The Rainbow Bridge by Adrian Raeside  is a particularly compelling story for children, and is the centerpiece of a wonderful new resource for children who have lost a pet.
This book is paired with a rainbow sensory bottle for children to explore the vibrant blue sky, fluffy clouds and arced rainbows and shake to listen to the calming sound of rain.
