From today's report:
"In the early hours of September 8, Child G was moved to Arrowe Park, where she had been born weighing 1lb 2oz.
Medics suspected sepsis as Child G required ventilation support with 100% oxygen but gradually she improved and was breathing for herself a week later.
Her markers for infection also fell as doctors ruled she was clinically stable and no longer needed specialist care as she was returned to the Countess of Chester on September 16.
Letby is accused of overfeeding Child G with milk through a nasogastric tube (NGT) and/or injecting air into the tube."
It's evidence like this which really concerns me - the medics at Arrowe Park suspected sepsis, and clearly she had raised markers of infection which gave rise to this suspicion and which subsequently fell. It was also a week before she was breathing for herself again, so not the miraculous and instant recovery which I think they have tried to portray. That suggests to me that there was a very obvious cause for her deterioration, namely the sepsis. Surely that's a very easy one for the Defence to challenge?
