You Can’t Wear Underpants!

For the big, grownup boys out there, the potty masters in training, You Can’t Wear Underpants! is a cry (the big-boy kind!) of toilet triumph and persevering underpants pride.

Each turn of the page reveals an infant, animal, toy or other object obviously not suited for big-boy underpants: “No… YOU can’t wear underpants!” Each facing page beams with the brilliance of a self-proud, underpants-wearing heroine: “I wear big-boy underpants!” Underpants-wearer or not, all readers will be singing and rejoicing in the household’s new mantra—all day long!

You Can’t Wear Underpants! is a perfect companion to the potty training process at all stages, serving up read-aloud, chant-along fun and motivation, inspiring even the most reluctant to join the celebration and excitement of dropping the diapers and embracing the BIG boy underpants and true toilet independence.
