CONTENT WARNING: This story contains diaper changing scenes, which is why I rated this story Teen.
Poor, timid Fluttershy is afraid to give up her diaper in favor of learning to use the potty. The rest of the Mane Six tease her for her fear while Princess Celestia supports her in a kind and loving manner. This story is one source of inspiration for this one.

Amen. That is the whole point of my story. Feel sorry for Fluttershy, exactly as you should do for canonical Fluttershy!
