Harry Potter awoke, and he needed to go. Bad.

Harry slept like a baby after his first exciting night in his first year at Hogwarts School of Witchcraft and Wizardry, and there was a sense of irony in that statement. When Rubeus Hagrid crashed through his Aunt and Uncle's boathouse and told him he was a wizard, this definitely was not what he was expecting.

As it was explained to him, Mary Poppins was not just a famous literary character and Disney sweetheart. She was a real person, or at least she was based on a real person. Pamela Lyndon Travers, the person who wrote Mary Poppins, was actually writing about her own witch nanny. According to her and Mary Poppins, the most powerful of magic users were simple human babies, their magical potential degrading as they grew older. This revolutionized Magical Britain, finding that by keeping their children at this stage up to a certain point, their magic will stay strong and healthy for the rest of their lives. This meant that Harry was going to be handled like everybody else in Hogwarts, being treated as a baby. This meant that he was not going to feed himself, he was not going to bath himself, and - most embarrassing of all - no toilet.

His crib - the bed he was sleeping in - magically lowered its bars, allowing Harry, dressed in a red and yellow (the colors of Gryffindor House) pajama onsie to get out. His diaper - a modern, disposable diaper with the Hogwarts 'H' insignia stamped on it - was still clean. Being raised by muggles, Harry was already potty trained (long before his spoiled cousin was) and has been for years. Being put back in diapers and being treated as a baby was going to be difficult for him.

Harry was sitting in his now open crib, his leg shaking as he needed to pee. Bad.
