Thanks, Mindy. That is helpful. I know my mum researches constantly for ways of easing symptoms and useful tips and hints on how to cope with her more challenging behaviours. This has been an eye-opener over the last few years - I'd always thought someone was recognised as autistic and that was that. I didn't know it was something that could get progressively worse, but Small really is - a lot of her habits and mannerisms are a lot worse now than a few years ago, as if she's regressing rather than progressing.

The alternative diet treatment is something I'd heard of before, so is probably worth looking into further. She's a good eater, though - loves her vegetables and proper cooked dinners, rather than junk food anyday, which is a good thing.

Thanks for your support :)
