As the parenting wars escalate and politicians and childcare gurus lock horns over how best to raise our children, Mariella Frostrup and her guests explore the theory of twenty-first century parenting - and the rather messier practice. This third series of Radio 4's parenting programme begins with a discussion of attachment, the bond between parent and child and the dilemmas at the heart of the care system. As they debate the needs of our most vulnerable children, Mariella and her guests share their research, their personal experience and some very different views on how best to bring up our next generation. Joining Mariella are Professor Michael Lamb of the University of Cambridge, the writer Kate Figes, Chair of the Careleavers Association Will McMahon, the journalist Camilla Cavendish and John Simmonds of the British Association for Adoption and Fostering. We also hear from John Timpson of After Adoption, Professor Sir Michael Rutter, Nushra Mansuri of the British Association of Social Workers and a mother and daughter brought together through adoption. Producer: Julia Johnson.
