Oh yes! I do this with colleagues who are doing the diabetes training to support students who are unable, for whatever, to do their own diabetes care. It's been invaluable for all kinds of reasons. Part of my work when I actually am at work with my students with multiple additional needs, not supporting from a distance via the mediums of video calls, e-mails and the Royal Mail involves direct support with T1D students.
Now, this year, I've been lucky and all I really need to do to support is confirm the numbers on both meters and insulin pens, and ensure the food is actually eaten! Or deal with the hypo brain. Apparently, I have a reputation as a bit of a specialist for support with diabetes of all kinds with all its curveballs...
It's highly entertaining when I have to go through the training myself, which is absolutely essential for me to do this well, and I won't do it if my training is not up to date, but luckily I am now known to the training providers and they are more than happy for me to provide practical, hands-on examples and kit for those brave enough to try. Especially when the kit they bring doesn't match anything either I or the current batch of students use. I do agree to behave myself... With my direct colleagues, they are all allowed to practise doing blood tests on me, if they wish, which has probably been more helpful to them than anything else, they say. I also, if we have to do carb counts for students, make them practise working out my lunch.
