Its unique silicone teethers offer soothing relief to baby gums. 4-way stretch cotton allows the self-soothing swaddle to give your baby a snug, comforting fit. Your baby will feel secure allowing for a more restful sleep. While the swaddle’s roomy sack design supports continued healthy hip development. Plus, a two-way zipper with tab covers at top and bottom allows for easy dressing and diaper changes.
