I had an infuriating experience with a young child in the hospital, where routine checks were being performed at the worst possible times for his sleep cycles. Sleeping is so critical to healing. Could it be that hospitals are being counterproductive, sacrificing effectiveness for efficiency?
I woke up once in the night and saw a shadow with a tiny led light, carefully taking a look at the sleeping child before disappearing just as quitely.
(FWIW the nurse was there every night, but this was the only time I observed it.)
My daughter slept very well during those days, as did I.
IIRC they'd also plan with me in advance to know when the best time would be for checks and blood works, at least it came across as very thoughtful.
This was Norway, not one of the major hospitals, so not so relevant for many others except as proof that it isn't like that everywhere in the world.
