So if she was there actively looking for signs of medical distress, and saw some, wouldn't she rush to the cot and begin emergency aid? I mean, instead of standing there and asking ' if baby looked a little pale?'
It seemed like she was wanting the other, less senior nurse, to make the call and take over.
Also, are you ignoring the other main issue, which is how she could see when she came from the brightly lit hallway into the much darker room and with the cot partially covered by a flap ?
I've watched a lot of trials over the years. I rarely, if ever, have seen the defendant asking for a break from being questioned before lunch. Or for their testimony being cut down to 2 days a week, and from there, to half a day at a time.
It is very unusual. IMO
