Discover our pretty swim diaper in Summer color! You may know them as a swim nappy, pool nappy, beach nappy or swimsuit nappy, and many of you have asked us for them. We have listened to you, and we are pleased to present the very first MyBabyNappy swim diapers! This summer, dress your baby with the cute Summer swim diaper. Made of perfectly waterproof PUL fabric, it will hold your baby's stool so that he can swim without problems. If baby stays by the water, you can add an absorbent insert in the diaper to help absorb and retain urine.
