He just doesn’t seem to be able to do creative play, it’s sad but it’s almost like he doesn’t have an imagination. He’s never played with anything like action figures or anything like that - the odd occasions he is engaged it’s when he’s building a Lego models following instructions.
Sounds just like my DS. Finally diagnosed ASD at 11 years (We had been on the waiting list since he was 6 years).
He was an absolute sponge for learning facts so loads of TV documentaries and YouTube but often overwhelmed by new experiences so lots of outdoor stuff in familiar places: forest adventure play parks, Forest School (never joined in games, just swung in the tree, cooked at the fire pit and observed minibeasts), local playgrounds.
Indoors: soft play and big local museums about tanks, trains, cars, rural life, sealife with lots to see and learn about.
Also hates football. The only club he's ever been able to cope with is Youth Volunteering at our local heritage railway - loads of hard physical graft - which he adores.
He also loves cycling and will now take himself off on epic half-day cycling expeditions on the weekend.
Further inspired by Duke of Edinburgh Award, he is also volunteering weekly after school at a cycle sales and repair shop.
He is extremely bright, determined, rule abiding and academic.
Good luck, OP.
