Harvey is an adult now, and should be spoken to and treated like one. Encouraged to develop independence skills in line with his abilities. Not shouted at and spoken to like a toddler.
One of mine is neurodivergent with learning disabilities. He’s 16 so I speak to him like a 16 year old, and encourage his support workers to do the same; offering him choices and input in all decisions to help him express what he wants/needs. Even health care professionals need reminding to talk to him, not me when we attend medical appointments together.
I don’t post photos/videos of him to social media, as I’m a normal parent who wouldn’t dream of breaching his right to privacy. Actually, that goes for my other kids too, if they want to share something on social media, that’s their choice to make, not mine to impose.
Harvey believing in Father Christmas should be a private matter, but I’d have thought college, if not KFP should be working with Harvey to help him understand Father Christmas is a lovely thing for young children to believe in but introduce him to the idea that is a story rather than real. My 16 year old, I mentioned, has not believed in Father Christmas from a young age, as he was so confused by how it was possible. Rather than add to the story, I told him it was something parents tell young children to make things seem more exciting, but as he was asking questions he was old enough for me to tell him. That made sense to him, and he never told his younger brother, although he’d throw me a comedy wink whenever anyone spoke about Father Christmas.
