Quick guide for a perfect nappy fit: Our nappies come in a range of sizes to suit your baby, so make sure to check the sizing guide in the product pages. A nappy that fits well, should appear straight and equally proportioned on your baby. The leg cuffs should wrap neatly around your baby's legs and bottom. After putting on the nappy, run your fingers around these edges to make sure the leak barrier cuffs are pulled out. Cuffs being tucked inside are a common cause of leakage. Check the waist band is snug with the nappy placed just under the belly button. The tapes should be fastened symmetrically on the waistband on the front of the nappy. Cuddlies nappies have flexible triple stretchable sides which adapt to the baby's shape and movement to help you create a custom fit.
