Nurse Oakley's nursing note adds: "[3am Child D] crying and desaturated again to 70s. Commenced on 100% O2 via CPAP and picked up well but skin discoloured again but less than previously. Dr Brunton called to review; take off NCPAP, further fluid bolus and gas 1 hour cares attended to; [passed urine] +++ and passed meconium."
Mrs Oakley says she cannot recall the events around this collapse, and says her memory of it is limited to that of her notes.
12:35pm
A nursing note of drug infusion, which Mrs Oakley says the doctors believed Child D would need more fluid on board, is noted at 3.20am.
The fluid chart records for 3.30am 'restart expressed breast milk (1ml).'
The prosecution say the collapses had been of concern to nurses, and why the doctors were called.
Mrs Oakley said after the review, the doctors were "happy with her" and for fluids to continue to be administered.
She added Child D had passed urine and had a wet nappy, and so she was comfortable in changing her nappy.
"If I thought she was unstable, I would not have chosen to change her nappy. If the baby's unstable, they do not tolerate handling. Even cleaning them could cause them to be unsettled, with their heart rate going up."

The nurse added 'observations satisfactory' and Child D was 'handling well'.
The final observation readings were all in normal parameters at 3.30am.
12:42pm
At 3.45am, the nurse noted: "Monitor alarming, [Child D] desaturated again and [stopped breathing]. Called senior nurse Letby to help. Stimulation given."
Use of Neopuff was given at 3.52pm. A senior house officer was called to help. Dr Brunton called to help, resuscitation efforts began.
The prosecution asks if Mrs Oakley has a memory of this.
She says she does note, it was "just a blur, just very busy. She 'misbehaved' [had gone poorly again]. I don't remember specifically."
She does not recall if an alarm went off. From her notes, she called Letby to assist.
The initial 'stimulation' effort was, the court hears, to tickle the feet, trunk, ears, which can in itself get a baby stimulated enough to start breathing.
Mrs Oakley says she played a part in the resuscitation efforts.
