Two leading consultants in the field, Professor David Southall and Dr Martin Samuels, have recently been suspended after allegations they falsely accused families.
Such is the concern that a support group, Dare to Care, has been set up to help parents. It has assisted 50 families who say they were wrongly accused. All but six -who are still fighting - have now been cleared.
