Bookseller Apush has withdrawn its textbook on the autism spectrum from its shelves because it believes the book will harm children and their families.

The company said on Friday that it will stop stocking the book, The Autism Spectrum and the Developing Child, because it was not appropriate for children under the age of six years old.

The book covers the diagnosis and treatment of autism spectrum disorder, a diagnosis which is not based on a neurological disorder.

It is a “child-friendly” book that was intended for parents and teachers to read with their children, according to the publisher.

The publisher said the book was not intended to be used for instruction in schools.

The statement comes after a number of books on autism have been withdrawn from bookshops in Australia and New Zealand due to fears they might be misleading or damaging.

Last year, a book about a 12-year-old boy who was diagnosed with autism was pulled from shelves after a local school banned its use.

The book was due to be released in June, but was pulled after concerns that it would encourage the spread of autism.

Earlier this year, the Australian Booksellers Association (ABA) said it was concerned about the safety of its members, who are all parents of children with autism.”ABA members have seen their bookselling and trade activity impacted by autism related books and videos,” the ABA said in a statement.

“We believe there is an urgent need to prevent the spread and misuse of this potentially damaging information, as well as to support families, children and teachers working to address this issue.”AP
