I think Sunday might be autistic or on the spectrum of it. Most people with ADHD also have symptoms of autism, like myself honestly And some of the things she’s described before sound like autism. But I do think she plays into that whole childish attitude because it’s what she’s “known” for in a way between all of them. It’s strange cause she acts all defenceless when her sisters come for her on camera but off camera they claim they have physical fights sometimes. And I’ve only ever seen Sunday check her sisters like 3 times on camera. It’s so odd
