New Jammies' cozy Sleep Snuggles will have your child sleeping in comfort! Our double layered organic cotton design is warm and breathable. These sleeping bags fit perfectly over footie pajamas for cool evenings or can be paired with a onesie for warmer nights. In addition, the New Jammies Sleep Snuggle encourages baby to sleep on their back until they can comfortably roll over from their back or tummy and eliminates loose crib blankets for the prevention of SIDS.
