How I see it:
You are empowering the caregivers - the parents and the Paediatric team - to explain, inform children about their illness, medical procedure.
You are providing tools to busy workers in medical teams.
You are giving much needed vocabulary to a Mum or Dad to enable them to share with their child how they are going to be helped.
You are demystifying illness.
You are colourfully, interestingly, graphically informing children - the patients - in a way that helps them understand how they will be helped.
You're teaching human biology and the issues the human body (our machine) comes up against.
These books can be shared on the eve of the intervention BUT your aim is they are in every school and public library so they educate and inform children who are not ill about bodies and their challenges. They show families (who are not going through the illness at the same time) how amazing the medical profession is.
You could be inspiring children to become doctors!
