SWADDLE UP BAMBOO LITE 0.2 TOG uses a single layer of luxuriously soft & ultra-breathable viscose from Bamboo to reduce the risk of overheating. The fabric is breathable and temperature-regulating and is ideal for warmer temperatures between 24°C - 27°C. The first step to achieving deeper sleep is our Love to Dream Swaddle Up, the award-winning baby swaddle that keeps your little one's arms in a more natural upward position, with a hip-healthy design and helps prevent night-time waking from your baby's natural startle reflex. The unique ARMS UP design of SWADDLE UP replicates your baby's behaviour in the womb, allowing the natural ARMS UP position & allows them to place their hands to the mouth for true SELF-SOOTHING . For best fit result please select size according to your child's weight, not their height or age. You must stop using SWADDLE UP ️ when your baby shows signs of trying to roll & transition to SWADDLE UP ️ TRANSITION BAG or SUIT.
