The topics covered within this book aim to consolidate some of the current thinking around pain in children. For many years it was believed that children, and in particular babies; did not feel pain. But over the last twenty years or so this perspective has changed and we have seen many highly specialised pain clinics being set up around the world, dedicated to address the needs of the younger members of the population -- thus acknowledging that children in pain are not simply "smaller adults", but have particular experiences and requirements that can only be addressed by experts in the field, who are aware of the developmental factors that may influence their pain experience.
