Nurse Lucy Letby, accused of murder, has told jurors she was stunned at the collapse and death of her first alleged victim.
Letby, 33, entered the witness box at Manchester Crown Court on Friday to give a second day of evidence.
She is on trial accused of the murders of seven babies and the attempted murders of 10 others at the Countess of Chester Hospital.
The prosecution says she targeted the infants who were treated in the hospital’s neonatal unit on various dates between June 2015 and June 2016.
Her barrister, Ben Myers KC, turned to the first individual allegation against her, that she murdered a prematurely born twin boy shortly after a night shift started on June 8.
Asked how she felt after the death of Child A, Letby said: “Stunned. It was a complete shock to all of us.
“I felt like we had walked through the doors into this awful situation. The first time I had met (Child A), the first time I had met his parents.
“It was a huge shock.”
