How is this child a “snowflake”? It’s not unreasonable to have a 10 year old use a restroom just a few feet away rather than have to go to another floor to use the restroom, is it?
It doesn’t sound like she’s a snowflake to me either.
She’s a special needs student with pulmonary disease who may have an accident in her pants with the amount of time it takes her to climb a flight of stairs.
