Love to Dream Swaddle UP Original is the only zip-up swaddle available that allows your baby to sleep in the arms UP position. The Swaddle UP requires no complicated wrapping, so everyone can swaddle right every time. Unlike traditional swaddles, the unique arms UP design of the Swaddle UP replicates your baby's behaviour in the womb, allowing movement of their hands to self-soothe. This is proven to give your baby a better quality sleep and be beneficial for their ongoing development.
