Swim Diapers

Swim diapers are a pair of pull-up pants that holds in solids while liquids passes through. Swim diapers don't include any absorbency, since their purpose is to prevent stool leaks in swimming pools. Most public swimming pools require a swim diaper for babies and toddlers.  Many pools allow you to use a plastic pant (such as the Gerber one below) over a cloth or disposable diaper.
