The publication of the Green Paper ‘Every Child Matters’ and the passage of the Children Act 2004 marks a significant shift in thinking about and organising of children's services in England. While the Government has presented the changes primarily as a response to the Laming Report into the death of Victoria Climbié, they are much more than this. The changes build on many of the ideas and policies the Government had been developing over a number of years, which emphasise the importance of intervening in children's lives at an early stage in order to prevent problems in later life. This paper critically analyses the assumptions which underpin the changes and argues that the relationships between parents, children, professionals and the state are being reconfigured as a result and that the priority given to the accumulation, monitoring and exchange of information takes on an increasing significance
