She needs them

It was a lovely morning in Paris, as Marinette Dupain-Cheng, aka Ladybug, was waking up. She got out of bed to do some stretches, a part of her daily routine. Another part of her routine was something you wouldn't expect for a girl her age, as she took a good look at her diaper, which was currently soaked. Marinette had been incontinent her whole life, so all she wore were diapers.

After changing into a dry one and getting ready for her day, Marinette started walking to school where she ran into her best friend, Alya. "Hey, Alya! How was your weekend?"

"Great, though I didn't need two dozen diaper changes like you did." Alya replied. While Marinette's incontinence was known to the entire class, Alya was one of the few people who Marinette allowed to tease her when it came to her diapers. In all honesty, Marinette found some of Alya's jokes to be pretty funny.

With that, the two kept walking to school.
