Curious little children can lift over 30 flaps in each book to find the answers to many questions in this delightful series, with simple explanations and gorgeous illustrations on ever page. Follow boy and girl twins as they learn what potties are for, struggle to make their potties work, wet their underpants along the way, then finally triumph. Not only do they learn how to pee and poop on the potty, they also progress to the big toilet! Both an entertaining flap book and a practical guide, this book is invaluable for toddlers and parents.
