Families calling for an inquiry into maternity care in East Sussex say they feel "ignored, exhausted and dismissed" after meeting the chair of a national review.
The group met with Baroness Amos on Wednesday, claiming she was poorly briefed and that no progress was made.
The families, who all lost babies under the University Hospitals Sussex NHS Trust, have been campaigning for 18 months for an inquiry and insist that senior midwife Donna Ockenden is appointed to lead it.
The Department of Health and Social Care (DHSC) said Baroness Amos would work closely with families to "uncover the truth".
