The book that will help your kiddo play her way to the potty is also ACCIDENT PROOF! Our book is made from Tyvek, making it water, pee, and poop-proof. Seriously, drop it in the potty. Leave it there. It will be fine (as long as you don’t flush it). It’s rip and puncture-resistant, so when you’re about to pull your hair out, just chomp down on our book. We promise not to tell.
