The Merino Kids Cocooi Swaddle is the world's first made from 100% superfine Merino wool and has been designed specifically for the NB-3mths age group. Swaddling with the CocooiSwaddle is safe owing to the thermo-regulating qualities of Merino wool and its clever, patented,"diagonal-wing" design. The Cocooi Swaddle is easy to use. For first timers, a little time, practice and patience will establish a bedtime routine that works for you and your baby. Merino's unparalleled breathability means no clamminess next to the skin, creating a perfect micro-climate around the body and helping regulate a baby's body temperature before it can properly do this itself. No extra covers are required as our Merino will keep your baby warm in the cold and cool in the heat and help prevent overheating, a common problem for newborns.
