Yes we’ve had a few of those, some from family members who ought to be a bit more clued up than some because my mum has been type 1 since 1967!
Visited my grandmother in her care home once, carer came round with some nice looking sticky buns and offered us one. Gran yelled out “she can’t have one” and carer nearly took them away, I yelled out “oh yes she can!” and we got our sticky buns! I tried so many times to explain to Gran that things had moved on a bit since mum was diagnosed and daughter can now eat pretty much what she likes as long as we match the insulin dose to the food, instead of matching the food to the insulin dose like mum always had to. But she never got it, bless her (she died in 2016 at the great old age of 98)
French teacher at primary school wanted to bring in samples of French food for the children to try, cheeses and pastries. I asked her for some details of what they were so that I could give daughter an idea of the carb count, and tried to explain that daughter would be allowed to try anything as long as she gave herself a dose of insulin. Well every time i mentioned the word “insulin” you’d think I’d have sworn at the woman or something and she kept going on “oh no, we don’t need that” and my daughter’s class ended up with all the cheeses while the other class got the pastries, which is exactly what i was trying to avoid!! I did wonder afterwards whether I should have explained that my daughter would only need to push a few buttons on her pump to do the insulin dose and would not be waving a syringe around, but oh well, never found out whether that would have made a difference or not!
Year 5 school party - DSN told as a trick to do with the pump so that daughter could eat what she liked for an hour or two and not have to count everything (basically enter a huge number of carbs and put it on a 50/50 multiwave bolus over 3 hours, used to work a treat when she was young but less so these days). Made sure she understood how to set the bolus up and left her to enjoy it. Got a phone call that afternoon asking if she was allowed to eat party food. Sigh, something has gone wrong then. She had set up the bolus and then some nosy teachers who didn’t even teach her class decided she was allowed to eat sausage rolls only. She said no she was allowed to eat biscuits. They tried to find her teacher to ask but she wasn’t in, same with previous year teacher, only then did they ring me, by which time most of the food had been grabbed and there wasn’t enough left to cover the bolus. She was panicking a bit when I picked her up, cancelled what was left of the bolus but still had to shovel glucose down her for an hour to prevent a hypo. I asked the staff what had happened, one in particular was very snotty and kept on about “It was a really huge plate of biscuits!” And when I tried to explain that yes she can eat them and had done all the right things to deal with it this woman kept giving me dirty looks as if I don’t know how to care for my own child!
Thankfully secondary school are much better clued up and have read the care plan properly and do a great job of looking after her!
