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! Curious little children can lift over 30 flaps to find the answers to many questions about the potty. Both entertaining and a practical guide for toddlers and parents. 12 pages, for ages 2 and up.
