LANCASTER (AP) — A Pennsylvania mother who sued doctors and a medical practice over the 2010 death of her 2-month-old daughter has been awarded $4 million in damages.

Michelle Goldstein’s 32-day-old baby died of complications from pertussis, also known as whooping cough.

The civil lawsuit filed in March 2016 claimed Lancaster Pediatric Associates should have diagnosed and treated it earlier because the baby’s mother described having symptoms of the disease herself and asked that the baby be tested.

The doctors’ attorney Steven Costello tells LNP newspapers they plan to appeal.

The jury this week found the practice and two physicians liable for two visits when the baby started to show symptoms of pertussis.

A nurse practitioner reached an undisclosed settlement with prosecutors prior to the trial.
