One little brother (married and divorced before I even get married lol but whatever works for him). And many half-siblings across the country I've lost track unfortunately. My dad has been everywhere and doesn't plan on stopping... Lmao
I have two, an older sister and a younger brother. See, here's the thing though. My brother is 12, but he's developmentally 10 months old, and the doctor says he's gonna stay that way. He also has way more things, like a one-of-a-kind case of Joubert Syndrome (which is already rare enough, last time I checked, there were only a thousand or so people worldwide who knew about it), he's going blind, he's in a wheelchair, and more. But he's our Jonathan.
