And what do their actions mean? Luckily a brown owl can help him with the puzzle! This book about friendship and sign language was created by Gruffalo author Julia Donaldson with a group of deaf children in a workshop organised by the not-for-profit organisation Life & Deaf which helps deaf children to explore their identities through poetry, film, performance and art. Featuring Nick Sharratt's bright and accessible illustrations, What the Jackdaw Saw is another beautiful picture book from the team behind Goat Goes to Playgroup and Toddle Waddle.
