Everyone Poops by Taro Gomi
Elephants do it large; mice do it small; people do it medium-sized. Some do it while moving; others do it while stationary; animals do it outdoors; humans do it indoors on a toilet. In this short-but-to-the-point illustrated book, the scoop on poop is explored in many of its various permutations. A suitable and tasteful intro for curious kids on a subject that is, perhaps, difficult to explore.
A Potty for Me! by Karen Katz
Written from a child's perspective, this lift-the-flap, rhyming book portrays the awkward and tentative first attempts of using the potty. Watching the child play, sit on the potty, eat, sleep, sit on the potty unproductively some more until, finally, success. Get your kids to join in and repeat "I'm so proud of me!"
Your New Potty by Joanna Cole; illustrated by Margaret Miller
Acclaimed, prolific children's book author Joanna Cole has written a supportive and reassuring book on the fundamentals of toilet training. Topics such as when to start, how to get your kids ready to begin, transitioning from diapers to underpants, and--inevitably--the accidents are covered. Forty color photos and a guide for parents help both kids and their parents reach this important milestone.
You Can Go to the Potty by William Sears, Martha Sears, and Christie Watts Kelly; illustrated by Renée Andriani
Based on William and Martha Sears' philosophy of "attachment parenting," this book expounds on the theory that potty training should be pressure-free and a natural occurrence, letting the child signal to you that he is physically and emotionally ready (on his own timeline), while the parents assume a more supportive role.
Fuzzy Bear's Potty Book by Bentley Dawn; illustrated by Krisztina Nagy
