The boy was one of triplets and his brother, referred to as Child P, died just over 24hours later after also being allegedly attacked by Ms Letby.

Court is currently being read agreed evidence. First statement is from Amy Davies, who was a neonatal practitioner in 2016, she recalls having no concerns about the triplets in the days after their birth in late June 2016

A statement from another member of the neonatal team, who cared for Child O on the nightshift of 22 June into 23 June. She recalls seeing Child O with a swollen stomach - she was assigned to give him a milk feed via an NG tube

She raised concern over his stomach to nurse Sophie Ellis - she told her that she was aware and that she had flagged for him to be reviewed by a doctor. But she had been told 'to go ahead' with the feed and 'closely monitor' him

The neonatal worker said she remembers Child O 'squirming a little' when she began the feed

Dr Stephen Brearey, who was head of the neonatal unit in 2015/16, is now in the witness box. He is recalling his memory of the events of 23 June 2016 - the day Child O died

Dr Brearey wasn't the consultant on call that week - but he was in the hospital for a meeting. He passed through the unit and spoke to another doctor, who cannot be named for legal reasons, and was briefed on Child O. He stayed and offered to help

Manchester Crown Court has previously heard that Child O was in good condition and stable up until the afternoon of 23 June when he suffered a "remarkable deterioration" and died.

Dr Brearey has just reviewed a number of Child O's charts from that morning - he said 'none of those results were concerning; and that they were all in the 'normal range' and no evidence of infection

Court has just been shown an X-ray taken that morning, the radiologist notes 'the appearance is nonspecific but necrotising enterocolitis or mid gut volvulus cannot be excluded'

On another X-ray taken later that day, the radiologist notes 'the bowel is considerably less distended by comparison with the previous image, earlier that day' - notes no evidence of pneumothorax

Dr Brearey recalls Child O's first crash shortly after 14:30 on 23 June. He helped intubate the baby boy. He tells the court during this procedure he noticed an 'unusual' rash on the boy's chest

He said the rash was purpuric was 'noticeable'. He tells the court this was 'very, very concerning' in a neonat - his first thought for the case of the rash was infection. He notes Child O was on antibiotics and a blood test ordered

Child O crashed several more times that afternoon. On his last and fatal collapse at 16:15, Dr Brearey says that there was 'years of experience in that resuscitation' and that it was going as he would have wanted.

'But we just weren't getting a response back in terms of what we would normally expect', he said. Resus continued for well over 30mins but no pulse was recorded for Child O

The medic tells the court that by late afternoon the earlier rash noticed had 'vanished', which he found 'perplexing' - he said that ruled out it being a purpuric rash, as they're around for a 'good few days'

He said after 30mins the 'team agreed that to continue resus was going to be futile', this was discussed with parents it was stopped. Child O was then passed to his mum

Dr Brearey tells the court that after the death of Child O's brother, Child P, the following day he attended a debrief with other medical staff. He said Ms Letby was present in that debrief.

He said he asked how she was feeling and 'can remember suggesting to her to take the weekend off to recover' 'She didn’t seem overly upset to me in the debrief and told me at the time she was on shift next day which was a Saturday'

He said he was concerned about this because he, along with other consultants, had 'already expressed our concerns' about deaths on unit and a potential link to Ms Letby

He said on the evening of June 24 he called the duty exec senior nurse in the urgent care division. She was 'familiar with concerns'. The doctor told her he 'didn’t want nurse Letby to come back to work the following day or till all this was investigated properly;

He was told 'no' and that 'there was no evidence', the exec was 'happy to take responsibility' for Ms Letby continuing

Dr Brearey told the court that "further conversations" took place the following week and the decision was taken to remove Ms Letby from frontline nursing duties - instead placing her in a clerical role.

Ben Myers KC, defending, noted that Dr Brearey had first "identified" Ms Letby as someone of interest as early as June 2015 after the death of the first three babies in this case.

Dr Brearey had noted, with colleagues, that Ms Letby was present when those three children died in 2015.

Mr Myers put it to the doctor that he was guilty of "confirmation bias" towards Ms Letby and failed to look at "suboptimal care" given to the children in this case. "Absolutely not", he said.

Mr Myers put it to Dr Brearey that if there was a basis for his suspicions, he would have gone to the police. Dr Brearey said he and his colleagues were trying to "escalate appropriately" and needed "executive support" to decide the "correct plan of action going forward".

Dr Brearey added: "It's not something anyone wanted to consider, that a member of staff is harming babies. The senior nursing staff on the unit didn't believe this could be true."

Dr Brearey said with every "unusual" episode of baby collapse between June 2015 and June 2016 there was "increasing suspicion" about Ms Letby, which led him to eventually escalate his concerns and request she be taken off shift.

A doctor, who cannot be named for legal reasons, is now in the witness box. She is recalling the events of June 23 - when Child O collapsed several times and eventually died
