This book will provide concise but comprehensive coverage of key developmental paediatrics topics, pitched at the paediatric trainee level. This will be aimed at Masters in Paediatrics (MPaeds) and MRCPCH postgraduate candidates, for preparation for their specialty examinations. Paediatric postgraduate students in the ASEAN region will also find this book useful. This book will be useful as a clinical guide for doctors from several sectors of the market, namely: public and private universities, public health (Ministry of Health) and private healthcare. This book will help upskill doctors and trainees to provide better healthcare to the public. The parts and chapters are organized so that if read sequentially, the reader will have the essential foundations of development before delving into the specifics of child development. But the different chapters in the book can also be read separately and in no particular order if the reader requires concise reference for a particular aspect of child development. It’s not meant to be only an exam preparation book as such, as in addition to the vital concepts to pass examinations, this book will also give trainees the scaffolding which they will need to learn the fundamentals of developmental paediatrics.
