In 1975, Alona Frankel wrote and illustrated her first book, especially for her son Michael, on how to use the potty. Thirty-two years later, Once Upon a Potty -- Boy and Once Upon a Potty -- Girl are the classic books on potty training and have sold more than four million copies worldwide. These children's books help parents everywhere deal successfully with an often vexing challenge for the whole family.

Thanks to their timeless words and beloved images, Once Upon a Potty -- Boy and Once Upon a Potty -- Girl are being discovered and used by a new generation of parents. These two books, with their phenomenal staying power, target and meet the needs of an obviously perpetual market.
