Some great ideas here!
The only thing I could think of was something along the lines of Do T1 children really need 1 to 1 care in schools? E.g. there is a little one in the school I work at whose mum insisted that her child have one person to turn to if something is wrong, so they employed a TA especially for that purpose and sent her on a one day course to learn about diabetes. TA is already complaining that she can’t get a proper lunch break because she has to be “on call” all the time, and if she isn’t there then we midday supervisors have difficulty sometimes finding someone who can/is allowed to deal with it. They also get the school staff writing down in a book every blood test result, bolus amount and carb count - WHY? Yes the hospitals seem to advocate keeping detailed notes like that, and we still do to some degree, but I can get all the information I need just by going through the memory in daughter's meters when she gets home, why make school staff do it?
Whereas my daughter was not much older than that when diagnosed, it didn’t occur to me to even ask for a special person to deal with it, I think my daughter would have gone mad if she'd had someone following her around all the time, and I wanted her to learn to do as much as she possibly could with minimal supervision as quickly as possible. So her class teacher and a couple of general TAs managed between them (although I was already working there then and wasn’t hard to get hold of if something went wrong, so that might have changed things a bit!)
Good luck with your dissertation, I hope you manage to find a good theme!
