Hi, has anyone purchased this book recently? DS aged two has been referred for autism assessments and I've been recommended this book to help him with his communication/speech issues by other people on Mumsnet. I've found it on Amazon but it is over £70, and whilst I will buy it at this price if there are no alternatives, I'd ideally like it for less! It doesn't appear to be in print anymore and places like Waterstones don't stock it. The library service also doesn't have it available. Many thanks!
