The All In One Swaddle Bag is made from the softest Bamboo from Viscose for your baby's delicate skin, yet just enough tightness to feel safe like they are being held and touched. The fabric has also enough stretch to ensure the baby is able to stretch out allowing their legs and hips to fall into a "natural frog like" position. Your baby's arms will feel free to move around and fall into their own "natural sleep position". The clever designed cuff can also be rolled back so baby and mum can have skin to skin contact during feeding. Made from the most softest of Natural Fibres Bamboo this product is perfect for summer with a 0.5 TOG rating. * Fabric is light and breathable to help keep babies cool.
