Last week we heard how officers asked the nurse if she thought her presence during the collapse of a number babies on the Countess of Chester's neonatal unit was just "bad luck" - she said "yes".

In one interview a detective asked her: “What were you thinking during that period?” Letby replied: “That it was a shock to have that many deaths.” The detective said: “It must have been devastating.” “Yes,” replied Letby.

Ms Letby denies murdering seven babies and attempting to murder 10 others between 2015 and 2016.

We'll be hearing interviews in relation to Child I first today - a baby girl who Ms Letby allegedly murdered on 23 October 2015

Cheshire Police detective Danielle Stonier is reading Ms Letby's responses, while prosecutor Philip Astbury is reading the questions asked. We're currently hearing about Child I's first (of four) collapses on 30 September. Ms Letby was the infant's designated nurse

Ms Letby said she was not 'unduly concerned' about Child I at the start of her day shift. At around 15:00 Ms Letby noted that Child I appeared mottled in colour with a distended abdomen. At around 16:30 an emergency crash call went out as her heart rate had dropped

Ms Letby told detectives she could not recall the specifics of this incident. She is then asked about the baby's second collapse on 12/13 October. Ms Letby recalls this incident, 'oh yes, this was when she was found apnoeic in her cot at night', she said

She told detectives she and a nursing colleague found Child I 'gasping' for breath - she gave rescue breaths via neopuff and doctors were called to assist

Asked about Child I's final and fatal collapse on 23 October 2015 - Ms Letby she can't recall the specifics of the night, but said she 'remembers her dying and her parents having time with her'

Ms Letby said she wanted to attend Child I's funeral but she couldn't as she was working

Ms Letby was asked about the below card she sent to the parents of Child I after her death, she told detectives she sent it as it was 'not very often you get to know a family as well as we did with child I'

Detectives found the above image on Ms Letby's phone. She was asked why she took a pic of the card, she said it was 'upsetting losing (Child I) and I think it was nice to remember the kind words I shared with that family'

She also said she 'often takes pictures of any cards I send even birthday cards'. She said this was the first and only card she had sent to a family of a baby she had treated

Ms Letby is asked about the incident on 12/13 October. Her colleague Ashleigh Hudson told police that she saw Ms Letby was stood in the doorway of the nursery where Child I was in the early hours and commented that she looked pale.

Nurse Hudson turned on the light and saw that Child I appeared at the point of dying and was not breathing. Detectives asked Ms Letby if she 'knew she was looking pale because you just attacked her?' 'No', Ms Letby said

Detectives point out that Ms Letby had carried out Facebook searches for the family of Child I seven months after her death. She is asked why she did this, she told detectives she did not remember carrying out the searches

We're now moving to interview summaries for Child K - a baby girl Ms Letby allegedly attempted to murder on 17 February 2016. It is claimed a doctor, Ravi Jayaram, walked in on Ms Letby as she attempted to kill her.

Ms Letby told detectives that she had 'very little memory' of Child K, other than the fact she was a 25week prem baby

In his evidence Dr Jayaram reported that when he arrived on the unit Child I's ET tube had slipped and her oxygen saturations were in 80s. Ms Letby was, according to the medic, stood near to the baby's ventilator

Ms Letby denied dislodging the baby's ET tube and said if she had noticed the saturation levels she would have summoned help

We're now onto summaries for Child L, a twin boy who it is alleged Ms Letby attempted to murder on 9 April 2016. Asked if she 'inflicted any injury' on Child L she told police 'no'

The Crown say that Ms Letby gave Child L an unauthorised dose of insulin. In her interview Ms Letby is asked where insulin is kept on the unit and what the process for administering it to a patient is - she told officers it was kept in a fridge and it would have to be prescribed

Ms Letby explained that the insulin was in a locked fridge in the equipment room - the keys for which are passed around among neonatal nursing staff as and when they are needed

Detectives asked Ms Letby if she attempted to murder Child L by injecting him with insulin, she said 'no'. Asked if he could have been injected by mistake, she said 'I don’t really see how' and said it was 'unlikely' such a mistake could be made

Police put the expert evidence of Dr Dewi Evans to Ms Letby, that insulin had been administered - she said 'that wasn't done by me'

Ms Letby was asked if she had 'any explanation whatsoever' for how insulin ended up in his circulation. She said 'no, not unless it was already in one of the bags he was already receiving'. Asked if she added insulin to a bag, she said no

We're now moving onto interview summaries for Child M - Child L's twin brother - who the Crown say Ms Letby attempted to kill on the same day

The court has previously heard that Child M suffered an unexpected life-threatening collapse at around 16:00 hrs on 9 April 2016. His heart rate and breathing dropped dramatically and he required full resuscitation by medical staff.

Ms Letby told detectives she did not know why Child M desaturated. The only thing she could recall was that it was a 'busy shift' as it was 'not very often we had that many babies in nursery one'

Asked if she had caused the infants collapse, she said 'I didn’t cause that and I don’t know who would have'. She denied administering air in a bid to kill Child M
