The Swaddle Up is designed to allow your child to sleep in a more natural arms-up position and have access to their hands to safely self-soothe. The hip-friendly design and innovative wings have been reported to almost double your child's sleep time. What is self-soothing? Self-soothing is when a child wakes up and falls back to sleep without the help of a parent or carer. To self-soothe and eventually fall asleep on their own, children often put their hands in their mouths or gently rub their cheeks. With unique wings, the Swaddle Up is designed to promote safe self-soothing. Self-soothing = calmer = more sleep. As soon as your baby shows signs of turning, you need to stop swaddling and switch them to sleeping without their arms wrapped with the Swaddle Up transitional sleeping bag.
