Just finished reading this. Very interesting - I think something struck a chord with me on every page. Probably because ds1 is quite like Sam (both have/had washing machine, iron, tumble dryer, clock obsessions, both have constant verbal stims, both enjoy yelping in buildings like churches, both almost non-verbal but not quite, both gluten free (Sam is casein free as well). Quite a bit of George thrown in as well- perfect pitch, ridiculous memory). She also does part time ABA- so it was very like reading my life.
Also it has a VERY useful bit on advice to friends. What sort of help to offer etc.
Off to order a copy for my MIL. Unfortunately it doesn't say "dont disappear to bed for 2 hours in the afternoon when you visit", but maybe she'll realise that herself after reading the book
