With Once Upon a Potty, a parent reads the book to their child or allows the child to read it while on the potty. Not surprisingly, the book takes some wear. This new edition will withstand such heavy use.
The four sound buttons cover the essentials, with a dose of amusement: a fanfare for success; kitty meows (is it a milk bowl?); birds singing; and the flush-it's-all-gone finale. The three AG-13 button cell 1.5V batteries are removable and replaceable, and access is childproof.
