Sleepy suffers from Chronic Fatigue Syndrome. His fatigue may worsen with physical or mental exertion, but doesn’t seem to improve with rest. Because of this, Sleepyhead is often very tired, can struggle with memories or concentration, physically weaker from body aches, and headaches. It’s not uncommon for either of his mothers to purchase him sleeping potions or elixirs to try and alleviate his exhaustion. Even if the magic doesn’t help as much as he’d like, Pinkie and Sky have tricked out his bedroom, turning it into his sanctuary full of black-out curtains, soft string lights, weighted blankets, white noise machines, a perch, a huge bed, and plenty of floor pillows if he’s unable to make it to the bed. And with his chronic illness, it can be difficult for Sleepy to keep up with his friends, even if they try to move at his pace.
