I think you’re underestimating how precise the care is for these babies. It’s not like your Nana being in hospital, getting her jug of water refilled every 6 hours, her mash and sweetcorn scraped in the bin if she only eats her fish fingers, and meds on the ward round twice a day. They are in intensive care, they are under constant watch (sadly this is sometimes LL), every single thing about their care is documented, their medication, their feeds, their oxygen, every time they’re handled, every single thing that goes in their bodies and comes out of their bodies is measured and documented. If they were typing notes as things happen they would never be off a screen.
