This is a cotton made sleeping bag for babies. It is filled with cotton fur inside to give that extra cusioning to the baby. This can be used right from 0M to 6M baby. It is easy to carry. And also this can be comverted to a complete bed also for the baby by opening the zip provided. When you zip all the zippers it becomes a selling bag/bedding of the baby and when you unzip all it becomes a bed.
