A nurse accused of murdering seven babies and the attempted murder of 10 others broke down in tears in court during questioning about the death of one alleged victim in her care.
Lucy Letby was giving evidence for the second day at Manchester Crown Court and was being questioned by her counsel, Ben Myers KC.
Prosecutors said she targeted the children who were treated at the Countess of Chester Hospital's neonatal unit on various dates between June 2015 and June 2016.
She recalled how one child, identified in court only as Child E, deteriorated before dying in the early hours of August 4, 2015, describing how his abdomen become discoloured and he bled "from his mouth and nose".
Letby said she assisted during resuscitation attempts.
"Were his parents there?" asked Mr Myers.
"Yes," she replied.
"Was it something you wanted to happen?"
"No."
"Had you done something to make this happen?"
"No."
Letby said she was there when Child E died and helped care for him and his parents afterwards as his designated nurse.
She cried as she recalled bathing Child E, taking photographs, handprints and footprints.
The prosecution says she targeted the infants in Countess of Chester Hospital's neonatal unit on various dates between June 2015 and June 2016.
She was earlier asked about the first individual allegation against her, that she murdered a prematurely born twin boy shortly after a night shift started on June 8, 2015.
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."
Mr Myers said: "It is alleged of course that you did this - did you?"
Letby said: "No.
Mr Myers said: "What's it like to have that allegation made?"
Letby said: "It's awful. That day I was not even supposed to be working that night.
"It was just a shock to walk into that situation."
Asked if it had had a lasting impact, she replied: "You never forget something like that."
Letby, from Hereford, denies all the allegations against her.
