The Book of Not Entirely Useful Advice by A.F. Harrold
Bloomsbury Childrens Books
A riotous celebration of words and a modern take on cautionary tales - featuring advice on parrots, gravy, mathematics, castles (bouncy), spiders, vegetables (various), breakfast, cakes, and removing ducks from soup. Advice comes in many shapes. Poems come in many shapes.
And so, it follows, poems of advice come in many shapes too. Sometimes they look you in the eye and say, 'Do this! Don't do that!' Sometimes they sidle up beside you and whisper, 'Have you ever thought about ... ?'Not everything in this book is necessarily good advice, and not all of it is sensible advice.
(But if you take the bad or un-sensible advice and don't follow it, then it may become useful advice in its own way.)
