The Wet Sensation Liner is a soft, suspended liner designed to be in direct contact with the child's skin, so they can feel a sensation of being wet, like with underwear, but with the extra advantage of leakage protection.
While the vast majority of wetness is absorbed, this suspended liner actually holds a small amount of wetness against your child's skin for a short period of time, helping them to associate these sensations with having to use the potty.
