Violet and Rose are two young sisters living together with their mother. While both are generally good girls, Violet has a big issue: accidents. Mostly while sleeping, but sometimes in daytime. She wears pull-ups to sleep, but after another daytime accident and really bad manners from the girl, mom decides to bring it up a notch: she will be treated as a baby, and by extension, as the little sister.
As a fun little extra, some chapters will have little polls at the end where you'll be able to vote for what happens in the story.
