Change out of his pull-up.

He dug through his backpack and found what Natalie packed for him.

A funnel. A bottle of filtered water, its contents carefully measured. A box of white powder. An empty screw-top bottle with a rubber nipple.

Littles had different dietary needs than other people did and there was an entire market for food meant for them. With his diet so meticulously planned by his father, most meals included the most nutritious (and expensive) formula available on the market.

It wasn't that Adrien didn't like the formula. It was sweet and it cured his hunger pains very fast. It's just that even babies can grow bored when all they have is milk.

Adrien dug into his backpack and was surprised to find that it also included a bag of pink lady apple slices and some graham crackers.

Thank you Natalie.

Since he'll be having lunch by himself, he might as well take care of his other problem.

In co-ed schools there were three different types of bathrooms: Boys, Girls and Littles.Boy and girl bathrooms were functionally similar, with boys rooms having less stalls and more urinals than the later. Bathrooms for littles were much more different. They had nothing but sinks and stalls, but their stalls were three times the size of a regular stalls. In those stalls was a padded bed, not unlike the kind you would find in a doctor's office. They also came with cabinets full of everything you would need for diaper changes with one-size fits-all diapers for littles and a diaper genie for trash. Littles and caregivers came in both genders, so Little Bathrooms were gender neutral.

Adrien could have called Natalie to pick him up and take him home until classes resumed, but he preferred to rejoin his friends after eating and he would have preferred to do so dry. His pull-up was at its breaking point and he didn't want obvious pee stains on his jeans if he had another accident.

Besides, cold diapers of any kind were icky.

He lurked outside of the littles bathroom and inched the door opened. He listened for activity.

Silence.

Perfect.

He gave a brief scope to make sure no one saw him as he walked in.
