Well.
Finlay doesn't cope at all in shops unless they are ones that interest him. Even then he doesn't "cope" but he has enough interest to keep him focussed so he deal with them better. But that is all sensory and related to his autism. Shops with him are awful. I usually end up physically attacked. We're really hoping occupational therapy helps him with that.
Amelia is 'neurotypical' and honestly she is a fucking rotbag in shops. She isn't sensory at all. She is just incredibly spirited and totally impulsive. She touches everything, dances, zig zags, lays down and rolls around and swings and hangs off everything... She is feral in shops and so embarrassing 😂
