Agreed. And it may be that some of these things can be measured initially so that we can figure out what normal is, and then can be reduced to once an hour, or once a day.

It reminds me of when I was working in paediatrics, and we had a premature baby who had been very sick. We'd treated him for a long time, and he had gradually recovered, but he had persistent anaemia, and we couldn't find a reason for it. Eventually, we figured out that it was because we had been monitoring him so closely - taking blood every day. We stopped checking, and he recovered nicely.

thanks for the advice
