The sleeping bag is made from 100% cotton in a beautiful pattern. It is ideal for comfort and warmth during sleep. The top is held together with snap fasteners for easy opening. Additionally, it has a wide zipper on its side so you will be able to change diapers without having to take off the entire sleeping bag. The zipper is lined with an extra label on the inside to avoid waking your little one. It can be used instead of a duvet or blanket and ensures that your baby will stay warm during sleep!
