"The Boy Who Forgot to Grow Up"

Prompt: Harry is finally eighteen years old, and is back at Hogwarts to repeat the last year of schooling. Most students are able to be classified by their fifth year, but due to the extremely stressful situation Harry was under, he hasn’t presented until now. Most of the world is made up of alpha, beta, omega, caregiver and little. Most alphas are also caregivers by default. Littles are extremely rare, and represent a pure and young soul, which is why Harry is completely confused when he gets classified. He was Harry Potter, why was he shoved into this sudden one percent of the population? OR Harry realizes he is little, and now must fight against the demons in his head, along with the overly concerned caregiver friends, who seem to insist on babying him, despite his very nice asking. Little have headspace’s were the mentally becalmed a toddler for a bit at a time, the are fully kids and use things like pacifiers but look the same as always Caregivers take care of little as a pseudo parent and get called the names like mom, dad, etc when the little is small
