Defendant says she was preparing infusion bag when Child M collapsed
At the time of Child M's collapse at around 4pm on 9 April 2016, Lucy Letby says she was preparing a bag of dextrose for Child L with another nurse.
Asked the first thing she recalls about Child M's deterioration, Letby says she remembers his monitor alarm was sounding.
The defendant says she went over to find Child M "struggling" and not breathing.
Other parents in the room at this point were asked to leave, she says.
Another nurse and a doctor became involved in resuscitation attempts for Child M, Letby tells the court.
Other members of staff started the process of making Child L's dextrose bag from the beginning after it had to be abandoned to care for Child M, she said.
After that bag was eventually hung for Child L, his blood sugar remained low.
"Did you do anything to interfere with that bag?" Ben Myers KC, defence lawyer, asks.
"No," Letby replies.
Letby says 'error' that blood gas printout found at her home wasn't discarded
The court is shown a photograph of handwritten notes on pieces of paper discovered in a police search of Lucy Letby's home after her arrest in 2018 - some which relate to Child M.
Letby says the notes would be in her uniform pocket and would end up going home with her.
She says she had no other use for them.
Another picture shows a blood gas printout for Child M, which Letby also says would have stayed in her pocket.
"The question that arises, Ms Letby, is why it doesn't just go in the bin after that?" says Ben Myers KC.
"That's an error on my part," she says.
Letby says she had no use for any of the hospital records - some of which relate to babies involved in this case - found at her home during the police search.
I didn't want twins to be hurt, Letby says
Lucy Letby says she continued to care for Child L and M "quite frequently" over the weeks that followed the incidents on 9 April 2016.
Asked what kind of care she provided, she says: "I did my best for them".
"Did you want them to be hurt?" Ben Myers KC, defending, asks.
Letby says she didn't.
The twins were discharged on 3 May 2016.
Lucy Letby, a former neonatal nurse, has been back in court for another day of cross-examination by the prosecution on Friday. She is accused of the murder of seven babies and the attempted murder of 10 others, and denies all the charges.
