Does anyone know of any books that I can share with my son (aged 9) to promote a discussion about positive mental health? I'm worried about all the negativity in the media and the pressure to be/look/act in a certain way. We do talk about these issues, but it can be hard to make them easily understandable to children. He enjoys reading (if it appeals to him) and I was thinking a story might be a more effective way to support us to tackle this important issue.
