An approved swim nappy is compulsory for all toddlers until they are fully toilet trained and must be worn over the disposable swim nappy or Turtle Tots aqua-nappy and underneath any wetsuits or swimsuits to prevent any accidents. Our Toddler Shorts are designed for 2-3 year olds and have a more grown up design, with neoprene around the waist and the top of baby's legs to ensure nothing gets out!
