The all-time favourite, now with sound button technology. There are four million children under the age of 5 in the UK and all of them will need to be toilet trained. This classic book has already helped millions of parents get their children through a life milestone with ease and some entertainment too. 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 board book edition will withstand such heavy use and even survive the occasional water spill too. The four sound buttons cover the essentials, with a dose of amusement: Wee-Wee and Poo-Poo; kitty meows (is it a milk bowl?); bird sounds celebrate success; 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. Since 1975, Once Upon a Potty has been THE potty training book. It has it all: bright graphics, simple language, a fun story and an anatomically correct hero. With an edition for each gender, the book relates directly to the child, making potty-training relatable and easy to understand. More than four million copies have sold worldwide.
