Well, the theme of discovery is quite likely. The diaper girl princess discovers new things about herself, her kingdom, and the magic around her. And there could be a theme of courage too. Despite being in diapers and perhaps seen as vulnerable, she has the courage to face challenges in the kingdom, like standing up to a mean witch or helping a lost animal find its way home.
Once upon a time, there was a little girl who loved Disney princesses. She always dreamed of being like them. One day, while playing, she put on a diaper as part of her pretend play. She imagined herself as a new kind of Disney princess, one who was still a baby princess. She went on adventures in her make - believe world, with her teddy bear as her sidekick, just like how the real princesses had their animal friends.
A third theme could be about the baby's comfort. The story may revolve around finding the best diapers to keep the baby comfortable, and how the family tries different products and methods to ensure the baby is happy in their diapers.
A chastity diaper story could also have a theme of transformation. Maybe the character starts off as a very normal person and through the use of the chastity diaper, they go through a psychological or physical transformation. This could be related to ideas of breaking free from social norms or finding a new sense of self that is more in line with their true desires, even if those desires are considered strange or outside the mainstream.
Another theme could be chaos and order. The presence of diapers in a 'full house' can bring chaos, like when there are multiple diaper changes needed at once. But then the family or caregivers work to bring order, by having a system for diaper changes, storing diapers, etc. This theme can explore how a household manages the disorder that diapers can sometimes cause.
In some cases, it could be a part of a unique world - building concept. If the anime is set in a world where magic or some strange phenomenon can turn people into different forms, a girl turning into a baby - like form with a diaper could be just one aspect of that strange and interesting world. It can add a touch of quirkiness to the overall setting of the anime.
One reason could be that she was too busy playing and ignored the urge to go. For example, if she was building a big tower with her blocks and was so focused on making it taller that she didn't pay attention to her body's signals.
Sometimes, if a girl is ill, for example, has a stomach bug or diarrhea, it will definitely lead to a messy diaper. Also, if she drinks a lot of fluids quickly and her body can't process it fast enough, that can also be a reason. Another factor could be that she is too engrossed in playing and ignores the signals from her body that she needs to go to the toilet, until it's too late and her diaper gets messy.
One possible plot could be about a teenage girl who has a medical condition that requires her to use diapers. She might struggle with self - acceptance at first, but through the support of her family and friends, she gradually becomes more confident. For example, her best friend could help her stand up to bullies who make fun of her situation.
One common theme could be innocence. The diaper is often associated with the early and innocent stages of a girl's life. Another theme might be growth and development, as the diaper represents a phase that a child will eventually grow out of.
