The award-winning PiddlePad™ waterproof seat liner by Kiddopotamus protects car seats, strollers and joggers from diaper blowouts and potty-training accidents!  The PiddlePad is made with soft, absorbent layers next to baby's body and a waterproof vinyl outer layer to keep car seats and strollers dry and clean. A soft, upright harness shield protects the crotch harness.  The safe, contoured design fits easily and discreetly inside the child's seat and works with all harness systems.
