This is a sad disease that only affects only children with the rare case of divorce kids and siblings with a big age gap. This disease spreads in multiple different forms. Symptoms include being bratty, self centered, clingy, always searching for gratification, or being a total asshole. A poor child with this disease will only be effected by a few of these symptoms, never all of them.
Why is Jessica always so clingy? Yesterday I had to drag her while she clung onto my foot. She has major Only Child Syndrome.
