Thanks everyone, I should have clarified...
DD is 11, she is mortified, but needs must & the less fuss by nurses the better - this is the paper mâché trays that go inside the toilet, she uses it herself in the bathroom & was told by the doctor to put it on the windowsill for me to photograph & then get the nurses to discard it - Doctor wants to see for himself, & the nurses are meant to keep a descriptive chart anyway, though seems some haven't been, hence why he now wants the photos.
We had yet another tray to discard - now 3 lined up on the windowsill attracting flies 
so on taking DD off ward for some fresh air with DH for a couple of hours - I mentioned to this nurse AGAIN that the trays needed clearing away - she just glared at me
Getting back to the ward, another shift had taken over - & the trays were still there 
thankfully we are the only ones on this ward at the moment! but I hated having to get the new nurse in charge to deal with the left trays & made a point of telling her I had mentioned it several times to the nurse on the last shift, who seemed reluctant to deal with it - she was lovely & dealt with it immediately
I made a mistake, it's a Nurse, not a student nurse, DD thought she was a student as she has been rude to her when I've been away in the kitchen too - DD calls her Grumpy Knicker 
She's back on duty today, so will see how it goes with the next tray to clear
Though this is just the tip of the iceberg as to things wrong here & poor handovers have been a huge issue all through
Nurse in charge yesterday is also a slack one & had me taking stool samples to the sluice myself when I first arrived - 4 days with practically no sleep meant I didn't even think to argue & don't get me started on my stolen shopping
Thanks for your input, it just seemed so picky compared to everything else wrong with this place, so I'd sort of lost perspective
Thanks Electric sorry to here you are going through it too, it's no fun at all - Hope your DS recovers & copes with the changes soon too.
They've thankfully now ruled that out for DD, but hers turned out to be a very bad blockage, down to the Gastroparesis part of her a Ehlers Danlos - which up until now we didn't think she suffered with, turns out she's had a blockage going back years & this has caused what seemed to be IBS related daily Diarreoh, turns out this was triggered by a bout of Gastroenteritis - they've also pin pointed a very bad allergy to something, but we don't know what yet - they are still trying to clear the blockage & we are here until it's at least at the "of little concern level"
I thought we were looking at Diviculitis, Chrohns or Colitis too though, so did the gastro doctor, so as tough as this has been for us all, especially DD, I know we've got off lightly & feel for you
