We have worked with children and young adults so we know what they want from their writers.
With older children, we are prisoners of fashion as much as of our talents, but children are loyal. If they like your style or your characters or narratives, they will lap them up…
Children, like adults, do not like to be fed. Let them discover and explore through your characterisation and creativity, but remember their life experiences are limited and different to yours. Universality is key. They, thank goodness, do not reside in your head.
Above all, enjoy your creations and they will come alive on the page.
