The booster pads below are meant to be worn inside another absorbent undergarment to increase the absorbency and minimize changes. They do not have a waterproof backing to them which allows the wetness to flow through the booster pad and into the diaper underneath and prevents leaks from the leg openings. This also allows multiple, stacked, booster pads to be used, if necessary. Please feel free to call our care experts at 800-563-0161 for assistance in finding the right products for your needs.
