By swaddling your newborn baby with our Swaddle Bag, you’ll help them to feel secure and sleep soundly through the night. Traditional swaddling with muslins can be a little tricky to master at first, so our simple swaddle bags are a soft and safe alternative. The practical design of the Swaddle Sleeping Bag helps to prevent your little one from rolling onto their tummy and keeps them in a natural and safe sleeping position. Carefully crafted from bamboo and organic cotton ensures MORI’s swaddle bag feels comfortable against their delicate skin. Our signature material is incredibly breathable and thermoregulating, making sure your baby is warm in winter and cool in summer. The Swaddle Bag is suitable to be used from 15 days up to 2-3m depending 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.When deciding how to dress your baby underneath the newborn Sleepsack, we advise to use your own discretion. As general advice, in temperatures above 23°C little one can wear a short sleeve bodysuit or just their nappy. For temperatures between 18-21°C we recommend a long sleeve bodysuit or a full sleepsuit. Under 18°C we advise you to dress them in both sleepsuit and bodysuit.
