I recently bought my five year old son a fabulous book called 'Why is the Sky Blue? - The World According to Grandpa' by Chris Heath. It's a lovely story about a grandad who makes up magical stories when his grandson asks him questions. My son has a really close relationship with his grandad and the book really appealed to him. I can't wait for the next book in the series but, while I do, does anyone else have any entertaining and heartwarming grandad stories recommendations?
