Thousands of mothers over the past seven years have had successive children removed by family courts in England, the BBC has learned. Court records for that period show 7,143 mothers were involved in repeat care cases - affecting 22,790 children. The research was carried out by the Universities of Brunel and Manchester and funded by the Nuffield Foundation. This is the first time such data has been produced. It backs up what judges have observed in their own courts for many years - that many mothers are stuck in a destructive cycle of pregnancies and care proceedings. The courts remove a young child or baby from a mother, owing to abuse or neglect, only to see the same mother return to court a year or two later, with a new baby, and unable to care for that one either. Most misuse drink or drugs - or both.
