American Baby Company 2 Pack Waterproof Flat Reusable Multi-use Pad Protector, Quilt-Like Multi-use Protective Mattress Pad Cover for Babies, Adults and Pets, White, 18" x 27"

These fit perfectly in the dock a tot grande pad area. Quick story. I bought two dock a tot grandes for my daughters. They ADORE those things. Second night using it—daughter #1 has a blow out and soaks the brand. new. dock. The next day and a half was spent hand washing and wringing out the pad and letting it dry in my yard. Not the best.Fast forward. I realized I needed something to protect it. These fit perfectly and stop all blow outs from reaching the pad. They’re so good and such a good price I’m going to get more to sew a cover for the tubings as well!! Can’t recommend enough!
