Babies love feeling comforted whilst they're sleeping, our swaddle bag replicates the natural cuddle of the womb. We created the bag to make life simpler, as traditional swaddling can be a little tricky to master at first. The practical design of the swaddle bag helps to prevent your baby from rolling onto their tummy to ensure a safe sleeping position. Crafted from organic cotton and bamboo for a soft feel on your baby's skin. The swaddle bag is suitable to be used from 15 days up to 2–3 months depending on your little one’s development, which is approximately 5lbs (2kg) to 12lbs (5.5kg). It also has adjustable arm poppers so your baby can be snugly tucked in or given some freedom to have their arms out. Our swaddle bag has no tog or additional filling so can be used all year round with suitable clothing worn underneath (see below for details). How to dress your baby in MORI’s swaddle bag: The MORI swaddle bag can be used all year round, as it is fully lined on the inside but does not have additional filling inside. You can use it in different room temperatures without worrying about baby overheating. Our MORI swaddle bag has been tested at our factories in accordance with British Safety regulations for Safety of Children's Sleep Bags (BS 8510:2009). All chemical and hazardous materials testing are outsourced and in compliance with UK safety standards. Product certified by Standard 100 by Oeko-Tex, which ensures it is not harmful to the skin.
