To most people, a pebble on the beach is just that - a pebble. For a little girl with Pathological Demand Avoidance, it's much more and a very special bond is formed. To help with her anxiety, the little girl chooses Pickle the pebble to accompany her through all that life throws at her, becoming her soothing sensory friend. Light-hearted and sometimes emotional, this book is based on a true story. The Adventures of Pickle explores the roller-coaster ride that the whole family (including the little black dog!) goes through when faced with this little-understood part of the Autism Spectrum.
