The Swaddle Up Pucksack 1.0T is an innovative baby sleeping bag that has been specially developed to promote a natural arms-up position. This position allows the child to use their hands to self-soothe, which can lead to a significant increase in sleep time. The hip-friendly design and unique wings support self-soothing by helping the child to fall back asleep without external help. The Pucksack is suitable for year-round use and provides a safe sleeping environment as it contains no loose layers that can be kicked off during sleep. It is also easy to handle and easy to care for, making it a practical choice for parents.
