Wee Urban's Cozy Basics Brand of Baby and Toddler Sleeping Bags are the perfect solution to keep blankets on and to help baby maintain a safe and restful sleep. Using a moderate weight pre-washed cotton blended fabric, our Cozy Basics Brand is both breathable and warm, making it a year long fixture rather than a seasonal investment for your baby's nursery. Designed with age appropriate neck and sleeve openings for a non-restrictive fit and extra length for extended wear. Fully or partially open two-way zipper provides for free leg movement for your active toddler. Fully closed zipper helps to prevent babies from crawling out of the crib. Available in 3 sizes, 0-6 months, 6-18 months, 18-36 months and several adorable gender neutral colors and prints.
