Happiest Baby SNOO Sleep Sack – 100% Organic Cotton Swaddle (Rose Planets, Medium) | Doctor-Designed

Experience a premium approach to baby swaddling with the Happiest Baby SNOO Sleep Sack, a 100% organic cotton swaddle designed for the SNOO Smart Sleeper. The Rose Planets pattern adds a soft, comforting touch, while the construction emphasizes safety, breathability, and gentle sleep support. The design is doctor-inspired and hip-conscious, with an International Hip Dysplasia Institute seal of approval that many families value when selecting sleepwear for their little one.

The SNOO Sleep Sack features wings that securely attach to the SNOO sleeper, helping maintain a safe back-sleep position. An extra-quiet Velcro closure minimizes nighttime disturbance, and a 2-way zipper provides convenient access for diaper changes from either the top or bottom without fully waking your baby.
