I had a discussion regarding this some time ago with my grandchild who has an ADHD diagnosis. She has troubles being in noisy (especially visually) environments, yet she finds my home (relatively large home full of books, music always playing etc) comforting. She explained that all this stuff in my home is interesting for her and speaks with her - "It's you and grandma, it's full of stories". But the very modern and "must be comforting" environment in school full of patterns and pictures drawn on walls etc is just irritating – "There is no stories, just noise".

That's such a great insight. Thank you for sharing this.
