Each Fancypants Newborn Nappy has a waterproof outer and soft microfleece lining. The best part is that the inserts are sewn into the nappy (4 layers of highly absorbent microfibre) making it extremely easy to use. Each nappy has snap adjustments to make the sizing just right and includes an umbilical cord snap that serves to expose the umbilical cord so that it can naturally dry. Our newborn nappies are made to fit the smallest babies and are great for premature babies, multiple births or those regular 'ol small bums. They fit most babies from approximately 2 - 6 kgs. Fancypants Newborn Nappies are easy to use. Simply place the nappy under baby's bum and fasten waist snaps. Snap down the middle snap if required, to make room for the umbilical cord.
