They are made of 100% cotton and each pack contains 3 brightly coloured extra large muslins. Size 90cm x 90cm. They are perfect for: • Swaddling your baby • Burp cloth • Sheet • Play Mat • Changing mat • Towel • Light-Weight Blanket • Lining your pushchair And much more… Cozios can work like magic in calming a fussy, tired or over-stimulated baby. The simple act of swaddling your baby in a muslin can help your baby to sleep for longer by helping to create the safe and snug environment of the womb. Swaddled babies are found to be more restful sleepers which is a real benefit to the development of a newborn baby as sleep is so crucial to brain development. After years of experience swaddling newborns to 3 months, we feel that Cozios are the perfect size for swaddling, if they were any bigger they could swamp a newborn and too much fabric could lead to over heating. Machine washable at 40c.
