Modern Sleep Bags & Swaddle BlanketsThe modern swaddle blanket at Rosenberry Rooms is an updated take on the basic swaddling cloth. Made of bamboo muslin, it has a light, open, breathable weave that helps to regulate baby's body heat, and the more you wash these contemporary swaddle blankets, the softer they get! Swaddle wraps can also be used as nursing coverups, car seat liners, changing table covers, stroller blankets and portable crib sheets. The modern sleep sack is another way to swaddle your little one in cozy comfort. Made of cotton muslin, sleep sacks zip from the bottom so changing a breeze. Besides thermal regulation, modern sleep sacks and swaddle blankets are stretchy and durable, giving your newborn a feeling of reassuring warmth and safety.
