Paediatrics, the branch of medicine responsible for the health and medical care of infants, children and adolescents from birth to young adulthood, is a relatively recent speciality with its origins in the mid-19th century. 1 Unlike many other areas of practice, the population it serves is unable to advocate for itself. This often results in paediatrics being overlooked in planning services and education. One should note that a long protected childhood is unique to our species and essential for human mental and physical health. 2 Dedicated paediatric teaching in the undergraduate/ postgraduate medical curriculum is essential, irrespective of the intended area of practice for the doctors in training. The reasons for this are as follows. Normal and Abnormal Growth and Development and Holistic Care Knowledge of normal growth and development in children including the limits of normal variation is essential in recognis-ing abnormalities in growth and development that require further investigation and management. Because this growth and development occur within a family construct, paediatric medicine is the most obvious example for students when considering the holistic environment in which medical care is trying to be delivered. Paediatrics includes a wide spectrum of diseases and developmental disorders, many of which are unique to childhood. It differs from other specialities in that the manifestations of the same disease will differ at different ages. The clinical skills required to assess a newborn, a 6-month-old infant, a 6-year-old child and a sixteen-year-old adolescent differ considerably. The spectrum of disease has changed from a focus on infections and under-nutrition to include disorders in development, behaviour and over-nutrition. Paediatrics, more than any other speciality, provides students with the opportunity to apply their knowledge of advances in genetics, metabolism, systems biology and immunology. Paediatrics also provides the most training and exposure to disability and its impact on the family. These important lessons are relevant to medicine throughout the patient's life. Preventative care, in the form of vaccination policy and practice, has dramatically modified the health of the world, and infancy and childhood are the ideal window for intervention. However, commencing prevention during childhood is relevant for more than just infectious disease. Many serious physical and mental disorders of adulthood have modifiable precursors in childhood. 3,4 Studies to identify the risk and the protective processes of chronic diseases of adulthood will come from life course epidemiology which examines how biological programming in utero and later lifestyle factors interact to produce the
