Mum tells author Baddiel what his book means for son with autism

“When he reads your books, I see my boy in his true, pure form.” That’s an extract from an email Debs Butler sent to the comedian David Baddiel. She wrote to him after her autistic son Freddie found joy and relief in David’s children’s books. Today's Nick Robinson speaks to them both. (Photo: Debs Butler with her son Freddie.
