Ms Letby is accused of killing the brothers, who were triplets, within a 24hr period at the Countess of Chester Hospital. The prosecution say Ms Letby murdered the boys by injecting air into their bloodstreams. She denies all charges.

First in the witness box is Dr Huw Mayberry, via live link from Australia. He is recalling his night shift of June 22 into 23 2016 and his examination of Child O that night - yesterday we heard from a nurse Sophie Ellis, who told the court he was 'stable' throughout that night

Dr Mayberry agrees with the nurse's observation, he says he remembers coming back on for his second night shift on 23 June and 'was obviously very shocked' to hear Child O had died that day. 'I felt that he was very well', he said

Dr Mayberry is asked if he saw anything to indicate Child O was in discomfort, during the early hours of June 22, he says 'not at all'

Ben Myers KC, defending, is now questioning Dr Mayberry - he says 'do you actually have an independent recollection of how (Child O) was that you saw him?' 'Yes', he says Mr Myers says 'you have no notes of your own to rely on, do you?' 'No', he responded

Dr Mayberry doesn't have any notes as he was crash bleeped away from Child O's cotside in the early hours of 22 June to attend another baby - only record of his examination was recorded by nurse Ellis

Mr Myers notes that between 10am on the morning of 22 and 9.30am on the morning of 23 June there is no clinical notes for Child O, he asks if that is standard practice He responds 'if you have a child were you are not concerned about them then it would not be unusual'

Dr Mayberry does say he was asked by a senior doctor why he had not made a note about his examination in the early hours - he tells the court he should have made one

Mr Myers repeats that without a note, it's difficult for him to recall all details of examination and Child O's condition. Dr Mayberry says 'if I could go back I would write it'

Dr Mayberry says he does remember being 'shocked' at Child O's deterioration the following day

Prosecution are asking Dr Mayberry further questions - they've asked him to spell out his responsibilities for the night of 22 June. He tells the court he was a registrar on call for four different units, neonatal, birthing, general paediatrics and emergency dep

Dr Kataryna Cooke is now in the witness box - she was a senior house officer at the Countess of Chester from 2015-2017. She is asked if she has an independent memory of her involvement with Child O's care - 'the only thing I remember was it was around Brexit referendum'

She is now referring back to her notes. She went on a ward round on the morning of 23 June - a note on her examination of Child O at 9.30am, shown to the court, state 'observations normal'

The notes state that he was moving onto a lighter form of breathing support, which was a 'positive sign'. Antibiotics were also stopped for suspected sepsis - Dr Cooke says most premature babies are screened for sepsis

Asked for her overall observations about Child O that morning, Dr Cooke says 'from the notes it doesn’t appear like I had any concerns about (Child O) and his clinical course was uncomplicated and he was making good progress'

The court is told that Child O was later found with a hematoma in his liver (which is an accumulation of blood). Dr Cooke is asked whether that could have been present at time of her examination at 9.30am

She says if that hematoma was present her 'review wouldn’t be normal, by which I mean observations would suggest baby is undergoing deterioration as oppose to normal observations and no concerns from night team or nursing team'

The judge clarifies that the hematoma was found post-mortem and that it's not alleged the hematoma was in existence at the time of her examination. Ben Myers KC, defending, agrees - saying they are not alleging it was present at that time

The court has previously heard that on post mortem un-clotted blood was found in abdominal space from a liver injury. There was damage in multiple locations on and in the liver which had bled into the peritoneal cavity

The court has previously heard that in the view of the Crown's medical expert Dr Dewi Evans the liver injury occurred before Child O's collapse and contributed to it

Nurse Melanie Taylor is now in the witness box recalling the events of 23 June

Ms Taylor was working the day shift on 23 June as shift leader. Ms Letby was Child O's designated nurse that day

Ms Taylor is asked how Child O was on that morning, from reviewing her notes she said 'I had no concerns about him, obviously he was premature....we felt he was stable at the beginning of the shift'

Ms Taylor has told the court that afternoon - around middayish - she recalls seeing Child O. 'I remember I thought I don’t think he looks as well as he did before'. She told the court she suggested to Ms Letby that he be moved to nursery 1 for closer observations

Ms Taylor said that Ms Letby said 'no, she felt he was okay and wanted to keep him in nursery 2 and wanted to keep the three triplets together' - Ms Taylor says she felt she was 'put out' by this

'I couldn’t put my finger on it, I just had a gut instinct I didn’t feel like he was as well', Ms Taylor said. Ms Taylor said she 'felt like (Ms Letby) was undermining my decision'

Child O remained on nursery 2 until he collapsed later that afternoon and moved to nursery 1. He eventually needed resuscitation, which was unsuccessful - Ms Taylor said she was surprised by the severity of his collapse

Ms Taylor has finished giving evidence. Judge has asked the jury to temporarily retire while he 'gets an update on the weather' and whether we can continue this afternoon

Court has now adjourned until tomorrow morning (due to concerns over weather/traffic)
