Colourful and practical, the Water Babies Happy Nappies are a firm classic. Manufactured from high quality 1mm thick neoprene, the Happy Nappy is comfortable, warm and easy to care for. Ergonomically designed to move with the baby as they kick and move about in the water, the Happy Nappy is shaped to cup baby’s bottom, whilst specialist waist and thigh ribs fit snugly to the child’s body, forming a seal that prevents any solids leaking out.
