purchase several swaddles and wearable baby blankets, Woombie’s GWM swaddle grows into 3 multi-sized swaddle variations and further evolves into a large/extra large, arms-free sleeper

SELF-SOOTHING Encourages back sleeping and eases the transition from womb to world; the stretchy but snug fit moves "with" the baby, re-creating a womb-like environment and simulating the feeling of being held, touched, and cuddled

COMFORTABLE AND BREATHABLE The cotton/spandex fabric promotes gentle airflow; the design is hip and shoulder friendly and the narrowed waistline gently compresses the tummy, providing additional comfort for your baby

EASY TO USE No origami required, this easy to use one step baby swaddle will not unravel as a blanket can; two-way zipper allows for easy diaper changes
